As an approach to determining the degree of integration of the Brazilian economy, this paper seeks to test the explanatory power of the Goldman Sachs Model for the expected returns by a foreign investor in the Brazilian market during the past eleven years (2004-2014). Using data for the stocks of 57 of the most actively traded firms at the BM&FBovespa, it begins by testing directly the degree of integration of the Brazilian economy during this period, in an attempt to better understand the context in which the model has been used. In sequence, in an indirect test of the Goldman Sachs model, the risk factor betas (market risk and country risk) of the sample stocks were estimated and a panel regression of expected stock returns on these betas was performed. It was found that country risk is not a statistically significant explanation of expected returns, indicating that it is being added in an ad hoc fashion by market practitioners to their cost of equity calculations. Thus, although there is evidence of a positive and significant relationship between systematic risk and return, the results for country risk demonstrate that the Goldman Sachs Model was not a satisfactory explanation of expected returns in the Brazilian market in the past eleven years, leading us to question the validity of its application in practice. By adding a size premium factor to the model, there is evidence of a negative and significant relationship between companies’ size and return, although country risk remains not satisfactory to explain stock expected returns.

This document provides a summary of a case study analyzing the performance of private equity funds compared to listed equity markets. It finds that private equity has higher average annual returns (8.21% vs 6.89%) and lower volatility (9.75% standard deviation vs 17.45%) than listed markets, resulting in a better risk-return profile as measured by the Sharpe ratio. Private equity also has lower maximum drawdowns. Diversification benefits are limited as private and listed equities are highly correlated during periods of market turmoil. Over the long-term from 1986-2012, private equity exhibited lower return fluctuations and generally outperformed during periods not characterized by financial crises. A multi-factor regression model finds that private equity
Determinants of the implied equity risk premium in BrazilFGV Brazil
This document summarizes a research paper that proposes and tests determinants of the implied equity risk premium (ERP) in Brazil. The paper calculates the ERP using current stock prices rather than historical returns. It finds several market fundamentals are significantly related to changes in the ERP, including changes in interest rates, debt risk spreads, US market liquidity, and the S&P 500 index level. The paper also compares using implied ERP versus historical averages and finds implied ERP varies with market events while historical averages do not.
The document discusses the Capital Asset Pricing Model (CAPM) and its use in evaluating securities and predicting expected returns based on systematic risk (beta). It analyzes stocks listed on the Muscat Securities Market (MSM30) index in Oman to evaluate securities based on their beta values and determine appropriate expected returns. Prior research studies on CAPM are also reviewed that test the model in various markets, with mixed results regarding CAPM's ability to fully explain returns based on beta alone.
The document summarizes research on value investing in emerging markets. It finds that:
1) A simple valuation model can identify emerging markets with higher expected returns compared to average emerging markets.
2) A portfolio of "undervalued" emerging markets identified by the model generates superior returns compared to benchmarks, with statistical significance.
3) Risk measures of the portfolio of undervalued emerging markets are close to risk measures of broader emerging market benchmarks, implying the higher returns are not compensated by significantly higher risk.
This document discusses hedge fund investment philosophy and manager selection. It makes the following key points:
1) Hedge fund returns come from systematic risk premiums, liquidity premiums, and alpha, which are amplified by leverage. True alpha is rare and hard to achieve consistently.
2) Successful manager selection focuses on those with a sustainable competitive edge investing in less crowded strategies, and an understanding of how to reduce risk in stressful times.
3) The selection process profiles managers' investment beliefs, alpha generation process, and risk philosophy to construct an expected return distribution for each manager.
The casual analysis of market moves in Q1 2016 does not fully explain the performance of hedge funds over the period. In addition to changes in global macroeconomic conditions and market dynamics over the course of the quarter, hedge fund performance was driven by the impact of momentum and concentration across portfolios and the structure and behavior of multi-strategy funds.
This document provides an overview of a research project on IPO pricing and growth rates implied in offer prices. It contains an introduction that discusses challenges in valuing IPO firms and approaches used. It also includes a literature review, research methodology with objectives and data sources, and a summary of key findings. The research derives implied cash flow growth rates from 184 European IPOs priced using discounted cash flow models. It finds the average IPO firm is expected to grow cash flows by 33% annually, though actual post-IPO growth rates are slightly positive. Forecast errors are associated with factors like market-to-book ratio and leverage, and negatively impact long-term stock returns.

Fine Tuned Income Approach in Real Estate Valuation in Emerging Europe: The C...Nigokhos Kanaryan, PhD
This document discusses a study that developed a modified capital asset pricing model (CAPM) to determine appropriate discount rates for real estate valuations in Bulgaria. The model incorporates systematic country risk, firm-specific risk, and time-varying risk. It was tested on two Bulgarian real estate investment trusts (REITs). The results found higher estimated costs of equity for the REITs compared to traditional CAPM, ranging from 6.9% to 16.6%. The study concludes the model is appropriate for emerging markets and could be expanded to value private companies or consider time-varying industry betas.
This document presents a cash flow based analysis of the return and risk characteristics of European private equity funds using data from Thomson Venture Economics. It finds that the average European fund draws down 23% of capital on the start date and 60% within three years. Funds return invested money to limited partners on average after 7 years. Analyzing 200 liquidated funds from 1980-2003, it finds an IRR of 12.7% and excess-IRR over the MSCI Europe index of 4.5%. Using a public market equivalent approach, it finds an average PME of 0.96 and value-weighted PME of 1.04. The document aims to develop a methodology to estimate returns and risks of European private equity
The document summarizes a study that uses the Capital Asset Pricing Model (CAPM) to analyze the risk and returns of 5 stocks from 2013-2015. It calculates daily returns, beta, alpha, and the correlation of individual stock returns with market returns. The results show most stocks had a slight negative excess return and negative Sharpe ratio, indicating average risk-adjusted performance. Betas were all statistically significant, with GE closest to the market. R-squared values ranged from 20-48%, explaining some but not all variation in returns. The analysis supports that CAPM provides useful but imperfect insights into the relationship between a stock's risk and return.
Capital asset pricing model (capm) evidence from nigeriaAlexander Decker
This document summarizes a research study that tested the predictions of the Capital Asset Pricing Model (CAPM) using stock return data from the Nigerian stock exchange from 2007 to 2010. The study combined individual stocks into portfolios to enhance the precision of estimates. The results did not support CAPM's predictions that higher risk (higher beta) is associated with higher returns. The study also found that the slope of the Security Market Line did not equal the excess market return, further invalidating CAPM predictions for the Nigerian market. The document provides context on CAPM theory and reviews prior empirical studies that have also found poor support for CAPM predictions.
This document analyzes the relationship between stock market liquidity and stock returns in 27 emerging equity markets from January 1992 to December 1999. It finds that stock returns are positively correlated with measures of market liquidity, including turnover ratio, trading value, and turnover-volatility multiple, in both cross-sectional and time-series analyses. This relationship holds even after controlling for other factors and contrasts with theories supported by studies of developed markets, where liquidity and returns are negatively correlated. The findings suggest emerging markets have a lower degree of integration with the global economy.
Parametric provides strategies for exploiting increased market volatility, including rebalancing portfolios and using options strategies. Rebalancing reduces concentration risks and volatility over time by selling assets that have increased in value and buying those that have decreased, capturing returns from volatility. Options strategies can also provide downside protection for portfolios while retaining upside potential. Parametric implemented an options overlay for a client in 2008 that protected against a 5-20% market decline while retaining upside to 30%, balancing protection and participation in gains.
Volatility trading strategies seek to profit from changes in a asset's volatility. Volatility measures how much the price of an asset fluctuates over time. There are several types of volatility strategies including volatility dispersion trading which buys options on index components and sells options on the overall index, volatility spreads which use option combinations to profit from different implied volatilities, and gamma trading which aims to benefit from unexpected events causing large price moves. Volatility is important for options as their pricing depends on assumptions about future volatility.
Understanding greek government bond spreadsIlias Lekkos
The aim of our research is to enhance our understanding on the fundamental behavior of the Greek Government Bond Spreads both before and after the Greek economic crisis. We do that by trying to address the following issues:
Which are the fundamental drivers of GGB spreads?
Is this set of driving factors constant or it varies relative to the situation in the Greek bond market and the size of the spreads?
Even for factors that are significant across the spreads distribution do they maintain a constant influence (constant betas) on the spreads or this varies as well?
Are Greek Government Bonds fairly valued given the levels of their fundamentals?
Are the risks around their fair value always symmetric or can we identify periods of positive (i.e. increased probability for narrower spreads) and negative (i.e. increased probability for wider spreads) risks?
Can we use the enhanced flexibility of the model for risk management purposes? That is, can we produce more accurate Value-at-Risk analysis for GGB spreads?
Finally, can we employ our model to explore the behavior of GGB spreads under various macroeconomic scenarios?

Investors have long recognised the compelling opportunity offered by emerging markets equities. Yet while returns from the asset class have considerably outperformed developed markets equities over previous market cycles, they have tended to be more volatile, severely testing investors’ resolve. Rather than attempting to time market allocations, or select regions or specific countries to over- or underweight, we believe that our proprietary emerging markets macro growth indicators and skill in identifying industry performance relative to them may offer investors a differentiated source of returns.

Hedge Fund Predictability Under the Magnifying Glass:The Economic Value of Fo...Ryan Renicker CFA
This document summarizes a study that examines the predictability of individual hedge fund returns based on macroeconomic variables. The study finds that a large proportion (over 60%) of hedge fund returns can be predicted using factors like default spreads, dividend yields, and market volatility. However, exploiting this predictability out-of-sample is challenging due to estimation risk and model uncertainty. The study finds that a combination strategy that averages predictive signals from multiple factors delivers superior risk-adjusted performance compared to strategies relying on single factors alone. This strategy is also more robust, especially during periods of financial crisis when predictor values deviate significantly from historical averages.

This document provides an overview and summary of Chapter 10 from an investments textbook. The chapter covers common stock valuation, including discounted cash flow models like the dividend discount model and relative valuation techniques like the P/E ratio approach. It emphasizes that students should understand how to value stocks by discounting expected future dividends or earnings. The chapter also discusses determining a stock's required rate of return and intrinsic value, as well as how valuation is affected by growth rates, payout ratios, and interest rates. Worked examples and practice problems are provided to help students apply these valuation concepts.
Environmental Finance article on Mark to Market vs Model January 2003Paul VanderMarck
1) The document discusses whether weather risk managers should value weather portfolios based on pricing models (mark-to-model) or current market prices (mark-to-market) as trading activity in weather derivatives has increased.
2) It weighs the arguments on both sides, noting that while mark-to-model may more accurately reflect the meteorological factors, it is difficult to isolate the supply and demand components of market prices.
3) As liquidity has increased in key locations, the author suggests using a hybrid approach that combines market data and modeling to value positions, in order to develop accurate portfolio valuations and risk metrics.
This document provides a 3-sentence summary of a research paper that develops a multifactor model to forecast the 1-year returns of actively managed equity mutual funds. The model uses forecasts of a fund's manager skill, style (based on factors like market, size, value, and momentum), and expected factor returns. When tested on German equity funds, the multifactor model substantially improved forecasts compared to a naive model, reducing the mean squared error by up to 30% and yielding returns over 200 basis points higher for top-decile funds.
This document discusses future contracts and the binomial tree model for pricing derivatives. It analyzes the stock prices of Apple and Facebook to compare theoretical forward prices to observed future prices. For Apple, the theoretical forward price is calculated and compared to the future price, finding small differences. For Facebook, future and spot prices are analyzed and seen to converge at maturity as expected. The second part uses the binomial tree model to calculate prices and delta values for European call and put options on the underlying asset. It finds that option prices increase with more periods to maturity but decrease as expiration approaches. The model is also used to price American put options and compare to European puts.
This paper examines the "variance premium", which is the difference between the squared VIX index and expected realized variance. The authors show that the variance premium captures attitudes toward economic uncertainty and predicts future stock returns over short horizons. They develop a generalized long-run risks model that generates a time-varying variance premium consistent with market return and risk-free rate levels. The model requires extensions to match the large size, volatility and skewness of the variance premium and its short-term return predictability. Calibrating the model to cash flow and asset pricing targets allows it to generate the variance premium and its return predictability features.
Tobin's q theory is a ratio that compares the market value of a company to the replacement cost of its assets. A ratio below 1 implies the stock is undervalued, while above 1 means it is overvalued. This ratio is used to inform investment decisions. It is calculated by dividing a firm's market value by the book value of its assets. While Tobin's q theory was shown to predict investment in 1960-1974, later data showed the ratio and investment diverging, calling into question how accurately it forecasts capital expenditures.
The document analyzes stock market patterns and the overall market. It examines the correlation between individual stock prices and volume and how they relate to market direction. The analysis finds that from 2007-2009 and 2013-2014, 5 randomly selected stocks (BLL, CAT, GIS, AON, MKC) followed the overall market's weak trends. Their price-volume correlations and beta values relative to the S&P 500 were low. However, the stocks generally moved in the same direction as the market during up and down periods. More data over varied periods would be needed to better determine if individual stocks reliably track the overall market.

This document examines whether the Capital Asset Pricing Model (CAPM) can predict stock returns in Ghana using data from selected stocks on the Ghana Stock Exchange from 2006-2010. The results found no statistically significant relationship between actual and predicted returns, indicating CAPM with constant beta cannot explain differences in returns. It was also found that some stocks were on average undervalued while one was overvalued over the period studied. The conclusion is that the standard CAPM model cannot statistically explain the observed differences in actual and estimated returns of the selected Ghanaian stocks.
This document discusses approaches to calculating the international cost of capital. It notes that while the capital asset pricing model (CAPM) is commonly used, it provides biased estimates in emerging markets due to unique country risks. The document evaluates 12 different models and recommends using a company's domestic cost of capital plus a country risk premium in basis points estimated through quantitative crisis signal and country rating models. It stresses the country premium should account for cyclical, exchange rate, solvency, political and business environment risks over various time horizons.

1) The study examines the economic importance of accounting information by analyzing how accounting data from financial statements can improve portfolio optimization for US equities.
2) Using a parametric portfolio policy method, the researchers modeled portfolio weights as a linear function of three accounting characteristics - accruals, change in earnings, and asset growth - and compared it to weights based on size, book-to-market, and momentum.
3) They found that the accounting-based portfolio generated an out-of-sample annual information ratio of 1.9 compared to 1.5 for the price-based portfolio, indicating accounting information provides valuable signals for optimizing equity investments.
Impact of capital asset pricing model (capm) on pakistanAlexander Decker
This document summarizes a research study that applied the Capital Asset Pricing Model (CAPM) to stocks traded on the Karachi Stock Exchange in Pakistan from 2003 to 2007. The study found that CAPM was able to estimate stock returns in the Pakistani market and showed the existence of a risk premium as the only factor affecting stock returns. The study used monthly return data from 5 portfolios sorted by size and book-to-market ratios. Regression analysis found the intercept was insignificant while the risk premium was significant, showing CAPM estimates stock returns accurately in this market. However, the study notes CAPM has limitations and future research could test different models or variations to further analyze factors affecting stock returns.
The document discusses the Capital Asset Pricing Model (CAPM) and its use in calculating the required rate of return for Greggs plc. It provides background on the development of the CAPM by Markowitz and Sharpe. The author then calculates the beta and required rate of return for Greggs using 5 years of stock price data and the CAPM formula. While the CAPM is widely used, the document also discusses criticisms of the model, such as its unrealistic assumptions and inability to explain all returns. Overall, the CAPM remains a commonly used model despite its limitations.
The document discusses defining a "Quant Cycle" to capture cyclical behavior in factor returns. The author argues traditional business cycle indicators do not adequately explain factor return variations. Instead, factors seem to follow their own cycle driven by abrupt changes in investor sentiment.
The author proposes a simple 3-stage Quant Cycle model consisting of: 1) a normal stage where factors earn long-term premiums, interrupted by 2) occasional large drawdowns in the value factor due to growth rallies or value crashes, typically lasting 2 years, followed by 3) subsequent reversals where outperforming factors reverse and underperforming factors recover. Empirically, this model captures a large amount of time variation in factor returns compared to traditional frameworks
This document analyzes the validity of the Capital Asset Pricing Model (CAPM) using data from the Karachi Stock Exchange (KSE) from 2011-2014. It finds that CAPM does not fully hold for the KSE. While expected and actual returns were slightly different for some stocks in some years, indicating CAPM may be applicable, there were large differences for many observations. Overall, CAPM did not accurately convey results for the KSE. The document reviews previous literature on CAPM which also found it does not always hold and may be more accurate for some stocks and time periods. The methodology used beta calculations to estimate expected returns for 30 KSE stocks which were then compared to actual returns.
This document provides a study guide and analysis for a case study on determining the appropriate discount rate for cash flows in Venezuela for Telmex's potential acquisition of shares in CANTV.
The study guide outlines the teaching objectives of understanding challenges in estimating the cost of capital in emerging markets. It also reviews different methodologies that have been used to incorporate country risk into discount rate calculations, including modified versions of the CAPM model. The analyses of these methods note their advantages and disadvantages when the perception of sovereign risk differs from private sector risk, as it does in Venezuela.
The document concludes by providing a teaching plan to analyze financial information, review risk calculation theories, consider the dilemma of what discount rate to propose,
An Empirical Assessment of Capital Asset Pricing Model with Reference to Nati...ijtsrd
"This study concentrates on empirical assessment of Capital Asset Pricing Model CAPM on the National Stock Exchange NSE . CAPM assists to determine a well diversified portfolio. The main objective of this research paper is to check the applicability of Nobel laureate’s model in Indian equity market by testing the relationship between risk and return, whether there is any direct proportionality in the expected rate of return and its systematic risk. It relates its results by using the beta systematic risk as a measuring factor. The study was being conducted for a period of 260 weeks from 7 April 2013 to 25 March 2018. 45 companies from NSE were picked as a proxy for the market portfolio. This research was done by using regression analysis on stocks and portfolio to find out the final results. Research of this study nullifies that this model is applicable to the Indian market and also contradicts its expected return and systematic risk which are linearly related to each other. Miss.

There are three main forms of market efficiency:
1) Weak form - Prices reflect all past price information. Technical analysis is not useful.
2) Semi-strong form - Prices reflect all public information. Fundamental analysis is not useful.
3) Strong form - Prices reflect all public and private information. No analysis is useful.
The Arbitrage Pricing Theory (APT) is a multi-factor model that does not rely on a market portfolio like the Capital Asset Pricing Model (CAPM). The APT allows for multiple factors that influence returns while the CAPM only considers systematic risk relative to the market.
Technical indicators like moving averages and oscillators
This document introduces the Two Sigma Factor Lens, which is a framework for constructing a parsimonious set of risk factors that individually describe independent risks across many asset classes yet collectively explain much of the risk in typical institutional investor portfolios. The lens is intended to capture the majority of risk in a holistic yet concise manner so that changes to factor exposures can easily translate to asset allocation changes. The document discusses how analyzing portfolios through a risk factor lens allows investors to better understand overlapping risk sources across asset classes and more efficiently manage portfolio risk.
This document analyzes whether small-cap stocks in the Brazilian stock market generate above-average returns compared to large-cap stocks. It develops an automated trading system using technical analysis indicators like moving averages to generate buy and sell signals. By applying this system to portfolios of small-cap and large-cap stocks from 2007-2016, the study finds that while small-caps may offer higher return potential, the profitability of technical analysis strategies is similar for small-caps and large-caps in the Brazilian market. So small-caps do not clearly outperform as investments according to this analysis of the country's stock exchange.

This document provides an introduction to portfolio management and the single-index model (SIM) and capital asset pricing model (CAPM). It first describes SIM and tests it on eight companies, analyzing the results. It finds SIM reduces the workload of estimating variables but oversimplifies risk. The document then introduces CAPM, tests it on the same companies, and analyzes the results and merits and demerits of CAPM. It concludes by discussing the sensitivity of the models to sector characteristics.
The document proposes a practical method for quantifying country risk in emerging market valuations by primarily considering its impact on projected cash flows rather than the discount rate. It discusses flaws with commonly used approaches that add a country risk premium to the discount rate. The method involves building a model integrating relevant risks, conducting a Monte Carlo simulation to obtain a probability distribution of present values, and comparing this to valuations using different discount rates. An example is provided to demonstrate the approach.
1. The document analyzes whether systematic rules-based strategies based on traditional and alternative risk factors can successfully replicate the performance of various hedge fund strategies.
2. Regression analysis shows the factors explain a substantial portion of hedge fund returns, though the explanatory power is higher in-sample than out-of-sample. More dynamic strategies are harder to replicate than directional ones.
3. Out-of-sample, a rolling-window approach to estimating time-varying factor exposures works as well or better than a Kalman filter model for most strategies. Replication quality varies by strategy, with more directional strategies like short selling replicating better than dynamic ones.

Testing and extending the capital asset pricing modelGabriel Koh
This paper attempts to prove whether the conventional Capital Asset Pricing Model (CAPM) holds with respect to a set of asset returns. Starting with the Fama-Macbeth cross-sectional regression, we prove through the significance of pricing errors that the CAPM does not hold. Hence, we expand the original CAPM by including risk factors and factor-mimicking portfolios built on firm-specific characteristics and test for their significance in the model. Ultimately, by adding significant factors, we find that the model helps to better explain asset returns, but does still not entirely capture pricing errors.
This document provides an overview of capital market research, which examines the impact of financial accounting and disclosure decisions on share prices and returns. Capital market research analyzes statistical relationships between financial information and share price movements to assess how investors react in aggregate to new information. It relies on the assumption that markets are semi-strong form efficient and quickly reflect all public information in security prices. The research is useful for understanding how alternative accounting methods and disclosures influence investment decisions.

Interval observer for uncertain time-varying SIR-SI model of vector-borne dis...FGV Brazil
The issue of state estimation is considered for an SIR-SI model describing a vector-borne disease such as dengue fever, with seasonal variations and uncertainties in the transmission rates. Assuming continuous measurement of the number of new infectives in the host population per unit time, a class of interval observers with estimate-dependent gain is constructed, and asymptotic error bounds are provided. The synthesis method is based on the search for a common linear Lyapunov function for monotone systems representing the evolution of the estimation errors.

Ensuring successful introduction of Wolbachia in natural populations of Aedes...FGV Brazil
The control of the spread of dengue fever by introduction of the intracellular parasitic bacterium Wolbachia in populations of the vector Aedes aegypti, is presently one of the most promising tools for eliminating dengue, in the absence of an efficient vaccine. The success of this operation requires locally careful planning to determine the adequate number of individuals carrying the wolbachia parasite that need to be introduced into the natural population. The introduced mosquitoes are expected to eventually replace the Wolbachia-free population and guarantee permanent protection against the transmission of dengue to human. In this study, we propose and analyze a model describing the fundamental aspects of the competition between mosquitoes carrying Wolbachia and mosquitoes free of the parasite. We then use feedback control techniques to devise an introduction protocol which is proved to guarantee that the population converges to a stable equilibrium where the totality of mosquitoes carry Wolbachia.

The resource curse reloaded: revisiting the Dutch disease with economic compl...FGV Brazil
This paper shows that the Dutch disease can be more formally characterised as low economic complexity using ECI-type indicators; there is a solid and robust inverse relationship between exports concentrating on natural resources and economic complexity as measured by complexity indicators for a database of 122 countries from 1963 to 2013. In a large majority of cases, oil answers for shares in excess of 50% of exports. In addition to empirical panel analysis, we address case studies concerned with Indonesia and Nigeria and introduce a brief review of the theoretical literature on the topic. Indonesia is considered in the literature as a good example in avoiding the negative effects of the Dutch disease, whereas Nigeria is taken as a bad example in terms of institutions and policies adopted during the seventies and eighties. The empirical results show that complexity analysis and Big Data may offer significant contributions to the still-current debate surrounding the Dutch disease.

The main purpose of this paper is to apply big-data and scale-free complex network techniques to the study of world trade, with a specific focus on the investigation of ECLA and structuralist ideas. A secondary objective is to illustrate the potentialities of the use of the new science of complex networks in economics, in what has been recently referred to as an econophysics research agenda. We work with a trade network of 101 countries and 762 products (SITC-4) which generated 1,756,224 trade links in 2013. The empirical results based on network analysis and computational methods reported here point in the direction of what ECLA economists used to argue; countries with higher income per capita concentrate in producing and exporting manufactured and complex goods at the center of the trade network; countries with lower income per capita specialize in producing and exporting non-complex commodities at the network’s periphery.

A dynamic Nelson-Siegel model with forward-looking indicators for the yield c...FGV Brazil
This paper proposes a Factor-Augmented Dynamic Nelson-Siegel (FADNS) model to predict the yield curve in the US that relies on a large data set of weekly financial and macroeconomic variables. The FADNS model significantly improves interest rate forecasts relative to the extant models in the literature. For longer horizons, it beats autoregressive alternatives, with a reduction in mean absolute error of up to 40%. For shorter horizons, it offers a good challenge to autoregressive forecasting models, outperforming them for the 7- and 10-year yields. The out-of-sample analysis shows that the good performance comes mostly from the forward-looking nature of the variables we employ. Including them reduces the mean absolute error in 5 basis points on average with respect to models that reflect only past macroeconomic events.

Improving on daily measures of price discoveryFGV Brazil
We formulate a continuous-time price discovery model in which the price discovery measure varies (stochastically) at daily frequency. We estimate daily measures of price discovery using a kernel-based OLS estimator instead of running separate daily VECM regressions as standard in the literature. We show that our estimator is not only consistent, but also outperforms the standard daily VECM in finite samples. We illustrate our theoretical findings by studying the price discovery process of 10 actively traded stocks in the U.S. from 2007 to 2013.

Disentangling the effect of private and public cash flows on firm valueFGV Brazil
This paper presents a simple model for dual-class stock shares, in which common shareholders receive both public and private cash flows (i.e. dividends and any private benefit of holding voting rights) and preferred shareholders only receive public cash flows (i.e. dividends). The dual-class premium is driven not only by the firm's ability to generate cash flows, but also by voting rights. We isolate these two effects in order to identify the role of voting rights on equity-holders' wealth. In particular, we employ a cointegrated VAR model to retrieve the impact of the voting rights value on cash flow rights. We finnd a negative relation between the value of the voting right and the preferred shareholders' wealth for Brazilian cross- listed firms. In addition, we examine the connection between the voting right value and market and firm specific risks.

Mandatory IFRS adoption in Brazil and firm valueFGV Brazil
Using diff-in-diff approaches and the propensity-score matching, this study focuses on firm-level Tobin´s q and Market-to-book outcomes for Brazilian firms who in 2008 were required by Law 11.638/07 to adopt the full International Financial Reporting Standards (IFRS) by 2010. Brazil’s tier-system of corporate governance standards for publicly-traded firms, its uniquely wholesale adoption of the IFRS, and the previously considerable gap between its national GAAP and IFRS readily lend the scenario to research, which thus far finds small or inconsistent results when focused on IFRS adoption-related outcomes in Europe and China. However, while these features recommend the transitioned Brazilian equity market to analysis, additional unique features, such as its small population size and its limited historical data -- of varied quality – increase the challenge in selecting a suitable empirical methodology. Using quarterly data from 2006-2011, control firms in the Nivel II and Novo Mercado tiers of Bovespa which already complied with higher quality accounting standards are matched to treatment firms in the Regular and Nivel I tiers with similar averaged values of size and sector. Our results suggest that there is a positive impact on Tobin´s q and Market-to-book for firms who are forced to adopt IFRS in Brazil. We can observe the same results when we consider all variables winsorized at 5% level. We also find a positive relation between the firm value (measured by Tobin´s q and Market-to-book) and net income. Firms with higher net income are more likely to have higher Tobin´s q and Market-tobook. In an opposite way, we find a negative relation among firm value, size, Ebit-to-sales, sales growth and PPE-to-sales. All results are statistically significant at 1% level. '

Dotcom bubble and underpricing: conjectures and evidenceFGV Brazil
This document presents conjectures about the causes of the dotcom bubble and high underpricing of IPOs during 1999-2000. It proposes two main conjectures: 1) The large inflow of high-growth IPOs affected expectations about long-term growth rates in the industry, feeding the price spiral in the stock market. 2) Some companies strategically underpriced their IPOs to avoid risks associated with distributing overvalued shares, as they needed continued access to capital markets for acquisitions or future funding rounds. The document provides evidence that the flow of high-growth IPOs explains returns in the NASDAQ index, and that characteristics like pre-IPO acquisitions can fully account for the high
Contingent judicial deference: theory and application to usury lawsFGV Brazil
Legislation that seems unreasonable to courts is less likely to be followed. Building on this premise, we propose a model and obtain two main results. First, the enactment of legislation prohibiting something raises the probability that courts will allow related things not expressly forbidden. In particular, the imposition of an interest rate ceiling can make it more likely that courts will validate contracts with interest rates below the legislated cap. Second, legal uncertainty is greater with legislation that commands little deference from courts than with legislation that commands none. We discuss examples of effects of legislated prohibitions (and, in particular, usury laws) that are consistent with the model.

Education quality and returns to schooling: evidence from migrants in BrazilFGV Brazil
We provide a new education quality index for states within a developing country using 2010 Brazilian data. This measure is constructed based on the notion that the financial returns obtained from an additional year of schooling can be
seen as being derived from the value that market forces assign to this education. We use migrant data to estimate returns to schooling of individuals who studied in different states but who work in the same labor market. We find very heterogeneous educational qualities across states: the poorest Brazilian region presents education quality levels that are approximately equal to one-third of the average of all other regions, a gap three times larger than the one suggested by standardized test scores. We compare our index with standardized test scores, educational outcome variables, and public expenditure per schooling stage at the state level, producing new evidence related to education in a large developing country. We conduct an education quality-adjusted development accounting exercise for Brazilian states and find that human capital accounts for 26%-31% of output per worker differences. Adjusting for quality increases human capital’s explanatory power by 60%.

We examine the impact of government equity ownership on the degree of internationalization of emerging market firms. Our analysis of 173 Brazilian publicly traded firms from 2002 to 2011 shows that the higher the equity held by the state through the state investment bank and the pension funds of SOEs and privatized SOEs, the higher the firm’s degree of internationalization. Firms in which the government shared control with families, and with both families and foreigners, had a higher degree of internationalization. Our findings underline the importance of the institutional context in explaining the internationalization of Brazilian firms.

Techno-government networks: Actor-Network Theory in electronic government res...FGV Brazil
The Actor-Network Theory (ANT) is a theoretical approach for the study of controversies associated with scientific discoveries and technological innovations through the networks of actors involved in such actions. This approach has generated studies in Information Systems (IS) since 1990, however few studies have examined the use of this approach in the e-government area. Thus, this paper aims to broaden the theoretical approaches on e-government, by presenting ANT as a theoretical framework for e-government studies via published empirical work. For this reason, the historical background of ANT is described, duly listing its theoretical and methodological premises. In addition to this, one presented ANT-based e-government works, in order to illustrate how ANT can be applied in empirical studies in this knowledge area.

This document discusses the agroecological social movement in Araponga, Minas Gerais, Brazil. It begins by providing context on agroecology as both a science and social movement that promotes sustainable farming practices as an alternative to industrial agriculture. It then discusses Paulo Freire's theories of emancipatory education and their influence on the Brazilian agroecological movement. Specifically, Freire advocated for education that develops critical consciousness and self-organization among oppressed groups. The document uses Freire's theories as a framework to analyze how the agroecological movement in Araponga formed through collective experiences and grassroots knowledge-sharing to strengthen autonomy and resistance to corporate agriculture models.
Condemning corruption while condoning inefficiency: an experimental investiga...FGV Brazil
This article reports results from an economic experiment that investigates to what extent voters punish corruption and waste in elections. While both are responsible for a loss of welfare for voters, they are not necessarily perceived as equally immoral. The empirical literature in political agency has not yet dealt with these two dimensions that determine voters’ choices. Our results suggest that morality and norms are indeed crucial for a superior voting equilibrium in systems with heterogeneous politicians: while corruption is always punished, self-interest alone – in the absence of norms – leads to the acceptance and perpetuation of waste and social losses.

Coalition management under divided/unified governmentFGV Brazil
"If the opposite of pro is con, then the opposite of progress must be the Congress”, says a popular joke about the divided government in the US two-party presidential regime. Divided government occurs when different political parties control different branches of government. By this arithmetic definition, however, divided government almost always takes place in multiparty presidential regimes, given that the party of the president rarely obtains solely the majority of seats in Congress. In order to govern and pass legislation, a minority president has to build and sustain post-electoral coalitions in multiparty settings. The received wisdom on multiparty presidential regime is that constitutional and agenda-setting powers and presidential preferences would be the key determinants for a successful minority government. In addition to those aspects, however, this paper claims that the degree of congruence between the preference of the presidential coalition and the preference of the floor of the Congress is the crucial ingredient. That is, regardless of presidential preferences or characteristics, the higher the preference incongruence between the president’s coalition and the floor, the more difficult would be the coalition management and the higher the probability that the Congress would work as the opposite of progress. It is, in fact, the equivalent functional of divided government in multiparty presidential settings. This paper explores conceptually and empirically the effect of the distance of preferences between the coalition and the floor in the multiparty presidential regimes in Latin America.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

ABSTRACT
As an approach to determining the degree of integration of the Brazilian economy, this
paper seeks to test the explanatory power of the Goldman Sachs Model for the expected
returns by a foreign investor in the Brazilian market during the past eleven years (2004-
2014). Using data for the stocks of 57 of the most actively traded firms at the
BM&FBovespa, it begins by testing directly the degree of integration of the Brazilian
economy during this period, in an attempt to better understand the context in which the
model has been used. In sequence, in an indirect test of the Goldman Sachs model, the
risk factor betas (market risk and country risk) of the sample stocks were estimated and
a panel regression of expected stock returns on these betas was performed. It was found
that country risk is not a statistically significant explanation of expected returns,
indicating that it is being added in an ad hoc fashion by market practitioners to their
cost of equity calculations. Thus, although there is evidence of a positive and significant
relationship between systematic risk and return, the results for country risk demonstrate
that the Goldman Sachs Model was not a satisfactory explanation of expected returns in
the Brazilian market in the past eleven years, leading us to question the validity of its
application in practice. By adding a size premium factor to the model, there is evidence
of a negative and significant relationship between companies’ size and return, although
country risk remains not satisfactory to explain stock expected returns.
Keywords: Goldman Sachs Model; Degree of Market Integration; Country Risk;
Systematic Risk.

1. Introduction
It certainly goes without saying how crucial the estimation of a firm’s cost of equity is,
especially for practical purposes – for equity and firm valuation in mergers and
acquisitions, security analysis for investment recommendation purposes, for the
determination of value creation by managers, and various other essential corporate
finance decisions.
The starting point in most of the current practice is to begin with the Sharpe-Lintner-
Mossin (SLM) version of the capital asset pricing model (CAPM), in which values for
the rate of return on a proxy for the risk free asset and a premium for exposure to market
portfolio risk would be sufficient, including an estimate for the asset’s degree of
exposure (beta).
However, in many cases practitioners add premiums for other risk factors, for at least
two reasons: (a) they do not believe the SLM version of the CAPM is valid, as indicated
by the Fama and French (1992) results, or (b) they feel the need to adjust the SLM
version of the CAPM for conditions in the specific market in which an investment is to
be evaluated. For the first reason, a premium for the companies’ size is frequently added
(following the conclusions of Fama and French. 1992). Meanwhile, one example of the
second reason is the addition of a premium for country risk, in the belief that the
country’s market is not sufficiently integrated into the world market, and that this
country risk would not be diversifiable, from the view point of an international investor.
This procedure is reported in a survey by Keck et al. (1998).
The so-called Goldman Sachs model, attributed to Mariscal and Lee (1993), consists in
the use of proxies from a developed, integrated market, such as that of the United
States, for both the risk free asset (e.g., US Treasury bonds) and the market portfolio
(e.g., the S&P500 index). With such data, a US investor would evaluate investments in
her domestic market. However, if the investor were evaluating an investment
opportunity, say, in Brazil, the Goldman Sachs model would recommend the addition of
a premium for Brazil risk (e.g., the EMBI+ Brazil index, measuring the spread between
the yields on Brazilian sovereign bonds and US Treasury bonds.
Even though it is not clear that the evaluation is being performed for the benefit of an
international investor, local market evaluations make frequent use of the Goldman
Sachs model. In a survey of 52 valuation reports for going-private purchase offers, as
required by the corresponding Brazilian regulation, covering the 2008-2013 period,
5. 3
Sanvicente (2014) finds that in all reports an adjustment is made for country risk, using,
in over 50% of the cases, the EMBI+ published by JP Morgan. In turn, the risk free
asset is proxied by 10- or 30-year US Treasury bonds, and the market portfolio is
represented by the S&P500 index, the market risk premium being measured with
average historical returns. Hence, it can be claimed that at least 50% of this particular
application of cost-of-equity estimation methods make explicit use of the Goldman
Sachs model.
The objective of the present paper is, therefore, to determine the empirical relevance of
the Goldman Sachs model in the estimation of the cost of equity for the Brazilian
market. This is accomplished both directly, through a test of the significance of a
country risk premium for equity expected returns, and indirectly, by testing whether the
Brazilian market is partially or fully integrated into the world market, using the
incremental risk measure proposed by Keck et al. (1998). The paper also tests the
significance of the size premium in a multifactor model, as in Fama and French (1992)
for the equities’ expected returns.
The paper is structured as follows: following the Introduction, a discussion of the
relevant literature is presented, the methodology used for both tests is explained, data
definitions and sources are provided, results are displayed, and the paper then
concludes.
2. Review of literature
One of the basic issues in the choice of a model as a basis for the estimation of cost of
equity and discount rates in general, when dealing with investments outside the
domestic economy, is the perception of how integrated the particular overseas market is,
and whether one should adjust a basic model for non-diversifiable risks, such as country
risk, or similar manifestations of emerging market risks, such as political or currency
risk.
It is reported in the literature that investors tend to adjust their valuation methodology as
a function of their perception of how much the particular market is integrated into the
world market (KECK et al., 1998). Fuenzalida and Mongrut (2010), Stulz (1999) and
Harvey (2005) emphasize that it is possible to construct a parallel between cost-of-
equity computation methods and a market’s degree of integration.
6. 4
For fully integrated markets, for example, Stulz (1999) argues that firms should adopt a
discount rate treating them as part of the world stock portfolio. Global portfolio
diversification would then lead to risk reduction and hence to the lowering of required
returns.
However, investors in not fully integrated markets would have their diversification
possibilities reduced. For Mishra and O’Brien (2001), asset pricing models in emerging
markets divide risks in such markets into two components: a systematic risk component,
captured by asset betas, and a non-systematic risk component, whose inclusion in such
models is subject to much debate. If markets were fully integrated, for example, country
risk would be irrelevant in the estimation of the cost of equity, since it could be
eliminated via diversification (HARVEY, 2005).
In integrated financial markets, home investors can freely invest in foreign assets, and
international investors can invest in domestic assets (BEKAERT et al., 2003). Hence,
assets with identical risks (involving, for example, cash flow and leverage
characteristics) would command identical expected returns, regardless of the market in
which they are traded.
With the opening up of several emerging markets starting in the 1980’s, the interest in
the effects of capital market integration on the economy as a whole has expanded.
In an integrated market, an asset’s expected returns can be explained by the covariance
with world market returns (BEKAERT et al. 2002). However, in a segmented or
partially integrated market, the covariance with a global factor may have low
explanatory power for expected returns (BEKAERT and HARVEY, 1995).
According to Bekaert et al. (2002), Henry (2002), Bekaert and Harvey (1995), and
Errunza and Miller (2000), when an economy moves from a segmented market regime
to that of an integrated market, expected returns, return volatilities and correlations with
major global market indices are affected in that economy, and it is apparent that market
integration is key to the present discussion.
Henry (2002) observes that a country’s market index, when the economy is in a process
of liberalization, achieves abnormal returns of approximately 3.3% on a monthly basis
(in real US dollar terms) for eight months since the inception of liberalization policies.
This result is consistent with the contention that liberalization policies help to lower the
cost of equity level in a given country, since international risk diversification now
becomes possible (STULZ, 1999).
7. 5
Bekaert et al. (2002) discuss the effects of financial market integration using a broad set
of macroeconomic indicators. Using data for 20 liberalizing emerging markets, they
classify their variables into five groups: (a) changes in dividend yields; (b) market
liquidity (measured by the ratio between market capitalization and GDP); (c) capital
inflows (measured by the flow of US investments divided by total market
capitalization); (d) stock dispersion in a particular market and correlation with world
markets; and (e) local economic environment (volatility of exchange and inflation rates
and the ratio between exports, imports to GDP). They conclude that integration is
accompanied by an expanding and more liquid capital market, in addition to an increase
in return volatility and in correlations with global markets.
Errunza and Miller (2000), Bekaert and Harvey (1999), Bekaert et al. (2002) and Henry
(2002) state that increased integration leads to a reduction in the cost of equity, an
improvement in the country’s credit rating, as well as currency appreciation and
economic growth thanks to increasing investment.
Concerning the cost of equity, Bekaert et al. (2002) and Stulz (1995) posit that, once
access is given to foreign investors to the local market, portfolio diversification
opportunities produce higher domestic asset prices, which is equivalent to lower
required returns.
It should pointed out, however, that many factors may be compatible with a market’s
liberalization process, without leading to the effective and immediate integration of a
country’s economy. Bekaert et al. (2002), for example, indicate that economic growth or
currency appreciation, usually mentioned as the consequence of higher market
integration, are not always the consequence of liberalization measures. This complicates
controlling for the variables with which one assesses a market’s degree of integration.
According to Solnik (1974), six main factors can cause market segmentation: (a) legal
and regulatory constraints; (b) transactions costs; (c) discriminatory taxation; (d)
political risk; (e) psychological barriers; and (f) foreign exchange risks. However, Keck
et al. (1998) point out that, for one to state that a market is integrated it is not sufficient
to observe the above enumerated factors.
Such factors may cause a given market to become riskier, but do not necessarily require
a multifactor model for the cost of equity, or even a new single factor model. Keck et al.
(1998) argue that a revision in the cost of equity model would be justified only if the
same risk were priced differently, or if different risks were priced.
8. 6
The adoption of a distinct model for a particular national market, in contrast with an
international and fully integrated market would have to be justified by how much they
differ in terms of their integration to the world market, possibly because the particular
national market imposes barriers to investment by foreigners (KECK et al. 1998).
Assuming that a Global CAPM were to describe precisely how assets are priced in the
world market, the expected risk premium in a global stock portfolio would be identical
for all investors, regardless of where they happened to be located geographically. Stulz
(1999) argues that a Global CAPM should be used for computing assets’ capitalization
rates, since in most markets the cost of equity is globally, and not locally determined.
However, Keck et al. (1998) argue that two hypothetical firms, with identical products,
cash flows and capital structures, but located in different national markets, one fully
integrated and the other partially integrated to the global economy, should have
different expected returns.
The firm based in the partially integrated market, from an international investor’s
viewpoint, faces a risk pricing process which is distinct from that faced by the firm
based in the fully integrated market. Thus, when once compares the expected returns for
the two firms, their cost of equity models should be as follows.
For the firm located in a fully integrated market (Home market):
fGLhGHLfH rrEbbrrE )()()( (1)
where bHL is the slope of the regression of the integrated firm’s returns against the
returns on its home country’s index. In turn, bLhG is the slope of the regression of the
fully integrated market’s index against the returns on a global market index.
For the firm located in a partially integrated market (Away market):
fGLaGALfA rrEbbrrE )()()( (2)
where bAL is the slope of the regression of the partially integrated firm’s returns against
the returns on its own local market index, whereas bLaG is the slope of the regression of
the local market index returns against those of the global market index.
If both markets were fully integrated into the world market, the expected returns for
both firms would be identical, so that (bHL x bLhg) would be equal to (bAL x bLaG)
9. 7
(STULZ, 1999). For the firm located in the Away market, when it is not fully
integrated, the cost of equity would be given by:
fGaLaGALfA rrEbbbrrE )()()( (3)
with ba indicating the incremental risk, according to Keck et al. (1998), associated with
the fraction of the Away market’s returns that co-vary with the global market, but not
with the local market. Thus, risk in such a market is priced differently, from the
international investor’s viewpoint.
Asset pricing models may be classified into three main categories: segmented, fully
integrated, and partially integrated markets (BEKAERT and HARVEY, 1995).
According to Pereiro (1999), Stulz (1999) and Fuenzalida and Mongrut (2010), it is
possible to associate cost-of-equity estimation methods and a market’s degree of
integration. This association is illustrated in Table 1.

Table 1 shows that, as pointed out by Keck et al. (1998), with greater uncertainty and
market complexity in markets not fully integrated investors tend to resort to multifactor
models, such as the Goldman Sachs version, and to the addition of ad hoc risk
premiums.
The basic approach to estimating the cost of equity is the CAPM developed by Sharpe
(1964), Lintner (1965) and Mossin (1966). It says that an asset’s expected return is a
10. 8
linear function of the risk free rate, the asset’s systematic risk and the market portfolio’s
risk premium. The CAPM characterizes the asset’s systematic risk as its contribution
(beta) to the variance of returns on a diversified market portfolio.
Black et al. (1972) and Fama and MacBeth (1973) find, as predicted by the CAPM, that
stock returns and their betas are positively associated in the pre-1969 period.
However, later tests of the CAPM lead to questioning the model’s applicability. Fama
and French (1992) find that the positive association between betas and expected returns
disappears in the 1963-1990 period. In contrast, they find significant association
between returns and size, leverage, earnings/price and book-to- market ratio. In the case
of size (whose significance is tested in this paper), Fama and French (1992) assign, for
each year, stocks into 12 portfolios (including all New York Stock Exchange stocks that
have reported price series) using the ranked values of market cap. The authors find that
average returns of smaller stocks are too high given their beta estimates and average
returns of larger stocks are too low. In addition, Fama and French (1992) find that there
is a negative and statistically significant relation between size and average returns.
Similarly, Harvey (1995) does not find a significant association between returns and
betas measured against a global portfolio for over 800 firms in 20 emerging markets.
This could be explained by the lack of integration of those markets into the global
economy, making the use of a global beta unfeasible, by the assumption that betas are
constant over time, or by the fact that emerging markets are more susceptible to local
than to global factors. This is evidence that asset pricing models that are predicated on
full market integration would not be able to explain expected returns in partially
integrated markets (HARVEY, 1995).
In contrast with Harvey (1995), Pereiro (1999) argues that the increasing integration and
free intermarket capital flows have allowed investors from any part of the world to enter
and exit any given market at minimal transactions costs.
Stulz (1999) argues that the removal of barriers to the free flow of capital leads to lower
risk premiums in emerging markets, since risks can now be globally diversified.
In reality, emerging markets, such as those in South America, have undergone
significant development as a result of liberalization programs that have encouraged
international investment (STULZ, 1999).
Hence, for the firms with access to the global stock market, the use of the Sharpe-
Lintner-Mossin CAPM that presumes market segmentation (BEKAERT and HARVEY,
11. 9
1995) will tend to overestimate the cost of equity, since diversifiable risks in a local
market investment could now be diversified internationally (STULZ, 1999).
Thus, Stulz (1999) proposes a Global CAPM approach, in which any investment is part
of a global portfolio, using a global market index such as the MSCI World Index as a
proxy for the market portfolio.
However, according to Harvey (1995), when the Global CAPM is used for stocks in
emerging markets, and a regression is run against the global market proxy, such as the
MSCI World Index, betas are negative or close to zero.
Given the low correlations between many emerging markets and developed markets, in
addition to the preponderance of local factors as explanations for expected returns,
Harvey (1995) states that the Global CAPM should not be used when investments in not
fully integrated markets are contemplated. He emphasizes that, when one uses an asset
pricing method based on the Global CAPM, as in Stulz (1999), one is assuming that the
market examined is fully integrated into the world market. The rejection of such a
global model, therefore, could be explained by the failure of the full market integration
assumption.
One adaptation that is widely used by many investment banks and consulting firms is
the Goldman Sachs Model, developed by Mariscal and Lee (1993). It is one of the first
models to assume partial market integration, especially in emerging markets
(FUENZALIDA and MONGRUT, 2010).
In the Goldman Sachs model, a regression is run between stock returns and returns on
the S&P 500. The betas thus estimated are multiplied by the risk premium on the S&P
500 index. Finally, a country risk premium is added, in an ad hoc fashion, to correct for
an allegedly low cost of equity. Such a premium can be based on the Emerging Markets
Bond Index Plus (EMBI+), computed by JP Morgan, measuring the spread between
yields on sovereign debt instruments issued by the country of interest, traded overseas,
and yields on US Treasury securities with similar time to maturity (ZENNER et al.
2008).
According to Fama and MacBeth (1973) and Sanvicente (2014), the Sharpe-Lintner-
Mossin model presupposes the use of a single risk factor in the determination of an
asset’s expected returns, which is proportional to the quantity of non-diversifiable (beta)
risk of the asset. Thus, the inclusion of any premium beyond that of the market portfolio
would be an ad hoc procedure without theoretical basis. Fama and MacBeth (1973), for
12. 10
example, determined that risk measures other than beta do not contribute to the
construction of an efficient portfolio.
Sanvicente (2014) tested the significance of country risk for observed returns, using a
sample of 204 firms in the Brazilian market. Observing that the performance of the local
proxy for the market portfolio is already affected by country risk, the addition of a
country risk premium would then be unnecessary, a result that would provide support
for the use of Local CAPM when assessing the cost of equity in Brazil, even from the
viewpoint of international investors.
When testing for the relevance of various common risk factors, a measure of asset
expected returns is required. As proposed in Harris et al. (2003), Sanvicente and
Minardi (1999), and Sanvicente and Carvalho (2013), expected returns, as a measure of
an investment’s opportunity cost, is best extracted from the corresponding asset’s
intrinsic value, defined as the present value of all payments to the investor, including
dividends and terminal selling price, discounted at a risk-adjusted interest rate. In
equilibrium, current market price would reflect intrinsic value estimates. Assuming that
dividends grow perpetually at a constant rate, the stock price may be written as:
)/()1(0 grgDP (4)
Where:
D1 = D0(1 + g) = next period’s expected dividend
r = rate of return required by the investor
g = rate of growth of dividends
Proposed by Gordon (1959), the formula is known as Constant Growth Discounted
Dividend Model, that allows us to extract the stock’s required rate of return (r) from a
security traded at its intrinsic value as:
r = (D1/P) + g = dividend yield + expected dividend (and earnings) growth
Fama and French (2002) favor the use of dividend and expected growth fundamentals in
the estimation of expected returns, as opposed to the use of average historical returns as
a proxy for expected returns, adding that the standard deviation of expected market risk
13. 11
premiums obtained with the Discounted Dividend Model is less than half the standard
deviation resulting from the use of historical returns.
Elton (1999) claims that the use of historical returns as a proxy for expected returns is
based on the belief that informational surprises that are capable of altering expectations
would tend to cancel each other over time and, therefore, average historical returns
would be an unbiased estimate of expected returns. However, he shows that, with the
possibility of large and persistent surprises, an inertial effect may result. Their
cumulative effect could be sufficiently large to invalidate the use of historical returns as
proxies for expected returns.
According to Keck et al. (1998), global market integration implies that investors, be
they local or international, should use Global CAPM to estimate the cost of equity. For
those investors in relatively segmented markets, however, the use of Local CAPM
would be justified.
However, even professionals that adopt the Sharpe-Lintner-Mossin version of the
CAPM differ in their approach when dealing with overseas investments.
In a survey involving 2,700 University of Chicago students, Keck et al. (1998) indicate
that increasing market uncertainty and complexity appear to led investors to resort to
heuristic procedures when valuing their investments, such as, for example, the choice of
discount rate estimation method as a function of their perception how integrated the
market is.
Contrasting with one of the central results of the CAPM, that beta is sufficient for
pricing an asset’s risks, most survey respondents said that they used multifactor models,
adding political, credit and currency exchange risk premiums to the discount rate. The
uncertainty associated with a perception of less than complete market integration, in
certain instances, also led to the use of international (e.g., the S&P500) market proxies,
to the detriment of local market indexes.
The results in Sanvicente (2014), as in Keck et al. (1998) and Harvey (2005), are
evidence of the use of heuristic procedures when there is greater uncertainty and
complexity involving the emerging market invested in.
3. Methodology
The present paper initially determines the level of integration of the Brazilian market in
the 2004-2014 period, with the help of the Keck et al. (1998) methodology.
14. 12
Subsequently, the paper tests the Goldman Sachs model in terms of its prediction of
how expected returns are determined. Both the full period (2004-2014) and two five-
year sub-periods (2004-2008 and 2009-2014) are considered. Finally, the paper tests a
multifactor model by adding to the Goldman Sachs model factors a size premium, as in
Fama and French (1992).
Elton et al. (2006) state that, even though there exist methods to test the CAPM and
other expected return models empirically, more robust tests involve a two-stage
procedure. In the first stage, time series regressions are used for estimating betas for the
various risk factors contemplated; the second stage consists in using such estimated
betas as predictors in cross section regressions.
Therefore, in accordance with Harris et al. (2003) and Elton et al. (2006), the paper first
calculates betas for the risk factors considered, and then regresses expected returns
against the first-stage betas.
Expected returns, as in Fama and French (2002), Sanvicente and Minardi (1999) and
Harris et al. (2003), are computed with the Discounted Dividend Model.
The test proposed by Keck et al. (1998) identifies the incremental risk, interpreted as a
proxy for market integration, on the basis of the regression betas in two distinct
scenarios: in the first scenario, it is assumed that a particular firm is located in an
integrated market, and in the second one used the market in which it is in fact located
(Brazil, in this case).
The proxy chosen for an integrated market was the United States, and the market
portfolio was represented by the S&P 500. For Brazil, the market proxy was the IBrX
100 index.
Finally, for a global market portfolio, the proxy used was the MSCI World Index.
Given the sample selection procedure for each year, betas were first estimated, with
historical excess returns over a 60-month period, provided at least 36 months were
available. Thus, two betas are calculated for each firm: one for the integrated market
(US), and the other for the Brazilian market.
The incremental risk measure (ba), proposed by Keck et al. (1998), was assessed for
each sample year and for the full 2004-2014 period, resulting in annual and full-period
averages. For each of those results a one-tail test of the null hypothesis of a zero mean
was performed, against the alternative hypothesis that the incremental risk measure is
positive, indicating less than full integration of the Brazilian market.
15. 13
As for testing the Goldman Sachs model, initially stocks’ excess returns were regressed
against S&P 500 excess returns and the EMBI+ Brazil series to obtain estimates for
betas according to the Goldman Sachs model, for each year. Each regression used the
previous 60 months of data, when available.
Subsequently, the estimated betas were used as explanatory variables in panel data
regressions. Since data were not available for all sample firms in every year, an
unbalanced panel was used.1
The analysis was performed for three periods: 2004-2014
(the full sample period), 2004-2008, 2009-2014, in an attempt to determine the impact
of the 2008-2009 financial crisis on the relevance of the Goldman Sachs model.
Panel data estimation was chosen in order to account for the possibility of correlation
between regressors and the error term. Even though the Hausman test did not reject the
random effects model as a null hypothesis, the fixed effects model was used.
Rejection of the null hypothesis in the Hausman test indicates that the main assumption
of the random effects model, that is, that the unobserved effect is not correlated with the
explanatory variables is not true. This means that the fixed effects estimator should be
used. However, even when the Hausman test fails to reject the null hypothesis, it is
possible to use the fixed effects model. In this case, the estimator is consistent, but it is
less efficient than the random effects estimator.
Furthermore, the paper tested the significance of a multifactor model that comprises
both the country risk premium factor (as in the Goldman Sachs Model), and the size
premium factor, as in Fama and French (1992). For the analysis of the size premium,
the small minus big factor (SMB) provided by Nefin Center at the Department of
Economics, University of São Paulo, was used. The SMB factor is the return of a
portfolio long on stocks with low market cap (small) and short on stocks with high
market cap (big). Every January of each year, the eligible stocks are sorted according to
their previous December market cap, and separated into 3 quantiles. The SMB factor is
the return of the small stock portfolio minus the return of the big stock portfolio. These
premiums were used, as the country risk premium, in a time series regression. Stocks’
excess returns were regressed against S&P 500 excess returns, the EMBI+ Brazil series
and SMB factor to obtain estimates for betas for each year. Subsequently, the estimated
betas were used as explanatory variables in panel data regressions.
1
Since the sample size in each year was not large enough, individual stock betas were used, and not
portfolios, as was the case in Harris et al. (2003). According to Claessens et al. (1995), the use of panel
data and estimation with the fixed effects model, because the data are centered are around their means,
tends to attenuate the estimation bias caused by the use of individual stocks.

4. Data and data sources
In the present paper, the following data are used:
a) Monthly log returns of all stocks included in the IBrX 100 index2
, from
December 1999 to December 2014.
b) Annual dividends, in US dollars, as well as return on equity and payout ratios
for all stocks included in the IBrX100 index, for the 2004-2014 period, as
required by the calculation of expected returns according to the Dividend
Discount Model.
c) Monthly yields to maturity of 10-year US Treasury Bonds, as a proxy for the
risk free rate faced by international investors in emerging markets, as in Harris et
al. (2003).
d) Monthly values of EMBI+ Brazil, a measure of the country’s default risk on its
sovereign debt, and the commonly used instrument for country risk.
e) Monthly returns on the S&P500, as a proxy for the market portfolio in the
Goldman Sachs model, from December 1999 to December 2014.
f) Monthly returns on the MSCI World Index, as a proxy for the global market
portfolio, also for the period from December 1999 to December 2014.
g) Monthly returns on the IBrX 100, as a proxy for the local market portfolio, used
in the market integration tests, and also from December 1999 to December 2014.
h) Small minus big factor (SMB) provided by Nefin Center at the Department of
Economics, University of São Paulo, for each year.
Stock prices were collected in the Economática database, converted into US dollars and
adjusted for dividends and stock splits. Annualized dividends, as well as values for
return on equity and payout ratios were obtained in the IQ Capital Markets database.
Yields to maturity for 10-year US Treasury Bonds and the historical series for the
S&P500, MSCI World, EMBI+ Brazil and the IBrX 100 indexes were provided by
Bloomberg.

This is a capitalization-weighted index computed by the BM&FBovespa for the Brazilian market. It
includes the 100 securities with the largest share of trading volume in the preceding 12 months. The
capitalization weights are based on the securities’ free float.
17. 15
The list of stocks considered in each year was defined according to the composition of
IBrX 100 portfolio as of January of each year. The portfolio is rebalanced once a year as
a function of each stock’s liquidity and the market value of its free float.
The choice of the IBrX 100 index, instead of the Ibovespa, was based on the fact that in
the former, market capitalization is used as a source of stock weights in the portfolio,
instead of its share in total trading volume.
The initial sample was adjusted for the following criteria:
a) Firms for which dividend, return on equity or payout ratio data were not
available in a given year, were excluded from that year’s sample data.
b) Stocks without complete 12-month price series for a particular year were
excluded from that year’s sample data.
c) Stocks with less than 36 months of historical price series were ignored, since
beta estimation required the use of at least 36 months of price data.
d) Only the most actively traded security for a given firm was used, when at least
two security classes for the firm were contained in the index portfolio.
The effect was the reduction to the use of data for 57 firms, on average, over the 11-year
period. The total number of observations was 628 firm-years.
5. Results
5.1. Incremental risk
Using the methodology described in Keck et al. (1998), incremental risk was calculated
for each sample firm in each year. It should be recalled that incremental risk was
estimated by the difference between the betas calculated for each sample firm, in two
different markets: the US, integrated market, and the Brazilian market, for which the
degree of integration is being assessed. The averages of the incremental risk measure
were calculated across firms for each sample year and for the full period. The
corresponding descriptive statistics are presented in Table 2 for the full 11-year period.

The results indicate that, for the full period, there is no evidence for rejecting the null
hypothesis of full integration. When examined on an annual basis, it is observed that the
same result is obtained for 8 of the 11 years, with rejection clearly occurring in the
2008-2009 period encompassing the financial crisis.
5.2. Goldman Sachs model
For testing purposes, the following specification was used:
Rit=γ0+γ1β1it+γ2β2t+γ3β3it+ηit (5)
Where:
Rit = excess expected returns for stock i in year t.
β1it = estimated beta for market risk, for stock i in year t, by multiple regression of past
observed excess returns against excess returns on the market index (the S&P 500) and
the country risk indicator (EMBI+ Brazil).
β2it = estimated beta for country risk, for stock i in year t, resulting from the same
multiple regression with the stock’s excess expected returns, the excess returns on the
proxy for the market portfolio (the S&P 500), and the country risk index.
The necessary calculation of expected returns for individual stock using the Discounted
Dividend Model, which are used as the dependent variable in regression equation (5),
generated the following results over the 2004-2014 period.

Figure 1: Average stock expected returns in the Brazilian market, 2004-2014.
Figure 1 indicates that, over the period, there was a reduction in the average cost of
equity in the Brazilian market, with the exception of a slight increase in 2008, as would
be expected as a reflection of the financial crisis. As was pointed out in the review of
literature, a reduction in cost of equity, equivalent to an increase in security prices,
accompanies an increase in a particular market’s integration into the world market.
The Goldman Sachs model will be validated if (a) we cannot reject the null hypothesis
that γ0 is equal to zero; (b) we reject the null hypotheses that γ1 and γ2 are equal to zero,
against the alternative that they are positive. In particular, we are interested in the
significance of the country risk premium (positive γ2), since this is how the Goldman
Sachs model differs from both Global and Local CAPM. Table 4 summarizes the
hypotheses involved in our tests.

Although the Hausman test did not lead to the rejection of the null hypothesis that the
random effects model would be appropriate (chi-square = 2.8196, p-value = 0.4026),
equation (5) was estimated with the fixed effects model. According to Wooldridge

(2008), the assumption that unobserved effects are uncorrelated with the explanatory
variables is an exception to the rule, and for this reason the fixed effects model is widely
used. In addition, for time-varying explanatory variables, the random effects model is
recommended only when the sample is randomly selected. This is not the case in the
present paper, in which, for every year, the stocks selected were those included in the
IBrX 100 index. Still, even when the Hausman test does not reject the null hypothesis,
the fixed effects estimator is still consistent. Robust standard errors were used, and
Table 5 presents the results for the full period.

The results displayed in Table 5 indicate that: (a) the significant intercept suggests that
additional factors may be required for explaining expected returns, or that the risk free
rate is not adequately measured, as was the case in Fama and MacBeth (1973); (b) the
hypothesis that market risk is relevant is not rejected, there being a positive market risk
premium in expected returns; (c) the main contribution of the Goldman Sachs model,
with the inclusion of a country risk premium, does not seem to be appropriate, since no
significant premium was detected. As pointed out by Harvey (2005), in a fully
integrated market, as the results of our tests on incremental risk seem to indicate is the
Brazilian case, country risk premium would be irrelevant, since it could be diversified
away.

5.2.2. Results for the 2004-2008 and 2009-2014 sub-periods
In an attempt to ascertain the impact of the 2008-2009 financial crisis, we analyze our
data for two 5-year sub-periods, before and during the financial crisis versus after the
crisis. Table 6 displays the results obtained for the two sub-periods.

The sub-period results show that the support for rejecting the null of no market risk
premium is basically found in the 2009-2014 period. The results for the relevance of a
country risk premium, if anything, are even more unfavorable in the latter period.

5.3.Including the size premium in a multifactor model
For testing purposes, the following specification was used:
Rit=γ0+γ1β1it+γ2β2t+γ3β3it+ηit (6)
Where:
Rit = excess expected returns for stock i in year t.
β1it = estimated beta for market risk, for stock i in year t, by multiple regression of past
observed excess returns against excess returns on the market index (the S&P 500), the
country risk indicator (EMBI+ Brazil) and the size premium.
β2it = estimated beta for country risk, for stock i in year t, resulting from the same
multiple regression with the stock’s excess expected returns, the excess returns on the
proxy for the market portfolio (the S&P 500), the country risk index and the size
premium.
β3it = estimated beta for size risk, for stock i in year t, resulting from the multiple
regression with the stock’s excess expected returns, the excess returns on the proxy for
the market portfolio (the S&P 500), the country risk index and the size premium.
The necessary calculation of expected returns for individual stock using the Discounted
Dividend Model, which are used as the dependent variable in regression equation (6),
generated the following results over the 2004-2014 period.
The multifactor model will be validated if (a) we cannot reject the null hypothesis that
γ0 is equal to zero; (b) we reject the null hypotheses that γ1, γ2 and γ3 are equal to zero,
against the alternative that they are positive. Table 7 summarizes the hypotheses
involved in our tests.

Although the Hausman test did not lead to the rejection of the null hypothesis that the
random effects model would be appropriate (chi-square = 1,1749, p-value = 0.5557),
equation (6) was estimated with the fixed effects model. Robust standard errors were
used, and Table 8 presents the results for the full period.

The results displayed in Table 8 indicate that: (a) the significant intercept suggests that
additional factors may be required for explaining expected returns, or that the risk free
rate is not adequately measured, as was the case in Fama and MacBeth (1973); (b) the
hypothesis that market risk is relevant is not rejected, there being a positive market risk
premium in expected returns; (c) the main contribution of the Goldman Sachs model,
with the inclusion of a country risk premium, does not seem to be appropriate, since no
significant premium was detected. As pointed out by Harvey (2005), in a fully
integrated market, as the results of our tests on incremental risk seem to indicate is the
Brazilian case, country risk premium would be irrelevant, since it could be diversified
away; (d) the hypothesis that size premium is relevant is not rejected, indicating a
negative and significant relationship between the companies’ size and the expected
return, as was the case in Fama and French (1992).
6. Conclusion
This paper is concerned with determining the appropriateness of the widely used
Goldman Sachs model for the setting of cost of equity in the Brazilian market. Since the
model is predicated on the assumption that such a market is not fully integrated to the
25. 23
world market, it includes a premium for country risk. That type of risk would be
diversifiable, hence, not priced, if the market were fully integrated.
Besides testing the model’s implication that the country risk premium is positive and
significant, in addition to a premium for market risk proxied by an international index,
to reflect how the model is used in practice, the paper tests the significance of a direct
measure of market integration, as developed by Keck et al. (1998).
In contrast with previous attempts at testing some version of the CAPM, such as Fama
and French (1992), this paper uses expected excess returns implicit in current stock
market prices, following Harris et al. (2003).
Both analyses, using annual data for more than 50 firms in the Brazilian market over the
2004-2014 period, lead to negative conclusions regarding the relevance of the Goldman
Sachs model. If anything, the results point to the validity of using the S&P 500 index as
a proxy for market risk in integrated markets. The results also indicate that the estimated
intercept in our version of a two-factor model is positive and significant, suggesting the
need for including other risk factors – possibly those empirically determined by Fama
and French (1992) – for Brazilian stocks, an avenue for future study. By the inclusion of
a third factor (size premium), as in Fama and French (1992), the significance of the
model was also tested, indicating that size premium has a negative and significant
relationship with expected returns, albeit not implying the validity of the multifactor
model (intercept continues positive and significant and country risk premium is not
statistically significant).
Finally, competing explanations, such as Global CAPM and Local CAPM could also be
considered. Since both the S&P500 and the local market index (Ibovespa) are highly
correlated with the MSCI World Index, it is likely that both would be appropriate
predictors of expected Brazilian stock returns. It is at least clear that the Brazilian
market is sufficiently integrated in order to render the use of the Goldman Sachs invalid.
