Stock returns are correlated with contemporaneous earnings growth, dividend growth, future real activity, and other cash-flow proxies. The correlation between cash-flow proxies and stock returns may arise from association of cash-flow proxies with one-period expected returns, cash-flow news, and/or expected-return news. We use Campbell's (1991) return decomposition to measure the relative importance of these three effects in regressions of returns on cash-flow proxies. In some of the popular specifications, variables that are motivated as proxies for cash-flow news also track a nontrivial proportion of one-period expected returns and expected-return news. As a result, the R-super-2 from a regression of returns on cash-flow proxies may overstate or understate the importance of cash-flow news as a source of return variance.

This article models, and experimentally simulates, the free-rider problem in a takeover when the raider has the option to “resolicit,” that is, to make a new offer after an offer has been rejected. In theory, the option to resolicit, by lowering offer credibility, increases the dissipative losses associated with free riding. The outcomes of our experiment support this prediction and produce losses from free riding even higher than theoretically predicted. These dissipation losses reduce raider gains to less than 3% of synergy value of the acquisition

In this article, we provide a novel rationale for credit ratings. The rationale that we propose is that credit ratings serve as a coordinating mechanism in situations where multiple equilibria can obtain. We show that credit ratings provide a “focal point” for firms and their investors, and explore the vital, but previously overlooked implicit contractual relationship between a credit rating agency (CRA) and a firm through its credit watch procedures. Credit ratings can help fix the desired equilibrium and as such play an economically meaningful role. Our model provides several empirical predictions and insights regarding the expected price impact of rating changes.

We develop an equilibrium model in which exchange rates, stock prices and capital flows are jointly determined under incomplete forex risk trading. Incomplete hedging of forex risk, documented for U.S. global mutual funds, has three important implications: 1) exchange rates are almost as volatile as equity prices when the forex liquidity supply is not infinitely price elastic; 2) higher returns in the home equity market relative to the foreign equity market are associated with a home currency depreciation; 3) net equity flows into the foreign market are positively correlated with a foreign currency appreciation. The model predictions are strongly supported at daily, monthly and quarterly frequencies for 17 OECD countries visà-vis the U.S. Moreover, correlations are strongest after 1990 and for countries with higher market capitalization relative to GDP, suggesting that the observed exchange rate dynamics is indeed related to equity market development.

Investment banks imitate other bank's innovative corporate securities and compete with the innovator to underwrite new issues. This article uses data of all the corporate offerings of equity-linked and derivative securities in the Securities Data Company (SDC) to estimate the issuer's demand of underwriting services provided by investment banks across different varieties of securities. It finds that the demand for the innovator's variety is larger than the imitators'. This demand advantage decreases with time and faster for securities that appear later in a sequence of innovations. Imitation becomes less attractive later in the sequence as information from earlier deals spills-over to all banks. Copyright 2006, Oxford University Press.

This article illustrates an incentive-aligning role of debt in the presence of optimal compensation contracts. Owing to information asymmetry, value-maximizing compensation contracts allow managerial rents following high investment outcomes. The manager has an incentive to increase these rents by choosing investments that generate greater information asymmetry. An aptly chosen debt level mitigates this incentive, because investments that generate greater information asymmetry have more volatile outcomes. The greater volatility would make the debt risky, causing the shareholders to focus on high outcomes and therefore compensation contracts that reduce managerial rents. At the optimum, the manager avoids opportunistic investments, and the shareholders offer value-maximizing compensation contracts. Empirically, the analysis predicts a negative relationship between leverage and market-to-book that is reversed at extreme market-to-book ratios, a negative relationship between leverage and profitability, a negative relationship between leverage and pay-for-performance, and a positive relationship between pay-for-performance and investment opportunities.

We analyze a financially distressed owner-managed project. The main results of the model are: (1) borrower default is an endogenous response to the anticipated restructuring–foreclosure outcome; (2) the lender’s restructuring–foreclosure decision depends critically on the interaction between project value and industry liquidity; and (3) the lender waits for the industry to recapitalize before selling assets obtained through foreclosure. Empirical analysis of a large sample of defaulted commercial real estate loans supports many of the model predictions, including restructuring–foreclosure outcomes that are consistent with endogenous borrower default and firesale discounts that vary depending on industry market conditions at the time of foreclosure.

This article shows how the market coskewness model of Rubinstein (1973) and Kraus and Litzenberger (1976) is altered when a nonredundant call option is optimally traded. Owing to the option’s nonredundancy, the economy’s stochastic discount factor (SDF) depends not only on the market return and the square of the market return but also on the option return, the square of the option return, and the product of the market and option returns. This leads to an asset pricing model in which the expected return on any risky asset depends explicitly on the asset’s coskewness with option returns. The empirical results show that the option coskewness model outperforms several competing benchmark models. Furthermore, option coskewness captures some of the same risks as the Fama–French factors small minus big (SMB) and high minus low (HML). These results suggest that the factors that drive the pricing of nonredundant options are also important for pricing risky equities.(JEL G11, G12, D61)

An experimental approach is used to examine the performance of three different multiunit auction designs: discriminatory, uniform-price with fixed supply, and uniform-price with endogenous supply. We find the actual strategies to be inconsistent with theoretically identified equilibrium strategies. The discriminatory auction is found to be more susceptible to collusion than either uniform-price auction and so, contrary to theoretical predictions and previous experimental results, it generates the lowest average revenue. Consistent with theoretical predictions, the actual bid schedules are more elastic with reducible supply or discriminatory pricing than in the uniform-price auction with fixed supply.

We derive a closed-form solution for the optimal portfolio of a nonmyopic utility maximizer who has incomplete information about the alphas or abnormal returns of risky securities. We show that the hedging component induced by learning about the expected return can be a substantial part of the demand. Using our methodology, we perform an “ex ante” empirical exercise, which shows that the utility gains resulting from optimal allocation are substantial in general, especially for long horizons, and an “ex post” empirical exercise, which shows that analysts’ recommendations are not very useful.
