Return Decomposition
By Long Chen and Xinlei Zhao
Presentation by Michael-Paul James
Directly modeling discount rate news and backing out cash flow news
adds residual news to the latter
○ The method has led to erroneous conclusions:
■ Larger relative DR variance
■ Value stocks earn higher returns due to higher βCF
■ βCF is more important than total βtotal
○ DR news cannot be accurately estimated (low predictive power)
and backed out CF news inherits large misspecification error of DR
○ Modeled Treasury bonds reveals higher CF variance with no real CF
risk
○ Minor changes in predictive variables produce opposite results
Directly modeling cash flow news, discount rate news, and residual
○ Value firms have both lower modeled CF betas and DR betas, but
higher residual betas, indicating that the results in the current
literature are driven by the residual news.
This document provides a summary of information for protecting various types of electrical equipment. It discusses transformer protection schemes and failure statistics. The author is George Rockefeller, an expert in protective relaying with extensive experience working for utilities and as a consultant. The guide focuses on applying protective relays to transformers and emphasizes protection principles over detailed settings. It discusses common protection devices, provides an example protection scheme, and identifies references for additional information.
The document discusses four topics related to transistors:
1. Threshold voltage is the minimum gate voltage needed to create a conducting path between source and drain, and depends on oxide thickness, temperature, and random dopant fluctuations.
2. Latchup refers to a short circuit formed between power and ground rails in an integrated circuit, caused by interaction between parasitic bipolar transistors.
3. Electromigration is the forced movement of metal ions due to an electric field, with atoms traveling toward the positive conductor end and vacancies toward the negative end.
4. Mobility degradation occurs due to lateral and vertical electric fields scattering carriers, reducing surface mobility as channel lengths shrink.
The study examines the effect of inflation, investment, life expectancy and literacy rate on per capita GDP across 20 countries using ordinary least squares regression. Initially, the regression results show inflation, investment and literacy rate have a negative effect, while life expectancy has a positive effect on per capita GDP. Sri Lanka, USA and Japan are identified as potential outliers based on their high residuals. Running the regression after removing these outliers improves the model fit and explanatory power of the variables. Diagnostic tests find no evidence of misspecification or heteroskedasticity, validating the OLS estimates.

2) It proposes using a Knowles adder in the middle stage and an optimized ripple carry adder instead of a Brent-Kung adder and normal RCA to improve speed and reduce area.

DEFINITION of 'Operating Leverage'
A measurement of the degree to which a firm or project incurs a combination of fixed and variable costs.
1. A business that makes few sales, with each sale providing a very high gross margin, is said to be highly leveraged. A business that makes many sales, with each sale contributing a very slight margin, is said to be less leveraged. As the volume of sales in a business increases, each new sale contributes less to fixed costs and more to profitability.
2. A business that has a higher proportion of fixed costs and a lower proportion of variable costs is said to have used more operating leverage. Those businesses with lower fixed costs and higher variable costs are said to employ less operating leverage.
Financial Leverage:
Financial leverage is the degree to which a company uses fixed-income securities such as debt and preferred equity. The more debt financing a company uses, the higher its financial leverage. A high degree of financial leverage means high interest payments, which negatively affect the company's bottom-line earnings per share.
Financial risk is the risk to the stockholders that is caused by an increase in debt and preferred equities in a company's capital structure. As a company increases debt and preferred equities, interest payments increase, reducing EPS. As a result, risk to stockholder return is increased. A company should keep its optimal capital structure in mind when making financing decisions to ensure any increases in debt and preferred equity increase the value of the company.
Ordinary least-squares (OLS) regression is a statistical method used to model relationships between variables. It allows for prediction of a continuous dependent variable from one or more independent variables. The OLS model finds the line of "best fit" by minimizing the sum of the squares of the distances between the observed dependent variable values and the dependent variable values predicted by the linear approximation. Key outputs include coefficients that measure the strength of the relationships, goodness of fit statistics like the residual sum of squares, and tests of significance.

This document discusses optoelectronic devices and provides examples. It introduces optoelectronics as the study of electronic devices that interact with light. Major optoelectronic devices directly convert between electrons and photons, including light-emitting diodes (LEDs), laser diodes, and photodiodes. LEDs emit light when electrically biased and the color depends on the semiconductor material. Laser diodes use stimulated emission to produce coherent light. Photodiodes are photodetectors that generate a current when struck by photons. The document also discusses solar cells and trends in optoelectronic devices.
This document discusses the fundamentals of laser diodes, including:
1) Laser diodes use direct bandgap semiconductors where electron-hole recombination emits photons of light equal to the bandgap energy. Population inversion, needed for lasing, can be achieved through heavy doping of both p-type and n-type materials near the depletion layer.
2) Early laser diodes used homojunctions but now use double heterojunctions of GaAs for the active region surrounded by higher bandgap AlGaAs for better optical confinement.
3) Double heterojunction lasers have lower lasing thresholds than earlier designs due to reduced optical losses from improved carrier and light confinement, though
This document discusses different average-based forecasting methods including simple average, moving average, weighted average, and cumulative average. It provides examples and formulas for calculating forecasts for each method. The simple average method calculates the forecast as the average of all past data points. The moving average method uses the average of the most recent data points. The weighted average assigns different weights to each data point. The cumulative average adds the most recent actual value to the cumulative sum of weighted past increases.
Introduction to differential signal -For RF and EMC engineercriterion123
The document discusses design considerations for differential signaling on PCBs. It notes that differential signaling has advantages of producing less electromagnetic interference and being highly immune to interference. However, it also notes that differences in length or spacing between differential pair traces can reduce these advantages. Specifically, the key points are that the length of each trace in a differential pair should be equal, the spacing between traces should be constant, and bends should be gradual rather than sharp to avoid impedance discontinuities and mode conversion that degrade signal quality and increase noise.
DESIGN OF A CMOS BANDGAP REFERENCE WITH LOWTEMPERATURE COEFFICIENT AND HIGH P...VLSICS Design
A high precision temperature compensated CMOS bandgap reference is presented. The proposed circuit employs current-mode architecture that improves the temperature stability of the output reference voltage as well as the power supply rejection when compared to the conventional voltage-mode bandgap referenc. Using only first order compensation the new architecture can generate an output reference voltage of 550mV with a peak-to-peak variation of 400µV over a wide temperature range from -25oC to +100oC which corresponds to a temperature coefficient of 5.8ppm/oC. The output reference voltage exhibits a variation of 2.4mV for supply voltage ranging from 1.6V to 2.0V at typical process corner. A differential cascaded three-stage operational amplifier is included in the bandgap circuit to improve the power supply rejection of the BGR. Simulation result shows that the power supply rejection ratio of the proposed circuit is 79dB from DC up to 1kHz of frequency. The proposed bandgap reference is implemented using UMC 0.18µm CMOS process and it occupies an active layout area of 0.14mm2.
1. Optical fibers transmit data using pulses of light and are able to carry much higher bandwidths than metal wires.
2. Fibers use total internal reflection to guide light along their length with less loss than wires and are immune to electromagnetic interference.
3. Fibers have various applications including long distance communications, local networks, imaging bundles, and sensors.

An analyst has timed a metal-cutting operation for 50 cycles. The average time per cycle was 10.9 minutes, and the standard deviation was 1.20 minutes for a worker with a performance rating of 139 percen.
This chapter discusses time series analysis and forecasting. The key components are:
1. A time series contains data recorded over time and can be analyzed to identify trends and patterns that may continue in the future.
2. The components of a time series are secular trends, cyclical variation, seasonal variation, and irregular variation.
3. Moving averages and weighted moving averages can be used to smooth time series data and identify trends. Linear and nonlinear trend lines can also model trends in the data.
4. Seasonal indices identify seasonal patterns that repeat each year and can be used to deseasonalize time series data. Autocorrelation tests whether residuals are independent or correlated over time.
This document discusses electrostatic discharge (ESD) protection in integrated circuits. It introduces ESD, outlines common ESD models like the human body model and machine model, and describes key ESD protection mechanisms such as avalanche breakdown and thermal breakdown in nMOS transistors. These protection mechanisms allow ESD protection devices to safely discharge static electricity through controlled conduction paths before thermal damage occurs.
Semiconductor device fabrication is the process used to create the integrated circuits that are present in everyday electrical and electronic devices. It is a multiple-step sequence of photo lithographic and chemical processing steps during which electronic circuits are gradually created on a wafer made of pure semiconducting material. Silicon is almost always used, but various compound semiconductors are used for specialized applications.
The document discusses the topic of autocorrelation. It begins by defining autocorrelation as data that is correlated with itself over successive time periods, rather than being correlated with other external data. It then explains the concept of autocorrelation and how it violates the classical linear regression assumption that disturbances are independent over time. Several potential sources of autocorrelation are described, including omitted variables, interpolation of data, and misspecification of the random error term. The document concludes by providing mathematical expressions that describe how the mean, variance, and covariance of autocorrelated disturbances differ from the independent case.
These slides use concepts from my (Jeff Funk) course entitled Biz Models for Hi-Tech Products to analyze the business model for Transparent and Flexible Displays. Transparent displays provide new forms of value to users particularly in the form of better augmented reality. They also make bi-direction games and other forms of communication and entertainment possible. They can be used in tablet computers, mobile phones, and other electronic devices by tech junkies and other potential users. These slides also explain other aspects of the business model such as the method of value capture, scope of activities, and method of strategic control.
The document discusses 3M's cold shrink joint and termination products for medium voltage cables. It provides details on their key features such as requiring no heat, flames, or special tools during installation. The products use a silicone material and unique delivery system for reliable underground connections. A wide range of kits are available for voltages up to 36kV and cable sizes from 25mm2 to 1000mm2.
IR Drop Analysis and Its Reduction Techniques in Deep Submicron TechnologyIJERA Editor
This paper presents a detailed conceptual analysis of IR Drop effect in deep submicron technologies and its reduction techniques. The IR Drop effect in power/ground network increases rapidly with technology scaling. This affects the timing of the design and hence the desired speed. It is shown that in present day designs, using well known reduction techniques such as wire sizing and decoupling capacitor insertion, may not be sufficient to limit the voltage fluctuations and hence, two more important methods such as selective glitch reduction technique and IR Drop reduction through combinational circuit partitioning are discussed and the issues related to all the techniques are revised.

It provides examples and formulas for calculating forecasts for each method. The simple average method calculates the forecast as the average of all past data points. The moving average method uses the average of the most recent data points. The weighted average assigns different weights to each data point. The cumulative average adds the most recent actual value to the cumulative sum of weighted past increases.

It then explains the concept of autocorrelation and how it violates the classical linear regression assumption that disturbances are independent over time. Several potential sources of autocorrelation are described, including omitted variables, interpolation of data, and misspecification of the random error term. The document concludes by providing mathematical expressions that describe how the mean, variance, and covariance of autocorrelated disturbances differ from the independent case.
These slides use concepts from my (Jeff Funk) course entitled Biz Models for Hi-Tech Products to analyze the business model for Transparent and Flexible Displays. Transparent displays provide new forms of value to users particularly in the form of better augmented reality. They also make bi-direction games and other forms of communication and entertainment possible. They can be used in tablet computers, mobile phones, and other electronic devices by tech junkies and other potential users. These slides also explain other aspects of the business model such as the method of value capture, scope of activities, and method of strategic control.
The document discusses 3M's cold shrink joint and termination products for medium voltage cables. It provides details on their key features such as requiring no heat, flames, or special tools during installation. The products use a silicone material and unique delivery system for reliable underground connections. A wide range of kits are available for voltages up to 36kV and cable sizes from 25mm2 to 1000mm2.
IR Drop Analysis and Its Reduction Techniques in Deep Submicron TechnologyIJERA Editor
This paper presents a detailed conceptual analysis of IR Drop effect in deep submicron technologies and its reduction techniques. The IR Drop effect in power/ground network increases rapidly with technology scaling. This affects the timing of the design and hence the desired speed. It is shown that in present day designs, using well known reduction techniques such as wire sizing and decoupling capacitor insertion, may not be sufficient to limit the voltage fluctuations and hence, two more important methods such as selective glitch reduction technique and IR Drop reduction through combinational circuit partitioning are discussed and the issues related to all the techniques are revised.
Bad Beta, Good Beta

Presentation by Michael-Paul James
Cash flow and discount rate betas estimates stock market risk factors
more efficiently than CAPM over time.
○ Cash flow news
■ Stock returns covariance with cash flows news
○ Discount rate news
■ Stock returns covariance with discount rate news
● “Bad” cash flow beta (risk) demands higher premiums than “good”
discount rate beta (risk).
● Value and small stocks have higher cash flow betas than growth and
large stocks on average.
● High average returns on value and small stocks are appropriate
compensation for risk, not an unrealized benefit to ownership.
● Overweighting small and value stocks benefit low risk aversion equity
investors
● Underweighting small and value stocks benefit high risk aversion
equity investors
● Model offers strong explanatory power in the cross section of asset
returns with theoretical values
● ICAPM outperforms the CAPM in empirical research
QE and money market rates in the Euro areaBenoit Nguyen
Slides presented at the ECB in November. In this paper, we study the impact of the Eurosystem asset purchases on the repo rates. Full paper: https://publications.banque-france.fr/en/eurosystems-asset-purchases-and-money-market-rates
The document describes an estimated dynamic stochastic general equilibrium (DSGE) model of the Indian economy that incorporates important features like financial frictions and both formal and informal sectors. It estimates three nested models of increasing complexity and finds strongest support for the two-sector model with financial and labor market frictions. This model provides estimates of the size of India's informal sector from Bayesian maximum likelihood estimation and better matches key macroeconomic moments compared to simpler models.
7_Analysing and Interpreting the Yield Curve.pptMurat Öztürkmen
The document discusses analysing and interpreting the yield curve. It covers the importance of the yield curve, constructing the curve from discount functions, theories like the expectations hypothesis and liquidity preference theory, the formal relationship between spot and forward rates, interpreting the shape of the curve, and fitting the curve from market data. Specifically, it notes the challenges of fitting the curve given a lack of liquid market data inputs and impact of bid-offer spreads, and recommends using a non-parametric interpolation method like the Svensson model to produce a smoother forward curve.

● Many variables are correlated with subsequent stock returns
● In the previous research, historical average stock returns have
outperformed most contenders
● Predictor variables in this paper outperformed out-of-sample once
restrictions were imposed on coefficient signs and return forecast
○ Small explanatory power, meaningful economic significance
● Although not fully described asset prices, out-of-sample performance
improves.
● Models generate meaningful utility gains for mean-variance investors
● Data accessibility and improvement may prove more valuable than
theoretical restrictions
Credit Risk and Monetary Pass-through. Evidence from ChileEesti Pank
The document discusses a study analyzing the relationship between monetary policy rates, credit risk measures, and commercial interest rates on business loans in Chile. It presents preliminary analysis showing no clear evidence of cointegrating relationships between the variables. The study then shifts to a univariate model allowing for asymmetric pass-through of policy rate changes and the role of monetary policy expectations. It notes some issues with autocorrelated residuals that are addressed by including MA terms in the residuals. The goal is to better quantify how credit risk changes impact the pass-through of policy rates to commercial lending rates.
Trading Strategies Based on Market Impact of Macroeconomic Announcementsby A...Quantopian
1) The document discusses trading strategies based on the market impact of macroeconomic announcements. It analyzes 18 major US macroeconomic indicators from 2009-2013 and their impact on equity ETF returns on announcement days.
2) Key findings include several indicators having statistically significant impact on returns, including ISM Manufacturing Index, Non-Farm Payrolls, International Trade Balance, and Housing Starts. Trading strategies based on announcements of significant indicators achieved higher risk-adjusted returns than buy-and-hold.
3) The study also analyzes the impact of economic announcement surprises, actual changes, and expected changes. It found that strategies based on actual changes generally had the lowest volatility and performed well even before and after the
1) The use of structured credit products grew dramatically from 1996 to 2008, especially credit default swaps and collateralized debt obligations (CDOs).
2) The Gaussian copula model was widely used to price CDOs, but it had limitations and flaws that became apparent, such as assuming a single correlation parameter and not allowing for idiosyncratic defaults.
3) More advanced models were developed to address these issues, including stochastic correlation models, implied copula approaches, and dynamic loss models. However, fitting market prices remained challenging.
The document discusses cash flow estimation and risk analysis for a proposed capital project. It provides details of the project costs, revenues, expenses, tax rates, and other assumptions to estimate annual and terminal cash flows. Sensitivity analysis is performed considering changes to the sales forecast. Scenario analysis is conducted based on possible sales cases, and expected NPV, standard deviation of NPV, and coefficient of variation of NPV are calculated. The project is determined to be a high-risk project compared to the firm's average risk profile.

This document summarizes a presentation about assessing CECL models. It discusses that CECL requires estimating lifetime expected credit losses using multiple components and economic scenarios, which makes the models complex and outcomes difficult to assess. It emphasizes that back-testing, sensitivity analysis, and scenario analysis are important to evaluate whether the models perform reasonably under different economic conditions and assess the impact of assumptions. It also stresses the need to review outcomes and test assumptions at granular levels by risk drivers and perform qualitative adjustments through model risk management.
"The Seniority Structure of Sovereign Debt" by Christoph Trebesch, Matthias S...ADEMU_Project
1) The document analyzes the seniority structure of sovereign debt using data on debt arrears and debt restructuring haircuts from 1980-2006.
2) It finds that official creditors like the IMF and World Bank tend to be more senior than other creditors like bilateral or commercial banks based on lower levels of arrears and haircuts.
3) However, bondholders appear to have equal or higher seniority than official creditors based on analyses of arrears and haircut data during debt crises.

The exchange rate at the time of remittance is critical to Maple Energy as it directly impacts their returns, hedging costs, profitability, competitiveness, and financial planning. Fluctuations in exchange rate can significantly alter Maple Energy's expected earnings and cash flows.
B. Regulatory restrictions on investment returns
Regulatory restrictions on investment returns are critical to Maple Energy as they limit potential profits and introduce uncertainty. This hinders financial planning and decision making. It also increases risk exposure.
C. Tax benefits
Tax benefits are important for Maple Energy as they boost post-tax returns and cash flows. This enhances the overall profitability and attractiveness of the investment. Loss of tax benefits can negatively impact the project viability

Firm level shocks propagate in production networks
● Customers drop 2-3% in sales growth when suppliers suffer a disaster
○ 25% drop in sales growth with respect to sample average of 10%
○ Temporary effect, without prior trends
○ Losses only affect active customer-supplier relationships
○ Larger effect when supplier produces differentiated goods with
high R&D, more patents, thus difficult to replace
○ Customer suffers 1% drop in market equity value
● Other suppliers experience drop in sales growth after another supplier
is hit, when customers are shared.
● Input disruptions are not compensated, resulting in sector wide losses
● Input specificity is a key determinant of the propagation of

The document summarizes a research paper that examines hypotheses for property-liability insurer reserve errors. It analyzes two measurements of reserve error and tests four main hypotheses from the literature - taxes, income smoothing, rate regulation incentives, and financial weakness. The results found that the choice of reserve error measurement impacted the findings. There was little evidence for income smoothing. Evidence supported overreserving for tax purposes under one measurement but not the other. Rate regulation incentives were supported. Financial weakness was linked to underreserving rather than deception.

A toxic combination of 15 years of low growth, and four decades of high inequality, has left Britain poorer and falling behind its peers. Productivity growth is weak and public investment is low, while wages today are no higher than they were before the financial crisis. Britain needs a new economic strategy to lift itself out of stagnation.
Scotland is in many ways a microcosm of this challenge. It has become a hub for creative industries, is home to several world-class universities and a thriving community of businesses – strengths that need to be harness and leveraged. But it also has high levels of deprivation, with homelessness reaching a record high and nearly half a million people living in very deep poverty last year. Scotland won’t be truly thriving unless it finds ways to ensure that all its inhabitants benefit from growth and investment. This is the central challenge facing policy makers both in Holyrood and Westminster.
What should a new national economic strategy for Scotland include? What would the pursuit of stronger economic growth mean for local, national and UK-wide policy makers? How will economic change affect the jobs we do, the places we live and the businesses we work for? And what are the prospects for cities like Glasgow, and nations like Scotland, in rising to these challenges?

4. History of News Decomposition
4
● Return beta decomposed into discount rate and cash flow news to
measure time-series and cross sectional variations (Campbell and
Shiller, 1988)
○ Cash flow (CF) news captures firm fundamentals
○ Discount rate (DR) news captures risk aversion and sentiment
● Return decomposition approach
○ For simplicity, researchers directly modeled discount rate news
then labeled the residual as cash flow news.
○ Issues
■ Captures misspecification error of discount rate news, which is
inherently difficult to measure.
■ Omitted DR variables are passed to CF, distorting relationship
Michael-Paul James
5. Seeking Misspecification Confirmation
5
● Return decomposition approach on Treasury bond returns
○ Variation should be driven solely by discount rate news
■ Fixed cash flows (βCF
= 0): no nominal cash flow uncertainty
■ Real interest rate and inflation shocks solely effect returns
■ Any cash flow news would be the aggregation of modeling
noise
○ Estimated variance of CF news is greater than or equal to DR news
■ Longer maturity bonds had even higher βCF
■ Likely caused by missing state variables in DR news
Michael-Paul James
6. Equities and Noise
6
● Playing with the variables
○ Benchmark case:
■ 10-year smoothed price-earnings (PE) ratio
■ Term spread (long-term less short-term bond yields)
■ Value spread (log book-to-market small value less small
growth stocks)
○ Persistence drives impact of state variables, leading to estimation
reversals with close substitutes and differing sample periods
○ Substitutes for 10-year smoothed price-earnings (PE) ratio
■ 1-year PE ratio ■ Dividend yield
■ Book-to-market ratio ■ Book-to-market spread
Michael-Paul James
7. Substitutes and Reversals
7
● Benchmark case concludes DR variance is greater than CF variance
○ Driven by high persistence of state variables
● Substitutes effects
○ Improved explanatory power (>R2
) and greater significance of
other variables
○ Lower value stock βCF
, generally smaller than βDR
● Substitutes for 10-year smoothed price-earnings (PE) ratio
○ 1-year PE ratio: CF variance is greater than or equal to DR
○ Book-to-market ratio: CF variance is greater than or equal to DR
○ Dividend yield: CF variance slightly higher than DR
○ Book-to-market spread: CF variance is greater than DR
Michael-Paul James
8. Not Robustness, Specification
8
● Model misspecification leads to opposite conclusions: not a robustness
issue but a crucial one
● Predictive variables relate to the macroeconomy therefore all are well
motivated, but not necessarily correct.
● Analysis must directly measure or model CF and DR news individually
to allow for a third residual term (error) to maintain a balanced
relationship between variables
● Model uncertainty can be leveraged with the Bayesian model
averaging approach to a large set of predictive variables
Michael-Paul James
13. Decomposition Procedure
13
● CF news as difference between total unexpected return and DR news
● Adjustments
○ Excess returns in VAR and beta calculation
○ Lag of market news (mitigates stale-price problem)
Michael-Paul James
14. ICAPM Interpretation
14
● Approximate discrete-time version of Merton’s intertemporal CAPM
● ri,t+1
return for asset i ● rf,t+1
risk-free rate
● σ2
M
market portfolio variance ● γ risk-aversion coefficient (>1)
● Integrate VAR system: state variables combined into either CF or DR
Michael-Paul James
15. Implications
15
● VAR system (assumed)
● cov(ei,t
,u2,t
)=0, xt
is predictable only by its lag variables. u1,t+1
& u2,t+1
are
innovations in the return and x
Michael-Paul James
16. Omitting the Second State Variable x
16
● Omitted variable ● shock → yt
= u1,t
+ α2
xt-1
● Both betas change in opposite directions when α1
> 0
● Simultaneous impact on both betas exaggerate/inverse relationship
Michael-Paul James
17. Conclusion
17
● “The essence of the residual based return decomposition approach is
to compare the modeled part with the residual; conclusions are
usually a choice between more important and less important or
between higher and lower.”
● “Since model misspecification can lead to opposite conclusion this
sensitivity is not a robustness issue; it is a vital issue.”
Michael-Paul James
19. Setting up the Treasury Regression

● Log linear approximation

We apply the return decomposition approach to Treasury bond returns using annual data (aggregated from monthly data) covering 1953–2002.
In Panel A, we decompose the excess return of intermediate-term Treasury bond into discount rate (DR) news and cash flow (CF) news. We
then report the variances of the two components and their covariance. The state variables include different combinations of the term spread
(the difference between the long-term and short-term bond yields), real interest rate, inflation, and credit spread (Baa over Aaa bond yield). The
plus signs indicate the selected variables in each scenario. In Panel B, we use the intermediate-term Treasury bond (from Panel A) as our bond
market portfolio and calculate the discount rate beta and cash flow beta for 30-day T-bill and long-term bond. Similarly, in Panel C1, we
calculate the betas for Fama-Bliss zero-coupon bonds ranging from two to five years. In Panel C2, we calculate the betas for the Fama bond
portfolios ranging from one year to 10 years. In Panels B and C, the “Diff” columns report the differences in betas of two adjacent portfolios with
different maturities; the “βCF − βDR” columns report the differences in cash flow and discount rate betas of the same portfolio. In Panels B and
C, we report bootstrap standard errors (S.E.) from 10,000 simulated realizations.

We directly model both the DR news and CF news using two separate VAR systems. To avoid cash flow seasonality, all variables are converted into annual frequency. The VAR to predict the
discount rate includes the same variables as in the benchmark case.We use two cash flow proxies: dividend growth rate and earnings return on book equity (ROE). The VAR to predict
dividend growth rate includes dividend growth rate, market equity return, and dividend yield; the VAR to predict ROE includes ROE, market equity return, and book-to-market. For both
cash flow measures, we further decompose the cash flow news into two components. The first is the residual of the cash flow prediction from the cash flow VAR, which we call the current
component. The second is the rest of the cash flow news that considers the impact of the current innovations of state variables on expected future cash flow growth. Because we directly
model both cash flow and discount rate news, they will not add up exactly to the return news, leaving a noise component. For all four news components– the current and future cash flow
news, the discount rate news, and the news noise—we present the cross-sectional betas. In addition, we present the cash flow beta (i.e., the sum of the current and future cash flow betas)
plus the noise beta, which is equivalent to the cash flow beta if we model only the discount rate news but back out the cash flow news as the residual. Similarly, we also present the
discount rate beta plus the noise beta, which is equivalent to the discount rate beta if we model only the cash flow news but back out the discount rate news as the residual. Panel A
reports the case for dividend growth rate; Panel B reports the case for ROE.

We apply the Bayesian model averaging method, following Avramov (2002) and Cremers (2002), to a large set of predictive variables. In particular, we assign equal prior probability to each
combination of state variables, but update the posterior probability according to the predictability of market excess returns. We then report the expected cash flow betas of 25 size and
book-to-market portfolios using the posterior probability. The first three panels vary only because we replace the 10-year PE ratio by either the 1-year PE ratio or the dividend yield. In Panel
D, we replace the value spread by the book-to-market spread and the market-to-book spread, following Liu and Zhang (2008).

We study the cross-sectional pattern of cash flow betas when alternative specifications are used. In Panel A, we use the macro variables by Petkova (2004) that provide intuitive
interpretations on the Fama-French factors. In Panel B, we add variables shown by Lettau and Ludvigson (2001a, 2001b) and Ludvigson and Ng (2005) to exhibit good predictive power for
equity returns. Panel B uses quarterly data because these variables are available only at quarterly frequency. The standard errors of the differences in the cash flow betas between large
and small, as well as value and growth firms, are obtained through bootstrapping 10,000 realizations. We present results only for the 1963–2001 period.

36. Summary
36
● Cross sectional pattern of CF betas in Campbell and Vuolteenaho
seems to be a special case: value stocks do not have higher betas than
growth stocks for most specifications
○ Direct model of CF news
○ Bayesian model averaging approach
○ Principle component analysis
○ Special specifications motivated by economic reasoning
● Relative importance of CF and DR variances flips without clear pattern
● It is easy to draw opposite conclusions even with motivated variables
● Decompose directly modeled DR news, CF news, & residual news
● Mitigate model uncertainty with Bayesian model averaging approach
Michael-Paul James
38. Industry portfolios
38
● If cash flow beta is important to cost of equity, it is price in portfolios
● Tested against the Fama-French 48 industry portfolios
○ Lower CF betas tend to have higher returns
○ CF beta is significantly negative (wrong sign)
○ Higher CF betas should earn lower expected returns and have
lower costs of capital: opposite of CF beta risk interpretation.
Michael-Paul James
39. Post-1952 data and other checks
39
● Post 1952 data
○ Shift in variance after 1952, while CAPM breaks down in 1962
○ Clear decreasing cash flow beta trend from growth to value
■ Reversed from pre 1952 even with benchmark case
■ Trend is stable with other state variables
● Other checks that do not change core results
○ Magnitude of ρ ○ Data frequency
○ Additional VAR lags including 36 month rolling windows
○ Conditional betas
○ Use changes to state variables rather than levels
■ CF news acts like return itself, DR is small. Value lower βCF
Michael-Paul James
41. Oops, Research Made a Boo Boo
41
● Directly modeling discount rate news and backing out cash flow news
adds residual news to the latter
○ The method has led to erroneous conclusions:
■ Larger relative DR variance
■ Value stocks earn higher returns due to higher βCF
■ βCF
is more important than total βtotal
○ DR news cannot be accurately estimated (low predictive power)
and backed out CF news inherits large misspecification error of DR
○ Modeled Treasury bonds reveals higher CF variance with no real CF
risk
○ Minor changes in predictive variables produce opposite results
Michael-Paul James
42. The Residual Effect
42
● Directly modeling cash flow news, discount rate news, and residual
○ Value firms have both lower modeled CF betas and DR betas, but
higher residual betas, indicating that the results in the current
literature are driven by the residual news.
Michael-Paul James
43. Motivating Discourse
43
● 373 citations on google scholar
● Undermines fundamental assumptions leading to new lines of inquiry
● Extensions
○ Ultimately what is residual news? Can it be measured? What are
its sources?
○ How does one motivate variables to accurately measure CF and DR
news betas?
○ How does investor sentiment interplay with cash flow
information?
