Book Description
This dissertation consists of two essays on disaster risk and equity return predictability. The first essay proposes new measures of firm-level and market level disaster risk from deviation of put-call symmetry, which is free from being contaminated by the asymmetry between option traders and equity investors. Compared with other known measures of disaster risk, the market-level disaster risk measure robustly predicts aggregate market returns, with out-of-sample (R^2=6.86%) for the next twelve months. The cross-sectional analysis shows that firm-level disaster risk also explains variations in expected stock returns. Stocks with high firm-level disaster risk earn an annual four-factor subsequent alpha 8.0% higher than stocks with low firm-level disaster risk. I explore potential mechanisms giving rise to these asset pricing facts. The second essay finds that the investor’s learning of higher moments can account for the time-variation, size, and volatility of equity premium. I estimate the investor’s belief on skewness and kurtosis of consumption and dividend growth, and assume investor’s Bayesian learning about a skew student’s t-distribution with unknown fixed parameters. The predictive regressions show that more negative skewness and higher kurtosis predict higher subsequent market excess returns, which implies the investor’s learning generates the time variation of equity premium although the true distribution is static. The calibrated asset pricing model shows that the investor’s learning also explains the size and volatility of the equity premium observed in the data when the investor has a preference for early resolution of uncertainty.

Book Description
After laying dormant for more than two decades, the rare disaster framework has emerged as a leading contender to explain facts about the aggregate market, interest rates, and financial derivatives. In this paper we survey recent models of disaster risk that provide explanations for the equity premium puzzle, the volatility puzzle, return predictability and other features of the aggregate stock market. We show how these models can also explain violations of the expectations hypothesis in bond pricing, and the implied volatility skew in option pricing. We review both modeling techniques and results and consider both endowment and production economies. We show that these models provide a parsimonious and unifying framework for understanding puzzles in asset pricing.

Book Description
My research field is asset pricing with a focus on return predictability, innovation and market efficiency, and delegated investment management. In Chapter 1, "Maximum Return Predictability", I develop two theoretical upper bounds on the R2 of the regression of stock returns on predictive variables. Empirically, I found that the predictive R2s are significantly larger than the upper bounds, implying that existing asset pricing models are incapable of explaining the degree of return predictability. For example, the predictive R2 of the price dividend ratio for the U.S. market forecasting is 0.27% with monthly data. However, the theoretical upper bound is at most 0.07% with respect to CAPM, Fama-French three-factor model, CARA, habitat-formation model, long-run risk model, or rare disaster model. The finding of this paper suggests the development of new asset pricing models with new state variables that are highly correlated with stock returns. Recently, several papers found that the predictive power of almost all the existing macroeconomic variables exists only during economic recessions but does not exist over economic expansions. There perhaps have two reasons. First, existing predictors are individual economic variables and cannot capture the dynamics of the whole market. Second, the recognized predictive regression does not distinguish the varying ability of macro variables in forecasting the financial market. In Chapter 2, "Economic and Market Conditions: Two State Variables that Predict the Stock Market," Guofu Zhou and I identify two new predictors that capture the state of the economy and the state of the market condition, and found that the forecast of the market risk premium by the two predictors outperform a pooled forecast of dozens of existing predictors. Moreover, they forecast the stock market not only during down turns of the economy, but also during the up turns when other predictors fail. In decentralized investment management, there is always a friction between the principal and the manager. In Chapter 3, "The Servant of Two Masters: A Common Agency Explanation for Side-by-Side Management," I present a common agency model to study side-by-side (SBS) management in which a manager simultaneously manages two funds and separately contracts with the two different fund principals. The contracting is decentralized and includes two types of externalities: the manager's efforts are substitutable and the performance in one fund can generate a spillover effect on the other fund. The two principals can choose competition or free-riding. Under public contracting, competition is more likely to dominate free-riding. Under private contracting, however, free-riding becomes more important. In either case, SBS could generate better performance than standalone management.

Book Description
Recent studies have shown that disaster risk can generate asset return moments similar to those observed in the U.S. data. However, these studies have ignored the cross-country asset pricing implications of the disaster risk model. This paper shows that standard U.S.-based disaster risk model assumptions found in the literature lead to counterfactual international asset pricing implications. Given consumption pricing moments, disaster risk cannot explain the range of equity premia and government bill rates nor the high degree of equity return correlation found in the data. Moreover, the independence of disasters presumed in some studies generates counterfactually low cross-country correlations in equity markets. Alternatively, if disasters are all shared, the model generates correlations that are excessively high. We show that common and idiosyncratic components of disaster risk are needed to explain the pattern in consumption and equity co-movements.

Book Description
We investigate how corporate stock returns respond to geopolitical risk in the case of South Korea, which has experienced large and unpredictable geopolitical swings that originate from North Korea. To do so, a monthly index of geopolitical risk from North Korea (the GPRNK index) is constructed using automated keyword searches in South Korean media. The GPRNK index, designed to capture both upside and downside risk, corroborates that geopolitical risk sharply increases with the occurrence of nuclear tests, missile launches, or military confrontations, and decreases significantly around the times of summit meetings or multilateral talks. Using firm-level data, we find that heightened geopolitical risk reduces stock returns, and that the reductions in stock returns are greater especially for large firms, firms with a higher share of domestic investors, and for firms with a higher ratio of fixed assets to total assets. These results suggest that international portfolio diversification and investment irreversibility are important channels through which geopolitical risk affects stock returns.

Book Description
Natech Risk Assessment and Management: Reducing the Risk of Natural-Hazard Impact on Hazardous Installations covers the entire spectrum of issues pertinent to Natech risk assessment and management. After a thorough introduction of the topic that includes definitions of terms, authors Krausmann, Cruz, and Salzano discuss various examples of international frameworks and provide a detailed view of the implementation of Natech Risk Management in the EU and OECD. There is a dedicated chapter on natural-hazard prediction and measurement from an engineering perspective, as well as a consideration of the impact of climate change on Natech risk. The authors also discuss selected Natech accidents, including recent examples, and provide specific ‘lessons learned’ from each, as well as an analysis of all essential elements of Natech risk assessment, such as plant layout, substance hazards, and equipment vulnerability. The final section of the book is dedicated to the reduction of Natech risk, including structural and organizational prevention and mitigation measures, as well as early warning issues and emergency foreword planning. Teaches chemical engineers and safety managers how to safeguard chemical processing plants and pipelines against natural disasters Includes international regulations and explains how to conduct a natural hazards risk assessment, both of which are supported by examples and case studies Discusses a broad range of hazards and the multidisciplinary aspects of risk assessment in a detailed and accessible style
