This paper considers the success of the Montreal Protocol on Substances that deplete the Ozone Layer in addressing an incompletely understood global environmental hazard under risk and uncertainty, and its implications for and interactions with other global environmental protection regimes,...

Using multiple datasets from different time periods, we document declines in academic time investment by full-time college students in the United States between 1961 and 2003. Full-time students allocated 40 hours per week toward class and studying in 1961, whereas by 2003 they were investing...

In 1961, the average full-time student at a 4-year college in the U.S. studied about 24 hours per week, while his modern counterpart puts in only 14 hours a week. Students now study less than half as much as universities claim to require. This dramatic decline in study times occurred for...

How robust are social preferences to variations in the environment in which a decision is made? By varying the elicitation method and default choice in the `moral wiggle-room' game of Dana, Weber, and Kuang (2007), I examine the robustness and nature of the pattern of information avoidance in...

This paper uses micro-level data on social networks in middle and secondary schools to estimate effects of connectedness on education attainment outcomes. The analysis addresses concerns about unobserved neighborhood and school-level heterogeneity by using within-school variation between grade...

Land can be inefficiently allocated when attempts to assemble separately-owned pieces of land into large parcels are frustrated by holdout landowners. The existing land-assembly institution of eminent domain can be used neither to gauge efficiency nor to determine how to compensate displaced...

College GPAs in the United States rose substantially between the 1960’s and the 2000’s. Over the same period, study time declined by almost a half. This paper uses a 12-quarter panel of course evaluations from the University of California, San Diego to discern whether a link...

Every abstract type of a belief-closed type space corresponds to an infinite belief hierarchy. But only finite order of beliefs is necessary for most applications. As we demonstrate, many important insights from recent development in the theory of Bayesian games with higher-order uncertainty...
