Students in some countries do far better on international achievement tests than students in other countries. Is this all due to differences in what students bring with them to school - socio-economic background, cultural factors, and the like? Or do school systems make a difference? This essay...

It is recognised that expressive preferences may play a major role in determining voting decisions because the low probability of being decisive in elections undermines standard instrumental reasoning. Expressive and instrumental preferences may deviate and in electoral settings it is more...

The aim of this paper is to examine the evolution of recruitment of elites and to investigate the nature of the links between recruitment of elites and economic growth. The main change that occurred in the way the Western world trained its elites is that meritocracy became the basis for their...

This paper offers an explanation for the widespread phenomenon of uniform public schooling, which is viewed here as a way for the government to precommit itself to restraints on future income redistribution. Such precommitment is likely to enhance accumulation of human capital, to bolster...

We investigate equilibrium impacts of federal policies such as free-college proposals, taking into account that human capital production is cumulative and that state governments have resource constraints. In the model, a state government cares about household welfare and aggregate educational...

This paper estimates the marginal returns to college for individuals induced to enroll in college by different marginal policy changes. The recent instrumental variables literature seeks to estimate this parameter, but in general it does so only under strong assumptions that are tested and found...

In Trinidad and Tobago students are assigned to secondary schools after fifth grade based on achievement tests, leading to large differences in the school environments to which students of differing initial levels of achievement are exposed. Using both a regression discontinuity design and...

Recent work shows that peers affect student achievement, but the mechanisms are not well understood. I show that peer behavior is an important mechanism, perhaps more so than ability, by exploiting exogenous timing in diagnosis/treatment of ADD among peers that improves peer behavior while...
