Our paper aims to empirically test the significance of the credit spreads and excess returns of the market portfolio in predicting the U.S. business cycles. We adopt the probit model to estimate the partial effects of the variables using data from the Federal Reserve Economic Data – St. Louis Fed (FRED) and the National Bureau of Economic Research (NBER) from 1993:12 to 2014:08. Results show that the contemporaneous regression model is not significant while the predictive regression model is significant. Our tests show that only the credit spread variable lagged by one period is significant and that the lagged variables of the excess returns of the market portfolio is also significant. Therefore, we can conclude that credit spreads and excess returns of the market portfolio can predict U.S. business cycles to a certain extent.
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.

Determinants of the implied equity risk premium in BrazilFGV Brazil
This paper proposes and tests market determinants of the equity risk premium (ERP) in Brazil. We use implied ERP, based on the Elton (1999) critique. The ultimate goal of this exercise is to demonstrate that the calculation of implied, as opposed to historical ERP makes sense, because it varies, in the expected direction, with changes in fundamental market indicators. The ERP for Brazil is calculated as a mean of large samples of individual stock prices in each month in the January, 1995 to September, 2015 period, using the “implied risk premium” approach. As determinants of changes in the ERP we obtain, as significant, and in the expected direction: changes in the CDI rate, in the country debt risk spread, in the US market liquidity premium and in the level of the S&P500. The influence of the proposed determining factors is tested with the use of time series regression analysis. The possibility of a change in that relationship with the 2008 crisis was also tested, and the results indicate that the global financial crisis had no significant impact on the nature of the relationship between the ERP and its determining factors. For comparison purposes, we also consider the same variables as determinants of the ERP calculated with average historical returns, as is common in professional practice. First, the constructed series does not exhibit any relationship to known market-events. Second, the variables found to be significantly associated with historical ERP do not exhibit any intuitive relationship with compensation for market risk.

Introduction
This report presents my research work carried out at Credit Suisse from May to September 2012. This study has been pursued in collaboration with the Global Arbitrage Strategies team.
Quantitative analysis strategy developers use sophisticated statistical and optimization techniques to discover and construct new algorithms. These algorithms take advantage of the short term deviation from the ”fair” securities’ prices. Pairs trading is one such quantitative strategy - it is a process of identifying securities that generally move together but are currently ”drifting away”.
Pairs trading is a common strategy among many hedge funds and banks. However, there is not a significant amount of academic literature devoted to it due to its proprietary nature. For a review of some of the existing academic models, see [6], [8], [11] .
Our focus for this analysis is the study of two quantitative approaches to the problem of pairs trading, the first one uses the properties of co-integrated financial time series as a basis for trading strategy, in the second one we model the log-relationship between a pair of stock prices as an Ornstein-Uhlenbeck process and use this to formulate a portfolio optimization based stochastic control problem.
This study was performed to show that under certain assumptions the two approaches are equivalent.
Practitioners most often use a fundamentally driven approach, analyzing the performance of stocks around a market event and implement strategies using back-tested trading levels.
We also study an example of a fundamentally driven strategy, using market reaction to a stock being dropped or added to the MSCI World Standard, as a signal for a pair trading strategy on those stocks once their inclusion/exclusion has been made effective.
This report is organized as follows. Section 1 provides some background on pairs trading strategy. The theoretical results are described in Section 2. Section 3
This project looks at the abilities of GARCH family models to forecast stock market volatility. FTSE 100 stock market returns are covered over the 10 years period in attempt to contribute to wide range of studies made on GARCH models.

This paper presents two models of key determinants in the evolution of the shadow banking system. First of all, a shadow banking measure is built from a European perspective. Secondly, information on several variables is retrieved basing their selection in previous literature. Thirdly, those variables are grouped in: 1) the base model: real GDP, Institutional investors’ assets, term-spread, banks’ net interest margin and liquidity; and 2) the extended model: the former five plus an indicator of systemic stress, an index of banking concentration and inflation. Finally, regression analysis on those models is conducted for different countries’ samples. Both OLS and panel data analysis is undergone. Results suggest important and consistent geographical differences in relations between shadow banking and key determinant variables’ effects. Thus, this essay provides financial authorities with a valuable benchmark to which they should pay attention before designing optimal policies seeking to reduce the financial risk that shadow banking entails.

Bankruptcy Prediction is an art of predicting bankruptcy and various measures of financial
distress of public or private firms. In recent past days we are seeing many cases with distress
and bankrupted. It is a huge area of finance and accounting research. The importance of the
world is due partially to the relevance for creditors and investors in evaluating the likelihood
that a firm may go bankrupt. The quantity of research is additionally a function of the supply of
data: for public firms which went bankrupt or not, numerous accounting ratios which
may indicate danger can be calculated, and various other potential explanatory variables also
are available. Consequently, the world is well-suited for testing of increasingly sophisticated,
data-intensive forecasting approaches.
The paper re-assesses the impact of exchange rate regimes on macroeconomic performance. We test for the relationship between de jure and de facto exchange rate classifications on the one hand, and inflation, output growth and output volatility on the other. We find that, once high-inflation outliers are excluded from the sample, only hard exchange rate pegs are associated with lower inflation compared to the floating regime. There is no significant relationship between output growth and exchange rate regimes, confirming results from previous studies. De jure pegged regimes (broadly defined) are correlated with higher output volatility, but this relationship is reversed for the de facto classification. The last result points to a potential endogeneity problem present when the de facto classification is used in testing for the relationship between exchange rate behavior and macroeconomic performance.

In this paper, we try to uncover the economic foundations of financial sector development and its
impacts on accelerating economic growth in the given context of emerging economies. We theorize and
empirically test a causally-motivated relationship among economic growth and related key financial sector
variables pertinent to this problem. We accomplish this by analyzing a 20 year panel-data constructed for 30
countries falling within the categorization of an ‘emerging economy’. We estimate the appropriate statistical
models along with related diagnostic tests. Finally, we comment on the strengths and weaknesses of our
approach and we try to explicate the economic rationale and justification for our formulation and the evidences

Dynamic Stress Test Diffusion Model Considering The Credit Score PerformanceGRATeam
After the crisis of 2008, and the important losses and shortfall in capital that it revealed, regulators conducted massive stress testing exercises in order to test the resilience of financial institutions in times of stress conditions. In this context, and considering the impact of these exercises on the banks’ capital, organization and image, this white paper proposes a methodology that diffuses dynamically the stress on the credit rating scale while considering the performance of the credit score. Consequently, the aim is to more accurately reflect the impact of the stress on the portfolio by taking into account the purity of the score and its ability to precisely rank the individuals of the portfolio.
how can I sell pi coins after successfully completing KYCDOT TECH
Pi coins is not launched yet in any exchange 💱 this means it's not swappable, the current pi displaying on coin market cap is the iou version of pi. And you can learn all about that on my previous post.
RIGHT NOW THE ONLY WAY you can sell pi coins is through verified pi merchants. A pi merchant is someone who buys pi coins and resell them to exchanges and crypto whales. Looking forward to hold massive quantities of pi coins before the mainnet launch.
This is because pi network is not doing any pre-sale or ico offerings, the only way to get my coins is from buying from miners. So a merchant facilitates the transactions between the miners and these exchanges holding pi.
I and my friends has sold more than 6000 pi coins successfully with this method. I will be happy to share the contact of my personal pi merchant. The one i trade with, if you have your own merchant you can trade with them. For those who are new.

Message: @Pi_vendor_247 on telegram if u want to sell PI COINS.
1. Mainnet Launch: As of my last knowledge update in January 2022, Pi was still in the testnet phase. Its success will depend on a successful transition to a mainnet, where actual transactions can take place.
2. User Adoption: Pi's success will be closely tied to user adoption. The more users who join the network and actively participate, the stronger the ecosystem can become.
3. Utility and Use Cases: For a cryptocurrency to thrive, it must offer utility and practical use cases. The Pi team has talked about various applications, including peer-to-peer transactions, smart contracts, and more. The development and implementation of these features will be essential.
4. Regulatory Environment: The regulatory environment for cryptocurrencies is evolving globally. How Pi navigates and complies with regulations in various jurisdictions will significantly impact its future.
5. Technology Development: The Pi network must continue to develop and improve its technology, security, and scalability to compete with established cryptocurrencies.
6. Community Engagement: The Pi community plays a critical role in its future. Engaged users can help build trust and grow the network.
7. Monetization and Sustainability: The Pi team's monetization strategy, such as fees, partnerships, or other revenue sources, will affect its long-term sustainability.
It's essential to approach Pi or any new cryptocurrency with caution and conduct due diligence. Cryptocurrency investments involve risks, and potential rewards can be uncertain. The success and future of Pi will depend on the collective efforts of its team, community, and the broader cryptocurrency market dynamics. It's advisable to stay updated on Pi's development and follow any updates from the official Pi Network website or announcements from the team.

Abstract
Our paper aims to empirically test the significance of the credit spreads and excess returns of
the market portfolio in predicting the U.S. business cycles. We adopt the probit model to
estimate the partial effects of the variables using data from the Federal Reserve Economic
Data – St. Louis Fed (FRED) and the National Bureau of Economic Research (NBER) from
1993:12 to 2014:08. Results show that the contemporaneous regression model is not
significant while the predictive regression model is significant. Our tests show that only the
credit spread variable lagged by one period is significant and that the lagged variables of the
excess returns of the market portfolio is also significant. Therefore, we can conclude that credit
spreads and excess returns of the market portfolio can predict U.S. business cycles to a
certain extent.
Key words: Recessions, credit spreads, excess returns of the market portfolio (market
premium), probit models, U.S. business cycles
Introduction
After the most recent and influential business cycles fluctuations and financial crisis (especially
the one of 2008, widely known as ‘Sub Prime Mortgage Crisis’), many researchers put effort
to analyse and understand those variables that can explain recessions. There has been a rich
discussion on the impact of macroeconomic variables that determines the business cycle
fluctuations in the U.S. This research paper has been built upon a broad range of past literature
based on the usage of macroeconomic and financial variables to evaluate and estimate the
probability of recessions.
Estrella and Hardouvelis (1991) and Estrella and Mishkin (1998) have argued that the slope
of the term structure of Treasury yields has strong predictive power for forecasting U.S. cycles.
We use in our research the papers of Estrella and Hardouvelis (1991), being the first to advert
the Treasury term spread as a predictor of recessions. Per their findings, the treasury term
spread has greater explanatory power than a selected benchmark index. Following the
findings of Estrella and Hardouvelis (1991), using a similar research framework, Estrella and
Mishkin (1998) concluded the yield curve spread and the stock price index being the most
useful financial indicators to forecast recessions. Furthermore, by using the probit model,
Dueker (1997) found that the term spread represents the best recession indicator and
exhibited that the results are robust with lagged dependent variables. Chauvet and Potter
(2005) paper reveals that, otherwise it is difficult to predict recession, they managed to
4. IB9X60 Quantitative Methods for Finance Group 10
construct the probabilities of recession of 2001 by using the probit model that includes the
term structure as a regressor. The outcome of their research is that under the presence of
structural break in a time series could considerably affect recession predictions.
Similarly, we find similar analysis conducted in the European regions, such as France and
Germany, to predict their recession: for instance, both Bismans and Majetti (2012) in France
and Nyberg (2010) in Germany used equivalent approach and adopting the probit model.
Consistent with most the previous past literature, we decided to employ binary response
variables to predict the business cycle fluctuation across time. On the other hand, empirical
studies have been conducted to thoroughly analyse the relationship between credit spread
and economic downturns. For instance, Gilchrist and Zakrajsek (2012) and Faust et al. (2013)
discovered the significance predictive abilities of credit spread on recessions, related to
business cycles.
We ask two primary questions in our research. First, we want to investigate any relationship
between the credit spreads and excess returns of the market portfolio on the probability of a
recessions and whether it is contemporaneous or predictive in nature. Secondly, we want to
determine the sign of lagged variables to ensure that the variables followed economic theory.
Our paper assesses the significance of credit spreads and the excess returns on the market
portfolio (market premium) on predicting business cycle fluctuations in the U.S. from 1993:12
to 2014:08 which merely includes two recessions.
In accordance with many of the prior researches, we extract the U.S recession data from the
Federal Reserve Economic Data – St. Louis Fed (FRED) and the National Bureau of Economic
Research (NBER) for our analysis. This variable is binary; a value of 1 represents a
recessionary period, while a value of 0 represents an expansionary period. In our set of data,
the recession begins from the first day of the period following a peak and ends on the day of
the period of the trough. On the contrary, our leading financial indicators have continuous
distributions.
Given the characteristics of our data, we adopt the probit model following previous literature
to estimate the explanatory variables. We proceed determining the credit spread as the
difference between the Baa Moodys and the Aaa Moodys and the excess return of the market
portfolio as the difference between the value weighted market portfolio and the risk-free rate,
as defined by Bianchi, Guidolin and Ravazzolo (2013).
In general, we would expect that there would be a positive relationship between the credit
spread and the likelihood of a recession and a negative relationship between the excess
returns of the market portfolio and the likelihood of a recession.
5. IB9X60 Quantitative Methods for Finance Group 10
Having recognised that the model is a time series, we conduct a unit root testing following the
methodology footsteps of Karunaratne (2002). We begin testing the stationarity of the
independent variables (credit spread and excess returns of the market portfolio) to ensure that
the regression is not spurious (Granger & Newbold, 1973). We run the Dickey-Fuller test for
unit root and the Augmented Dickey-Fuller test for unit root to confirm that these variables are
stationary (see Dickey & Fuller, 1979).
We have examined the contemporaneous regression model where we estimate the effects of
the current credit spreads and the excess returns of the market portfolio on the probability of
a recession in that period. Intuitively, given that the data in the current period is unobservable,
we should not find any significance in the contemporaneous regression model.
Instead, a predictive regression model would be much more appropriate. We proceed by
estimating the effects of the lagged credit spreads and the excess returns of the market
portfolio on the probability of a recession. We start by estimating the probit model on a single
lag of each variable and continue adding further lagged variables until we find an insignificant
lag.
Methodology
In the following chapter, we describe the empirical methods that we use to estimate the
significance of financial indicators in determining U.S. business cycles. First, we will start by
discussing the time series model as well as the need to test the stationarity of variables to
avoid the presence of spurious regressions that may lead to misleading inferences. Next, we
describe the conventions of the probit model and its advantages along with the maximum
likelihood estimator. Lastly, we address the interpretation of results and goodness of fit
measures.
Time series model
The nature of our data (time series), as discussed by Woolridge (2008), is characterised by;
trends and seasonal patterns over time, and the dependency of observations across time.
Stationarity
In our paper, it is essential to understand if the dependent and independent variables are
stationary or not. Given that our dependent variable yt is binary, we do not need to conduct a
stationary test. Thus, we first proceed by testing the stationarity of our variables to prevent the
occurrence of spurious regressions, as discussed by Granger & Newbold (1973), which may
6. IB9X60 Quantitative Methods for Finance Group 10
result in a high R2
even when the series are independent of each other. We use the Augmented
Dickey-Fuller test for unit root (see Dickey & Fuller, 1979) for models with a constant (M1),
with a time trend term included (M2), and a drift term included (M3):
∆𝑦𝑡 = 𝛼 + 𝛿𝑦𝑡−1 + 𝜖 𝑡 (𝑀1)
∆𝑦𝑡 = 𝛼 + 𝛿𝑦𝑡−1 + 𝛽2 𝑡 + 𝜖 𝑡 (𝑀2)
∆𝑦𝑡 = 𝛼 + 𝛿𝑦𝑡−1 + 𝛽2∆𝑦𝑡−1 + 𝜖 𝑡 (𝑀3)
Hypothesis:
H0: 𝛿 = 0 (The process is nonstationary)
H1: 𝛿 ≠ 0 (The process is stationary)
The resulting tau statistic:
𝐷𝐹𝜏 =
𝛿̂
𝑠𝑒(𝛿̂)
is compared to the relevant critical values that were tabulated by David Dickey and Wayne
Fuller (ADF critical values) or a more extensive table by MacKinnon. If the tau statistic was
less than the critical value, we reject the null hypothesis (H0: 𝜹 = 0) and conclude that the
process is stationary.
The probit model
Estrella & Mishkin (1996) and Liu and Moench (2016), argue that the probit model is
appropriate in predicting business cycles because of its simplicity and ease of use.
Given that the dependent variable (recession indicator) is discrete:
𝑅𝑒𝑐𝑒𝑠𝑠𝑖𝑜𝑛 𝑡 = {
1, 𝑖𝑓 𝑖𝑛 𝑟𝑒𝑐𝑒𝑠𝑠𝑖𝑜𝑛
0, 𝑜𝑡ℎ𝑒𝑟𝑤𝑖𝑠𝑒
(1)
We estimate the probit model in the form of:
𝑃(𝑦 = 1|𝑥) = 𝐺 (𝛽0 + ∑(𝛽𝑖 𝑋𝑖)
𝑛
𝑖=1
) = 𝐺(𝑧) (2)
where G is the standard normal cumulative density function (cdf):
𝐺(𝑧) = 𝜑(𝑧) ≡ ∫ 𝜑(𝑣)
𝑧
−∞
𝑑𝑣 (3)
where 𝜑(v) is the standard normal probability density function (pdf).
7. IB9X60 Quantitative Methods for Finance Group 10
The y variable is the binary recession indicator (rec) and the X’s are the credit spread
(credspr), market premium (marketprem) and their lags.
The advantage of the probit model, as discussed by Brooks (2014), is that equation (2) is
strictly between zero and one for all values of the parameters, circumventing the issues of the
linear probability model. Another advantage of the probit model is that it assumes that the error
terms follow the standard normally distribution. This results in error terms being
homoscedastic and not serially correlated.
Maximum Likelihood Estimator
The probit model is estimated using the maximum likelihood estimation (MLE) which – under
general conditions – are consistent, asymptotically normal, and asymptotically efficient (see
Wooldridge, 2008, Chapter 13).
Likelihood function:
𝑓(𝑦𝑖|𝑥𝑖; 𝛽) = [𝐺(𝑥𝑖 𝛽)] 𝑦𝑖[1 − 𝐺(𝑥𝑖 𝛽)]1−𝑦𝑖 (4)
Where, y = 0, 1
Log-likelihood function:
log[𝑓(𝑦𝑖|𝑥𝑖; 𝛽)] = 𝑦𝑖 𝑙𝑜𝑔[𝐺(𝑥𝑖 𝛽)] + (1 − 𝑦1𝑖)𝑙𝑜𝑔[1 − 𝐺(𝑥𝑖 𝛽)] (5)
MLE estimator:
𝛽̂ 𝑀𝐿𝐸 = arg min
𝛽
∑{𝑦𝑖 log[𝐺(𝑥𝑖 𝛽)] + (1 − 𝑦𝑖) log[1 − 𝐺(𝑥𝑖 𝛽)]}

Partial Effect at the Average
partial effect of xj on 𝑝(𝑦 = 1|𝑋) is:
𝜕𝑝(𝑦 = 1|𝑋)
𝜕𝑥𝑗
= 𝛽𝑗 ∙ 𝑔(𝑋𝛽) (7)
Where 𝑔(𝑧) ≡
𝑑𝐺(𝑧)
𝑑𝑧
is the pdf of G(z), the cdf.
Hence, since 𝑔(𝑧) > 0 for all 𝑧 ∈ 𝑅, the sign is determined by 𝛽𝑗
8. IB9X60 Quantitative Methods for Finance Group 10
Relative partial effect
The relative partial effect of 𝑥𝑗 and 𝑥 𝑘 on 𝑝(𝑦 = 1|𝑋) is:
𝛽𝑗 ∙ 𝑔(𝑋𝛽)
𝛽 𝑘 ∙ 𝑔(𝑋𝛽)
=
𝛽𝑗
𝛽 𝑘

Lastly, we measure the goodness of fit using the pseudo-R2
𝑃𝑠𝑒𝑢𝑑𝑜 − 𝑅2

2(𝑙1 − 𝑙0)

(8)
However, the pseudo-R2
has no natural interpretation and it is more informative to do a

Data description
Our paper is based on data from the Federal Reserve Economic Data – St. Louis Fed (FRED)
and the National Bureau of Economic Research (NBER) from period 1993:12 to 2014:08.
We calculate credit spread by subtracting the Baa Moody’s with the Aaa Moody’s and the
excess return on the market portfolio by subtracting the value weighted market portfolio by the
risk-free rate. We measure business cycles fluctuations in the U.S. by using the binary
recession indicator which takes a value of 1 represents a recessionary period, while a value
of 0 represents an expansionary period. Recessions are defined by the National Bureau of
Economic Research (NBER) from the first day of the period following a peak and ends on the
day of the period of the trough.
9. IB9X60 Quantitative Methods for Finance Group 10
An important consideration is that we use the first order difference of the credit spread because
of stationarity considerations. We also consider lagged terms for the market premium, the
logic being that recent historic market premiums may have an explanatory effect in the
probability of a recession.

From the table, we can reject the null hypothesis (H0: 𝜹 = 0) that credit spread is non-stationary
since the augmented dickey-fuller test (M3) is significant at the 5% level and the market
premium is stationary at the 1% significance level. As such, we can now use the variables as
per normal.
Specifying the model
The table 2 presents our empirical findings where we run a preliminary probit model (P1)
regressing the recession indicator (rec) on the credit spread (credspr) and market premium
(marketprem). We find that the coefficient of marketpremt is not significant at the 10% level.
Next, we hypothesise that the lag variables of credit spread and market premiums will have
explanatory power on the model since this data is available to the market at time t (P2). We
find that all coefficients are insignificant at the 5% level.
10. IB9X60 Quantitative Methods for Finance Group 10
We then estimate a new model (P3) just on the lagged variables (credsprt-1, marketpremt-1)
and obtain significant coefficients at the 5% level.
Following that, we estimate the model (P4) on further lagged variables (credsprt-1, credsprt-2,
marketpremt-1, marketpremt-2). We find that the credsprt-2 is not significant at the 10% level.
Hence, we remove the credsprt-2 and re-run the regression (P5) which yields coefficients
significant at the 5% level.
Lastly, we add the marketpremt-3 variable in our final model (P6) and find that all coefficients
are now significant at the 5% level. We decide to stop here to avoid overfitting the model by
including some variables and not others.
From table 2, we can observe that the R2
increases as we add more variables into the model,
which is what we would expect due to the nature of the R2
. However, we note that our final
model (P6) has an increase of 0.03 as compared to that of the previous model (P5). This would
suggest that there is indeed additional explanatory power by adding the variable (
marketpremt-
3) into the model.
12. IB9X60 Quantitative Methods for Finance Group 10
Interpretation of results
Using model P6, we estimate the partial effects of the independent variables:

p-values in parenthesis
Hence, a one unit increase in the lagged credit spread (credsprt-1) results in an increase of
19.38% in the probability of a recession; this is in line with economic theory since recessions
usually follow a period of tight credit (see Eckstein & Sinai, 1986).
In addition, a one unit increase in the lagged market premiums (marketpremt-1), (marketpremt-
2), (marketpremt-3), result in a decrease of -0.0072%, -0.0069%, -0.0069% in the probability of
a recession respectively. This is also in line with economic theory since a decrease in market
premiums may signal the beginning of a recession.
Next, we interpret the relative marginal effect of each variable:
Table 4: Relative marginal effect
credsprt-1 marketpremt-1 marketpremt-2 marketpremt-3
credsprt-1 1 -26.996 -28.142 -27.936
marketpremt-1 -0.037 1 1.042 1.035
marketpremt-2 -0.036 0.959 1 0.993
marketpremt-3 -0.036 0.966 1.007 1
Values are interpreted as the left column over the top row
From table 4, we can see that the credit spread generally has a much higher effect –
approximately 27 to 28 times more – on a recession relative to the market premium. In
contrast, the market premium lags have an equal effect relative to themselves on the
probability of a recession. We conclude from the interpretation of the relative marginal effects,
the credit spread dominates the market premium in explaining the probability of a recession.
13. IB9X60 Quantitative Methods for Finance Group 10
Caveats or limitations
In this paper, we avoid overfitting the model by including some variables while excluding others
(the lagged variables of market premium and credit spread) to maximise the R2
. Thus, we only
used models that have plausible economic justifications.
The salient limitations of our paper are contained in our data set. Firstly, we defined the credit
spread by using the difference between the Baa Moody’s and the Aaa Moody’s. This limits the
credit spread to changes in the investment grade bonds but not the junk bonds, which is greatly
distortive. Secondly, the length of the time taken into consideration is not sufficient because it
only includes two recessions.
The nature of the recession also plays a significant role as to whether the credit spread is a
significant variable or not. In the 2001 recession, which was the result of the dot-com bubble,
credit spreads were not affected since technology companies usually did not issue debt
instruments. Hence, we expect that the credit spread variable would not be significant during
this period. In contrast, given that the 2007-09 recession was largely caused by the credit
crisis, we expect the credit spread variable to be more significant during this period.
Lastly, we recognise that the model is extremely restricted since we only examine two financial
variables. Hence, it is necessary to complement the model by adding in more financial
variables as suggested by Estrella & Mishkin (1998).
Conclusion
In summary, we have examined the predictive effect of the credit spread and market premium
variables on the probability of falling into a recession. Consistently with economic theories,
credit spreads are indeed positively related to the probability of a recession while the market
premium is negatively related to the probability of a recession.
Our findings show that a contemporaneous regression was found to be insignificant. This is in
line with what we would expect as the data for the current period is unobservable, thus we
should only use a predictive regression where we use the lags of the variables. Yet, based on
our results, we find that the credit spread variable lagged by 2 periods is not significant. On
the other hand, lagged variables of market premium are found to be significant even in longer
lags. This suggest that market premium has a longer lasting effect on the probability of a
recession.
