In most countries, many of the largest corporations are controlled by large shareholders. We show that, under reasonable assumptions, this stylized fact implies that portfolio holdings of U.S. investors should exhibit a home bias in equilibrium. We construct an estimate of the world portfolio of...

This paper proposes an explanation of the international home bias in equity based on ambiguity aversion. Doubts imply an additional hedging motif driven by the interaction between real exchange rate risk and ambiguity aversion. What matters is the long-run as opposed to the short-run risk....

We investigate optimal consumption, asset accumulation and portfolio decisions in a realistically calibrated life-cycle model with flexible labor supply. Our framework allows for wage rate uncertainly, variable labor supply, social security benefits and portfolio choice over safe bonds and risky...

If an investor wants to form a portfolio of risky assets and can exert effort to collect information on the future value of these assets before he invests, which assets should he learn about? The best assets to acquire information about are ones the investor expects to hold. But the assets the...

This paper examines the dissemination of market timing information (signals on the overall performance of risky assets relative to the risk free rate). We consider two delivery systems. Under the newsletter delivery system market timing information is disseminated solely through newsletter....

A dynamic model of consumption and portfolio decisions is analyzed in which agents seek robust choices against some misspecification of the model probability distribution. This near-rational environment can at the same time explain an imperfect international portfolio diversification and break...

This paper develops a two-country monetary DSGE model in which households choose a portfolio of home and foreign equities, and a forward position in foreign exchange. Some goods prices are set without full information of the state. We show that temporarily sticky nominal goods prices can have...

People are more willing to bet on their own judgments when they feel skillful or knowledgeable (Heath and Tversky (1991)). We investigate whether this quot;competence effectquot; influences trading frequency and home bias. We find that investors who feel competent trade more often and have a...
