In this paper we develop a simple theoretical model to analyze the impact of institu- tional herding on asset prices. A growing empirical literature has come to the intriguing conclusion that institutional herding positively predicts short-term returns but nega- tively predicts long-term...

Recent studies show that single-quarter institutional herding positively predicts short-term returns. Motivated by the theoretical herding literature, which emphasizes endogenous persistence in decisions over time, we estimate the effect of multi-quarter institutional buying and selling on stock...

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 significant 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 ?nds that fund herding, de?ned as the tendency of a mutual fund to follow past aggregate institutional trades, is an important predictor of mutual fund performance. Examining actively managed U.S. equity mutual funds over the period 1990-2009, we ?nd that funds with a higher herding...

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...

We investigate how business ties with portfolio firms influence mutual funds’ proxy voting using a comprehensive dataset spanning 2003 to 2011. In sharp contrast to the prior literature, we show that the proxy voting of mutual funds is significantly influenced by their business ties with...

We provide a theoretical framework to study blockholder activism by funds who com- pete for investor ?ow. In our model, activists are intrinsically able to raise the value of target ?rms through monitoring. Competition for investor ?ow induces them to enhance the returns generated by monitoring...

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...

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...
