What are the equilibrium features of a market where a sizeable portion of traders face career concerns? This question is central to our understanding of Þnancial markets that are increasingly dominated by institutional investors. We construct a model of delegated portfolio management that...

This paper shows that the systematic risk (or "beta") of individual stocks increases by an economically and statistically signi…cant amount on days of firm-specific news announcements, and reverts to its average level two to five days later. We employ intra-daily data and recent advances in...

This paper studies how the introduction of social learning with costs to delay affects coordination games with incomplete information. We present a tractable noisy dynamic coordination game with social learning and costs to delay. We show that this game has a unique monotone equilibrium. A...

Financial contagion is modeled as an equilibrium phenomenon in a dynamic setting with incomplete information and multiple banks. The equilibrium probability of bank failure is uniquely determined. We explore how the cross holding of deposits motivated by imperfectly correlated regional liquidity...

Do large investors increase the vulnerability of a country to speculative attacks in the foreign exchange markets? To address this issue, we build a model of currency crises where a single large investor and a continuum of small investors independently decide whether to attack a currency based...

Mutual funds hold large blocks of shares in many major corporations. Practitioners and regulators alike have been concerned that mutual funds use their proxy votes in a promanagement manner in order to garner lucrative pensions administration contracts, thus hindering shareholder value. Such...

We study how the presence of multiple participation opportunities coupled with individual learning about payoffs affects the ability of agents to coordinate efficiently in global coordination games. Two players face the option to invest irreversibly in a project in one of many rounds. The...

What determines the direction of spread of currency crises? We examine data on waves of currency crises in 1992, 1994, 1997, and 1998 to evaluate several hypotheses on the determinants of contagion. We simultaneously consider trade competition, financial links, and institutional similarity to...

In a model of career concerns for experts, when is a principal hurt from observing more information about her agent? This paper introduces a distinction between information on the consequence of the agent's action and information directly on the agent's action. When the latter kind of...
