For both practitioners and researchers, span of control plays an important role in defining and understanding the role of the CEO. In this paper, we combine organizational chart information for a sample of 65 companies with detailed data on how their CEOs allocate their work time, which we...

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...

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...

We study delegated portfolio management when the agent controls the riskiness of the portfolio. Under general conditions, we show that the optimal contract is simply a bonus contract: the agent is paid a fixed sum if the portfolio return is above a threshold. We derive a criterion to decide...

Equilibrium of the housing market depends on a complex set of interactions between: (1) individual location decisions; (2) individual housing investment; (3) collective decisions on urban growth. We embed these three elements in a model of a dynamic economy with two sources of friction:...

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

We develop a methodology to collect and analyze data on CEOs' time use. The idea — sketched out in a simple theoretical set-up — is that CEO time is a scarce resource and its allocation can help us identify the firm's priorities as well as the presence of governance issues. We follow 94 CEOs...

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....

We develop a new survey instrument to codify CEOs' diaries in large samples and use it to measure the labor supply of 1,114 family and professional CEOs of manufacturing firms across six countries (Brazil, France, Germany, India, the United Kingdom and the United States). By this measure, family...

CEOs affect the performance of the firms they manage, and family CEOs seem to weaken it. Yet little is known about what top executives actually do, and whether it differs by firm ownership. We study CEOs in the Indian manufacturing sector, where family ownership is widespread and the...
