Book excerpt: This dissertation comprises three papers examining questions in asset pricing, investigating the implications of new asset pricing theories on the cross-section and time series of asset prices. The papers are as follows: Chapter 1 studies how the fat-tailed distribution of US firm size generates extra risk premiums compared to the classical theory. The author refers to this fat tail as "granularity" and shows that it breaks the diversification of idiosyncratic risks assumed by arbitrage pricing theory (APT) to imply factor models. In the cross-section, large firms have higher idiosyncratic risk premiums than small firms despite having a lower level of risk. This finding explains the negative relation between idiosyncratic risk and risk premium, known as the "idiosyncratic risk premium puzzle." On aggregate, the level of granularity, measured by the Pareto distribution, explains market expected returns since it determines the under-diversification of idiosyncratic risk. Chapter 2 (joint work with Rossen Valkanov and Yan Xu) investigates the joint dynamics and predictability of asset returns for the equity, treasury, and foreign asset investment sectors, utilizing their respective valuation ratios constructed from their intertemporal budget constraints. We propose a new framework that enforces an aggregate accounting identity of the three sectors using a constrained estimation by the GMM method, which accounts for the cyclical movement of the whole economy. Our key finding shows that the government surplus-to-debt ratio negatively predicts the risk premium in the equity and foreign asset investment sectors. Our results suggest that incorporating data from all three sectors and imposing aggregate budget constraints can help to better identify how the fiscal policy adjustment channel propagates throughout the economy. Chapter 3 presents a model for modeling the correlation dynamics of stock returns using a conditional factor model. In this model, the employment of factors helps to reduce the estimation dimension by presenting the asset returns' covariance matrix as a quadratic function of the conditional covariance with factors. The factor structure allows for a closed-form solution for the inverse and determinant of the covariance matrix, which is convenient for computing the likelihood function and allocating a minimum variance portfolio. The model accurately fits the realized correlation among S&P 500 stocks computed from 5-minute data. It also generates out-of-sample minimum variance portfolios with a higher information ratio.

The first essay studies the pricing in the CDS Index (CDX) tranche market, and whether these instruments have been reasonably priced and integrated within the financial market generally, both before and during the financial crisis. We first design a procedure to value CDO tranches using an intensity-based model which falls into the affine model class. The CDX tranche spreads are efficiently explained by a three-factor version of this model, before and during the crisis period. We then construct tradable CDX tranche portfolios, representing the three default intensity factors. These portfolios capture the same exposure as the S&P 500 index optionmarket, to a market crash. We regress these CDX factors against the underlying index, the volatility factor, and the smirk factor, extracted from the index option returns, and against the Fama-French market, size and book-to-market factors. We finally argue that the CDX spreads are integrated in the financial market, and their issuers have not made excess returns. The second essay explores the specifications of jumps for modeling stock price dynamics and cross-sectional option prices. We exploit a long sample of about 16 years of S&P500 returns and option prices for model estimation. We explicitly impose the time-series consistency when jointly fitting the return and option series. We specify a separate jump intensity process which affords a distinct source of uncertainty and persistence level from the volatility process. Our overall conclusion is that simultaneous jumps in return and volatility are helpful in fitting the return, volatility and jump intensity time series, while time-varying jump intensities improve the cross-section fit of the option prices. In the formulation with time-varying jump intensity, both the mean jump size and standard deviation of jump size premia are strengthened. Our MCMC approach to estimate the models is appropriate, because it has been found to be powerful by other authors, and it is suitable for dealing with jumps. To the best of our knowledge, our study provides the the most comprehensive application of the MCMC technique to option pricing in affine jump-diffusion models.

Available in PDF, EPUB and Kindle. Book excerpt: Abstract: A considerable portion of the asset pricing literature considers the demand schedule for asset prices to be perfectly elastic (flat). As argued, asset prices are determined using information about future payoff distribution, as well as the discount rate; consequently, an asset would be priced independent of its available supply. Furthermore, such a flat demand curve is considered to be a consequence of the Efficient Market Hypothesis. My dissertation evaluates and questions the factuality of these assertions. I approach this problem from both an empirical and a theoretical perspective. The general argument is that asset prices do respond to supply-shocks; and changes in aggregate demand, stemming from preference changes, new international investments, or quantitative easing by the Fed, can result in price changes. Hence, asset prices are determined by both demand and supply factors. In the first essay, "Downward Sloping Asset Demand: Evidence from the Treasury Bills Market," I report on my empirical study which establishes the existence of a downward sloping demand curve (DSDC) in the T-bill market. In the second essay, "Asset Pricing: Inelastic Supply," I examine the theoretical issues concerning a downward sloping demand curve. I begin by clarifying a common confusion in the literature, namely, that many asset pricing models imply a flat demand curve. I show that the prominent asset pricing models, including Capital Asset Pricing Model (CAPM), Arbitrage Pricing Theory (APT) and Consumption Capital Asset Pricing Model (CCAPM), all have an underlying DSDC. I further show that, while these models imply the relevance of supply, they are inconvenient as a vehicle for the estimation and analysis of the DSDC in the data. For those purposes, I develop an asset pricing framework based on the stochastic discount factor framework, specifically designed with a DSDC at its heart. I end the essay with a discussion of the framework's implications and applications. In the third essay I develop on the Factor-Augmented Vector-Autoregression (FAVAR) literature, proposing a bias-corrected method. As implemented in the literature, the Principal Component Analysis stage of FAVAR introduces a classical-error-in-variable problem which leads to bias. I propose an instrument-based method for bias correction.

Book excerpt: This dissertation studies how asset prices are related to various macroeconomic and financial factors. In the first chapter, I examine the influence of external financing costs on growth and asset prices. Using U.S. high-tech firm data and the aggregate financing cost measure of Eisfeldt and Muir (2016), I find that an increase in financing cost can have negative effects on R&D by reducing equity finance. This result suggests that financing cost can have substantial impacts on long-run productivity through the R&D channel. Motivated by this idea, I construct a general equilibrium model where financing costs affect innovation activities and future productivity. My model endogenously generates long-run risk and matches key features of macroeconomic and asset price data. The model produces a sizable equity premium, doing a good job of matching macro moments in the data. Furthermore, a large risk premium of R&D-intensive stocks is justified in the model as in the data. In addition, as a higher financing cost forecasts lower productivity growth in the model, this prediction is supported by empirical evidence. In the second chapter, I investigate whether heterogeneity between domestic and foreign households can help explain the cross-section of stock returns. For this analysis, I apply Yogo’s (2006) durable consumption model to a two-country setting using Korean stock market data. In Korea, U.S. investors have been a dominant foreign investor group, given that the total share of foreigners is considerably large. By incorporating the stochastic discount factor of the U.S. into the model, I find that it plays a significant role in pricing assets. In particular, our model is successful in accounting for the expected excess return of relatively high book-to-market equity groups, producing lower pricing errors than the Fama-French 3 factor model. In the third chapter, I study the effects of debt maturity choice on stock returns and financial structure. I construct a model where firms can issue both short-term and long-term bonds, subject to collateral constraints. I also assume that, when they run financial deficits, firms use equity finance paying issuance costs. The model performs well in matching empirical facts about stock returns and the financial structure of firms. In addition, the model provides an interesting implication that firms substitute between leverage and maturity. In the literature, theoretical explanations for the substitution relationship have been mainly based on conflicts between stakeholders. Without hinging on the contract-theoretic approach, my model replicates the theoretical prediction.

Book excerpt: My dissertation contains three chapters. Chapter one proposes a nonparametric method to evaluate the performance of a conditional factor model in explaining the cross section of stock returns. There are two tests: one is based on the individual pricing error of a conditional model and the other is based on the average pricing error. Empirical results show that for valueweighted portfolios, the conditional CAPM explains none of the asset-pricing anomalies, while the conditional Fama-French three-factor model is able to account for the size effect, and it also helps to explain the value effect and the momentum effect. From a statistical point of view, a conditional model always beats a conditional one because it is closer to the true data-generating process. Chapter two proposes a general equilibrium model to study the implications of prospect theory for individual trading, security prices and trading volume. Its main finding is that different components of prospect theory make different predictions. The concavity/convexity of the value function drives a disposition effect, which in turn leads to momentum in the cross-section of stock returns and a positive correlation between returns and volumes. On the other hand, loss aversion predicts exactly the opposite, namely a reversed disposition effect and reversal in the cross-section of stock returns, as well as a negative correlation between returns and volumes. In a calibrated economy, when prospect theory preference parameters are set at the values estimated by the previous studies, our model can generate price momentum of up to 7% on an annual basis. Chapter three studies the role of aggregate dividend volatility in asset prices. In the model, narrow-framing investors are loss averse over fluctuations in the value of their financial wealth. Persistent dividend volatility indicates persistent fluctuation in their financial wealth and makes stocks undesirable. It helps to explain the salient feature of the stock market including the high mean, excess volatility, and predictability of stock returns while maintaining a low and stable risk-free rate. Consistent with the data, stock returns have a low correlation with consumption growth, and Sharpe ratios are time-varying.

Book excerpt: Essay One: A New Estimate of BetaThis essay examines a new method of estimating systematic risk, or "beta". Due to market imperfection, stock prices, especially those of small firms, do not move with the market index synchronously. Because of nonsynchronous or delayed reaction in price for small firms, the traditional beta estimated from the market model may not be a true reflection of systematic risk. In other words, since stock prices do not fully respond to the market in a single period, the contemporary beta may only reflect the partial systematic risk. As a result, the beta estimated from the market model is underestimated for small firms and overestimated for large firms. The same problem also causes betas estimated from the market model to vary greatly across different estimation horizons. I develop a model of delay/lead price reactions for small/large firms. Based on this model I derive a multiple-period regression equation for the new estimation of beta.^We then estimate the equation for each of the ten size-ranked decile portfolios at different estimation horizons, using monthly, weekly and daily returns. Betas estimated from the optimal estimation horizons for monthly, weekly, and daily returns are discussed. Our results show that, betas estimated at similar horizons, using monthly, weekly, and daily returns, are consistent with each other. Betas estimated for the ten size-decile portfolios from monthly, weekly, and daily average returns are positively related to those returns, respectively. Essay Two: Test of Capital Asset Pricing Model Based on a New Estimate of BetaThis essay tests the Capital Asset Pricing Model (CAPM), based on a new estimate of beta. The test methodology follows the classic Fama-MacBeth (1973) approach, using updated data from 1926-2010.^I ran each test on eleven different periods based on three different estimates of beta: the Ordinary Least Square (OLS) beta, the Scholes-Williams (1977) beta, and a new estimate of beta. From three long testing periods, 1935-1968, 1969-2010, and 1935-2010, all three hypotheses are confirmed based on the new estimate of beta. In other words there is a positive trade-off between average return and risk, and non-linearity and non-beta risk do not play a significant role in explaining the cross section of expected return. Test results from the three long periods based on the OLS beta and the Scholes-Williams beta are mixed and less supportive to CAPM. Our test results from the eight shorter periods do not confirm the CAPM. However, this may be due to the lack of power and efficiency of the test methodology when applied to short periods.^Overall, our results from long periods show that tests based on the new estimate of beta perform better than those based on the OLS beta and the Scholes-Williams beta in terms of supporting CAPM.
