Do people discriminate between co-ethnics and others in cooperative interactions? In an experiment in China, we find that participants in trust games send around 15% more to partners they know to be co-ethnics than to those whose ethnicity they do not know. Re- ceivers’ behavior is determined by...

This paper studies continuing optimal lockdowns (can also be interpreted as quaran-tines or self-isolation) in the long run if a disease (Covid-19) is endemic and immunity can fail, that is, the disease has SIRS dynamics. We model how disease related mor-tality affects the optimal choices in a...

Human interactions often involve a choice between acting selfishly (in ones' own interest) and acting prosocially (in the interest of others). Fast-and-slow models of prosociality posit that people intuitively favour one of these choices (the selfish choice in some models, the prosocial choice in...

The composition of the mutual fund industry changes through entry and exit over the business cycle. Entrants may on average be higher quality than exiting funds (a cleansing eect that improves welfare), but they have no returns history and so investors have less precise beliefs about their ability...

This paper considers linear panel data models where the dependence of the regressors and the unobservables is modelled through a factor structure. The asymptotic setting is such that the number of time periods and the sample size both go to infinity. Non-strong factors are allowed and the number of...

This paper studies point identification of the distribution of the coefficients in some random coefficients models with exogenous regressors when their support is a proper subset, possibly discrete but countable. We exhibit trade-offs between restrictions on the distribution of the random...

Autonomous Vehicles (AVs) promise of a multi-trillion-dollar industry that revolutionizes transportation safety and convenience depends as much on overcoming the psychological barriers to their widespread use as the technological and legal challenges. The first AV-related traffic fatalities have...

This paper studies the political sustainability of programs that are targeted towards the poor. Given that the poor to whom these programs cater do not constitute a majority, we show that for their own good it pays to let the middle class benefit from them in a random way. This approach mimics the...

We consider a general equilibrium model of international trade with two layers of informational asymmetries. Private information of Home producers on costs affects the design of ‘behind-the-border’ policies reflecting the political influence of inefficient producers. Home's supply is contracted,...
