The paper examines the tendency to sell winners and hold on to losers in a dynamic noisy rational expectations equilibrium with informed and uninformed investors. The key feature of the model is that the information asymmetry between investors varies over time. Besides demonstrating that the...

We construct and analyze a model of delegated portfolio management in which money managers signal their investment skills via their choice of transparency for their fund. We show that a natural equilibrium is one in which high- and low-skill managers pool in opaque funds, while medium-skill...

Complex investments are investments that are difficult to value in the short-term. In this paper, we analyze the incentives of a manager who is compensated based on short-term stock prices to invest in complex long-term investments. In particular, we explore how the manager's investment decision...

We study a model in which an issuer can manipulate information obtained by a credit rating agency (CRA). Better CRA screening reduces the likelihood of a high rating, but increases the value of a rated security. We find that improving the prior quality of assets can have no effect on the quality...

We show that firms may benefit from allowing some earnings management, because it can make noisy signals more informative. We model a firm that cannot observe a manager's cost of effort, her effort choice, and whether she manipulated a publicly observable signal. An optimal contract links...

The widespread use of accounting information by investors and financial analysts to help value stocks creates an incentive for managers to manipulate earnings in an attempt to influence short-term stock price performance. This paper examines the role of earnings management in affecting a firm's...

The paper examines the tendency to sell winners and hold on to losers in a dynamic noisy rational expectations equilibrium with informed and uninformed investors. The key feature of the model is that the information asymmetry between investors varies over time. Besides demonstrating that the...

This paper studies how relative wealth concerns, in which a person's satisfaction with their own consumption depends on how much others are consuming, affect investors' incentives to acquire information. We find that such externalities can generate complementarities in information acquisition...

An important trend in bank regulation is greater reliance on market discipline. In particular, information impounded in securities prices is increasingly used to complement supervisory activities of regulators with limited resources. The goal of this paper is to analyze the theoretical...

This paper investigates the relationship among a firm's managerial incentive scheme, the market liquidity of its shares, and its investment policy. It shows that the shareholders' concern about the effectiveness of stock-based compensation can lead to an overinvestment problem. However, unlike...
