Book Description
This dissertation comprises three papers on the governance of corporate risk: 1. The first paper investigates the role of organizational structures aimed at monitoring corporate risk. Proponents of risk-related governance structures, such as risk committees or Enterprise Risk Management (ERM) programs, assert that risk monitoring adds value by ensuring that corporate risks are managed. An alternative view is that such governance structures are nothing more than window-dressing created in response to regulatory or public pressure. Consistent with the former view, I find that, in the period between 2000 and 2006, firms with more observable risk oversight structures exhibit lower equity and credit risk than firms with fewer or no observable risk oversight structures. I also provide evidence that firms with more observable risk oversight structures experienced higher returns during the worst days of the 2007-2008 financial crisis and were less susceptible to market fluctuations than firms with fewer or no observable risk oversight structures. Finally, I find that firms without observable risk oversight structures experienced higher abnormal returns to recent legislative events relating to risk management than firms with observable risk oversight structures. 2. The most common empirical measure of managerial risk-taking incentives is equity portfolio vega (Vega), which is measured as the dollar change in a manager's equity portfolio for a 0.01 change in the standard deviation of stock returns. However, Vega exhibits at least three undesirable features. First, Vega is expressed as a dollar change. This implicitly assumes that managers with identical Vega have the same incentives regardless of differences in their total equity and other wealth. Second, the small change in the standard deviation of returns used to calculate Vega (i.e., 0.01) yields a very local approximation of managerial risk-taking incentives. If an executive's expected payoff is highly nonlinear over the range of potential stock price and volatility outcomes, a local measure of incentives is unlikely to provide a valid assessment of managerial incentives. Third, Vega is measured as the partial derivative of the manager's equity portfolio with respect to return volatility. This computation does not consider that this partial derivative also varies with changes in stock price. The second paper develops and tests a new measure of managerial risk-taking equity incentives that adjusts for differences in managerial wealth, considers more global changes in price and volatility, and explicitly considers the impact of stock price and volatility changes. We find that our new measure exhibits higher explanatory power and is more robust to model specification than Vegafor explaining a wide range of measures of risk-taking behavior. 3. The third paper examines the relation between shareholder monitoring and managerial risk-taking incentives. We develop a stylized model to show that shareholder monitoring mitigates the effect of contractual risk-taking incentives on the manager's actions. Consistent with the model, we find empirically that the positive association between the CEO's contractual risk-taking incentives and risk-taking behavior decreases with the level of shareholder monitoring. Furthermore, consistent with the board anticipating and optimally responding to shareholder monitoring, boards of firms exposed to more intense monitoring design compensation contracts that provide higher incentives to take risks. Overall, our results suggest that, when evaluating risk-taking incentives provided by a compensation contract, it is important to account for the firm's monitoring environment.

Book Description
An introduction to the theory and methods of empirical asset pricing, integrating classical foundations with recent developments. This book offers a comprehensive advanced introduction to asset pricing, the study of models for the prices and returns of various securities. The focus is empirical, emphasizing how the models relate to the data. The book offers a uniquely integrated treatment, combining classical foundations with more recent developments in the literature and relating some of the material to applications in investment management. It covers the theory of empirical asset pricing, the main empirical methods, and a range of applied topics. The book introduces the theory of empirical asset pricing through three main paradigms: mean variance analysis, stochastic discount factors, and beta pricing models. It describes empirical methods, beginning with the generalized method of moments (GMM) and viewing other methods as special cases of GMM; offers a comprehensive review of fund performance evaluation; and presents selected applied topics, including a substantial chapter on predictability in asset markets that covers predicting the level of returns, volatility and higher moments, and predicting cross-sectional differences in returns. Other chapters cover production-based asset pricing, long-run risk models, the Campbell-Shiller approximation, the debate on covariance versus characteristics, and the relation of volatility to the cross-section of stock returns. An extensive reference section captures the current state of the field. The book is intended for use by graduate students in finance and economics; it can also serve as a reference for professionals.

Book Description
Academic finance has had a remarkable impact on many financial services. Yet long-term investors have received curiously little guidance from academic financial economists. Mean-variance analysis, developed almost fifty years ago, has provided a basic paradigm for portfolio choice. This approach usefully emphasizes the ability of diversification to reduce risk, but it ignores several critically important factors. Most notably, the analysis is static; it assumes that investors care only about risks to wealth one period ahead. However, many investors—-both individuals and institutions such as charitable foundations or universities—-seek to finance a stream of consumption over a long lifetime. In addition, mean-variance analysis treats financial wealth in isolation from income. Long-term investors typically receive a stream of income and use it, along with financial wealth, to support their consumption. At the theoretical level, it is well understood that the solution to a long-term portfolio choice problem can be very different from the solution to a short-term problem. Long-term investors care about intertemporal shocks to investment opportunities and labor income as well as shocks to wealth itself, and they may use financial assets to hedge their intertemporal risks. This should be important in practice because there is a great deal of empirical evidence that investment opportunities—-both interest rates and risk premia on bonds and stocks—-vary through time. Yet this insight has had little influence on investment practice because it is hard to solve for optimal portfolios in intertemporal models. This book seeks to develop the intertemporal approach into an empirical paradigm that can compete with the standard mean-variance analysis. The book shows that long-term inflation-indexed bonds are the riskless asset for long-term investors, it explains the conditions under which stocks are safer assets for long-term than for short-term investors, and it shows how labor income influences portfolio choice. These results shed new light on the rules of thumb used by financial planners. The book explains recent advances in both analytical and numerical methods, and shows how they can be used to understand the portfolio choice problems of long-term investors.

Book Description
This thesis consists of three essays on international finance. The first essay is "Exchange rates and Fundamentals". A new open interest rate parity condition that takes account of economic fundamentals is developed from stochastic discount factors (SDFs) of two countries. Through this parity condition, business cycles or fundamentals are linked to exchange rates. Key empirical findings from this parity condition are as follows. First, this model beats the random walk hypothesis: economic fundamentals explain exchange rate movements for high interest rate currencies. Exchange rates of low interest rate currencies act like a random walk because they are less correlated with fundamentals owing to their low risk. For example, U.S. business cycles explain the direction of changes in exchange rates against the dollar. The same thing is true for Japan. Second, this model resolves the forward premium puzzle: the forward premium puzzle is not a general characteristic as regarded in previous studies. It happens when the risk awareness of investors is low, during economic expansions and for low risk currencies. The second essay is "Carry Trade and Global Financial Instability". Carry trade, an opportunistic investment strategy that takes advantage of interest rate differential across countries, is identified the cause of the large-scale depreciations of peripheral currencies in the later half of 2008. A simultaneous equations model, which is derived from a conceptual partial equilibrium model for a local foreign exchange market, is estimated from a cross-sectional sample. The results suggest that the larger appreciation of the yen than the dollar was brought about by a lack of the local supply of the yen rather than a more severe crunch of yen credits. The third essay is "The Economic Origin of Letters of Credit". This essay discusses the economic origin of letters of credit, an instrument widely used in international trade. A game theoretical analysis shows that letters of credit improve efficiency in trade settlements, increasing returns in trade. A few notable facts on letters of credit are discussed. First, the new institution is adopted by merchant banks to maximize their profits and in the process, an improvement in efficiency of international transactions is obtained. Second, the organization established by the legacy institution, bills of exchange, played a critical role in adopting the new institution. Third, the legal enforcement is not essential in this economic institution. Finally, two drivers are identified that improve efficiency of transactions: concentration and projection.

Book Description
Doctoral Thesis / Dissertation from the year 2008 in the subject Business economics - Investment and Finance, grade: summa cum laude, European Business School - International University Schlo Reichartshausen Oestrich-Winkel, language: English, abstract: My doctoral thesis has the objective of broadening our understanding regarding the risk dynamics in capital markets. All three essays provide new evidence on how corporate investment decisions affect firm risk and how the adjustment process of risk can be described. Overall, my research documents the importance of understanding the dynamics of risk. Researchers, investors, and bank supervisors should bear in mind that corporate investment decisions may significantly affect firm risk. The assumption that risk remains constant over time may lead to incorrect conclusions.

Book Description
Winner of the prestigious Paul A. Samuelson Award for scholarly writing on lifelong financial security, John Cochrane's Asset Pricing now appears in a revised edition that unifies and brings the science of asset pricing up to date for advanced students and professionals. Cochrane traces the pricing of all assets back to a single idea—price equals expected discounted payoff—that captures the macro-economic risks underlying each security's value. By using a single, stochastic discount factor rather than a separate set of tricks for each asset class, Cochrane builds a unified account of modern asset pricing. He presents applications to stocks, bonds, and options. Each model—consumption based, CAPM, multifactor, term structure, and option pricing—is derived as a different specification of the discounted factor. The discount factor framework also leads to a state-space geometry for mean-variance frontiers and asset pricing models. It puts payoffs in different states of nature on the axes rather than mean and variance of return, leading to a new and conveniently linear geometrical representation of asset pricing ideas. Cochrane approaches empirical work with the Generalized Method of Moments, which studies sample average prices and discounted payoffs to determine whether price does equal expected discounted payoff. He translates between the discount factor, GMM, and state-space language and the beta, mean-variance, and regression language common in empirical work and earlier theory. The book also includes a review of recent empirical work on return predictability, value and other puzzles in the cross section, and equity premium puzzles and their resolution. Written to be a summary for academics and professionals as well as a textbook, this book condenses and advances recent scholarship in financial economics.
