Educational tracking seeks to group students by unobserved ability using measures of observable acquired skills. In a model where individuals have differential skills prior to beginning formal education due to differences in early childhood development (e.g. linguistic, cultural, or nutritional...

We show that too much meritocracy, modeled as accuracy of performance ranking in contests, can be a bad thing: in contests with homogeneous agents, it reduces output and is Pareto inefficient. In contests with sufficiently heterogeneous agents, discouragement and complacency effects further...

We extend Krugman's (1979) model of trade to multiple sectors or industries and show that, sector-by-sector, a bit of trade is worse than no trade at all. The reason is that the gains from the initiation of trade are second-order, while the welfare loss from the associated drop in varieties is...

This short paper extends the analysis of Morgan and Tumlinson (2018) to the setting of a small open economy. We show that in this economy featuring endogenous free entry of firms: (1) Both the number and production of firms is socially optimal. Furthermore production is efficient --- it...

Friedman (1970) suggests that firms ought not divert profits towards public goods since shareholders can better make these contributions themselves. Despite this, activist shareholders are increasingly successful in persuading firms to be "socially responsible." We study firm behavior when...
