This study helps to explain why measured school inputs appear to have little effect on student outcomes, particularly for cohorts educated since 1960. Teachers' unionization can explain how public schools simultaneously can have more generous inputs and worse student performance. Using panel...

I identify the effects of class size on student achievement using longitudinal variation in the population associated with each grade in 649 elementary schools. I use variation in class size driven by idiosyncratic variation in the population. I also use discrete jumps in class size that occur...

School finance equalization has probably affected American schools more than any other reform of the last 30 years. Understanding it is a prerequisite for making optimal social investments in human capital. Yet, it is poorly understood. In this paper I explain why: it differs from conventional...

We present a method of ranking U.S. undergraduate programs based on students' revealed preferences. When a student chooses a college among those that have admitted him, that college "wins" his "tournament." Our method efficiently integrates the information from thousands of such tournaments. We...

This paper analyzes how organizations can minimize the costs of processing and communicating information. Communication is costly because it takes time for an agent to absorb new information sent by others. Agents can reduce this time by specializing in the processing of particular types of...

This paper analyzes the issue of commitment in S. Grossman and O. Hart's model of optimal labor contracts under asymmetric information about firm profitability. The author extends his framework by allowing employment to vary over time, at equidistant intervals. When both parties can precommit ex...

This paper shows how the optimal financial structure of a firm complements incentive schemes to discipline managers, and how the securities' return streams determine the claimholders' incentives to intervene in management. The theory rationalizes (1) the multiplicity of securities, (2) the...

This paper analyzes the relationship between the diffusion of new technologies and the decentralization of firms. Centralized control relies on the information of the principal, which we equate with publicly available information. Decentralized control, on the other hand, delegates authority to...
