We study the investment behavior of foreign investors in association with an equity market liberalization, and find a strong link between foreigners trading and local market returns. In the period following the liberalization, net purchases by foreign investors induced a permanent increase in stock prices, suggesting that local firms reduced their cost of equity capital. We also find a strong l...

We develop a finite horizon continuous time market model, where risk averse investors maximize utility from terminal wealth by dynamically investing in a risk-free money market account, a stock, and a defaultable bond, whose prices are determined via equilibrium. We analyze the endogenous interaction arising between the stock and the defaultable bond via the interplay between equilibrium behavi...

This paper investigates the performance of efficient portfolios in a financial market with heterogeneous investors including rational traders, noise traders, and chartists. A generalization of the security market line result states that, regardless of the diversity of beliefs, the portfolios of rational investors with mean-variance preferences are mean-variance efficient in the sense of classic...

This paper looks at the effect of shareholder horizon on corporate behavior. In perfect capital markets, corporate behavior should be insensitive to shareholder horizon, but when investment opportunities are not well valued by the market, shareholder horizon matters. We first present a simple framework to show that shareholder horizon should be looked at in conjunction with stock misvaluation. ...

This work offers a theoretical explanation of the electronic commerce stock market bubble of 1999-2000. We propose that the bubble existed because a lack of good information about the potential value of electronic commerce led investors to rely on one another’s private valuations of electronic commerce. Because each investor relied on other investors, positive information early in the period wa...

The assumption that mood affects investors’ behavior in the field is gaining acceptance due to experimental studies and papers linking stock returns with environmental variables, such as weather and length of day. To identify mood effects this paper utilizes account level stock trading data from all investors in Finland, a country with significant variation in weather and length of day. While s...

Short-termism need not breed informational price inefficiency even when generating Beauty Contests. We demonstrate this claim in a two-period market with persistent liquidity trading and risk-averse, privately informed, short-term investors and find that prices reflect average expectations about fundamentals and liquidity trading. Informed investors engage in “retrospective” learning to reasses...

The US Security and Exchange Commission implemented Regulation Fair Disclosure in 2000, requiring that an issuer must make relevant information disclosed to any investor available to the general public in a fair manner. Focusing on firms that are affected by the regulation, we propose a model that characterizes the behavior of two types of investors—one professional investor and many small inve...
