Book Description
In dealership markets, asymmetric information feeds through to higher transaction costs as dealers adjust their bid-ask spreads to compensate for anticipated losses. In this paper, we show that the presence of asymmetric information can also provide a positive externality to those market participants who operate in multiple markets-portfolio managers. Specifically, insiders lower the estimation errors of portfolio selection methods, thus improving asset allocation. We develop multiple artificial markets, in which portfolio managers trade alongside informed and uniformed speculators, and we contrast the performance of 'volatility timing' -- a method that relies on efficient price discovery -- with that of 'naive diversification'. Volatility timing is shown to consistently outperform naive diversification on a risk-adjusted basis.

Book Description
This dissertation studies the effects of asymmetric information and learning on asset prices and investor decision-making. Two main themes run through the work. The first is the linkage between investor decisions and the information used to make those decisions; that is, portfolio choices reflect the nature and quality of available information. The second theme is the interaction between investor learning and price informativeness. The information held by individual investors is reflected in market prices through their trading decisions, and prices thus transmit this information to other investors. In the first chapter, Asymmetric Information in Financial Markets: Anything Goes, I study a standard Grossman and Stiglitz (1980) noisy rational expectations economy, but relax the usual assumption of the joint normality of asset payoff and supply. The primary contribution is to characterize how the equilibrium relation between price and fundamentals depends on the way in which investors react to the information contained in price. My solution approach dispenses with the typical "conjecture and verify" method, which allows me to analytically solve an entire class of previously intractable nonlinear models that nests the standard model. This simple generalization provides a purely information-based channel for many common phenomena. In particular, price jumps and crashes may arise endogenously, purely due to learning effects, and observation of the net trading volume may be valuable for investors in the economy as it can provide a refinement of the information conveyed by price. Furthermore, the value of acquiring information may be non-monotonic in the number of informed traders, leading to multiple equilibria in the information market. I show also that the relation between investor disagreement and returns is ambiguous and depends on higher moments of the return distribution. In short, many of the standard results from noisy rational expectations models are not robust. I introduce monotone likelihood ratio conditions that determine the signs of the various comparative statics, which represents the first demonstration of the implicit importance of the MLRP in the noisy rational expectations literature. In the second chapter Do Fund Managers Make Informed Asset Allocation Decisions?, a joint work with Jacob S. Sagi, we derive a dynamic model in which mutual fund managers make asset allocation decisions based on private and public information. The model predicts that the portfolio market weights of better informed managers will mean revert faster and be more variable. Conversely, portfolio weights that mean revert faster and are more variable should have better forecasting power for expected returns. We test the model on a large dataset of US mutual fund domestic equity holdings and find evidence consistent with the hypothesis of timing ability, especially at three- to 12-month forecasting horizons. Nevertheless, whatever timing ability may be reflected in portfolio weights does not appear to translate into higher realized returns on funds' portfolios.

Book Description
In this volume, specialists from traditionally separate areas in economics and finance investigate issues at the conjunction of their fields. They argue that financial decisions of the firm can affect real economic activity—and this is true for enough firms and consumers to have significant aggregate economic effects. They demonstrate that important differences—asymmetries—in access to information between "borrowers" and "lenders" ("insiders" and "outsiders") in financial transactions affect investment decisions of firms and the organization of financial markets. The original research emphasizes the role of information problems in explaining empirically important links between internal finance and investment, as well as their role in accounting for observed variations in mechanisms for corporate control.

Book Description
"We examine the implications of portfolio theory for the cross-sectional behavior of equity trading volume. Two-fund separation theorems suggest a natural definition for trading activity: share turnover...We find strong evidence against two-fund separation, and a principal-components decomposition suggests that turnover is well approximated by a two-factor linear model" -- Abstract.

Book Description
Financial intermediaries play an important role in the pricing of financial assets. For example, intermediaries may act on behalf of consumers in deciding how their wealth is invested, or they may act as providers of liquidity. This dissertation explores several ways in which intermediaries impact price informativeness, the transaction costs investors incur, and investor welfare. In the first chapter, I examine how prices reveal information when intermediaries are informed. Using a model of repeated trade between a long-lived, informed, price-discriminating market maker and risk averse traders with endogenous hedging demands, I first show that traders are weakly better off trading with an informed dealer, as they may learn something about an asset's value in the process of transacting. Second, while long-term incentives can induce an informed market maker to honestly reveal information and increase risk-sharing, they also enable the market maker to hide her information and extract more rents, reducing price informativeness. This less desirable outcome dominates with respect to both the parameter space and a selection criterion. Finally, measures of market quality, such as the transient component of price volatility (illiquidity), may not accurately reflect welfare. The second chapter discusses how relationships affect prices when intermediaries are concerned about adverse selection. When counter-parties trade in OTC markets, such as those for corporate bonds or derivatives, the lack of anonymity implies that future terms of trade can influence prices today. Using a model of repeated trade between an informed trader and uninformed market makers, I show that information asymmetry can affect the markups charged by dealers in two ways. First, for a given market structure (number of market makers), traders with more private information incur lower trading costs because dealers offer better terms to mitigate adverse selection. Second, even when dealers can not compete directly on price quotes, they compete indirectly by improving the informed trader's outside option, though this competition is imperfect. While repeated trade allows two given counter-parties to ameliorate adverse selection, the maximum number of dealers, and hence the total gains achievable, are limited by information frictions. An empirical implication is that the comparative statics of transaction costs only make sense conditional on market structure. The third chapter considers the effect intermediaries have as financial advisors, and whether measures of their performance as mutual fund managers accurately reflect the value they add to an economy. Relative to the existing literature, I look at how the presence of mutual funds affects the price of the underlying asset in an economy. Once this pricing effect is accounted for, I show that standard measures of mutual fund performance may not accurately reflect whether fund management is welfare improving.

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.
