We investigate behavioral responses to a staggered disruption in the supply of prescription opioids across U.S. states: the introduction of electronic Prescription Drug Monitoring Programs (PDMPs). Using administrative datasets, we find PDMPs curtail the proliferation of prescription opioids....

The prisoner's dilemma (PD) is arguably the most important model of social dilemmas, but our knowledge about how a PD’s material payoff structure affects cooperation is incomplete. In this paper we investigate the effect of variation in material payoffs on cooperation, focussing on one-shot PD...

This paper studies optimal sport league size. League expansion lowers average player quality, reducing fans utility in inframarginal locations, while fan utility in new locations rises. Welfare analyses of such expansions must compare these two effects. Using a model where fan demand depends on...

This paper develops a model of the war against illegal drugs in both producer and consumer countries. The paper studies the trade-off faced by the government of the drug consumer country between prevention policies (aimed at reducing the demand for drugs) and enforcement policies (aimed at...

I consider transactions involving asymmetric prisoners dilemmas between pairs of players selected chosen from two large populations. Games are played repeatedly, but information about cheating is not adequate to sustain cooperation, and there is no official legal system of contract enforcement....
