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

This Paper shows that trade can occur in a market where all traders are rational and none of them is subject to exogenous shocks. We develop a model of delegated portfolio management that captures key features of the US mutual fund industry and we embed it into an asset-pricing set-up. Fund...

What are the equilibrium features of a dynamic financial market where traders care about their reputation for ability? We modify a standard sequential trading model to study a financial market with career concerns. We show that this market cannot be informationally efficient: there is no...

Mutual funds are significant blockholders in many corporations. Concerns that funds vote in a pro-management manner to garner lucrative pensions contracts led the SEC to mandate the disclosure of proxy votes. We present a model of mutual fund voting in the presence of potential business ties. We...

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...

We provide a theoretical model to explain the procyclicality of hedge fund activism. In our model, hedge funds which compete to retain investor flows excessively increase the net leverage of target firms in order to deliver high short-term payouts and signal their ability. Such excessive...

We provide evidence on the match between firms, managers and incentives using a new survey designed for this purpose. The survey contains information on a sample of executives' risk preferences and human capital, on the explicit and implicit incentives they face and on the firms they work for....

This paper investigates the role of campaign advertising and the opportunity of legal restrictions on it. An electoral race is modeled as a signalling game with three classes of players: a continuum of voters, two candidates, and one interest group. The group has non-verifiable insider...

We propose a distinction between active waste and passive waste as determinants of the cost of public services. Active waste entails utility for the public decision maker (as in the case of bribery) whereas passive waste does not (as in the case of inefficiency due to red tape). To assess the...

A code is a technical language that members of an organization learn in order to communicate among themselves and with members of other organizations. What are the features of an optimal code and how does it interact with the characteristics of the organization? This Paper develops a simple...
