The Internet globalizes the world. National regulatory autonomy shrinks. Transferring data from one country to another is almost costless. Foreign content is just a click away. Why is it that states have been able to re-install co-existence in some policy areas, and not in others? In data...

We examine how overall delivery of public goods (i.e., efficiency) is affected by affirmative action in elections, i.e., restricting candidate entry in elections to one population group. We argue that when group identities are salient, such restrictions on candidate entry need not necessarily...

In a family context with endogenous timing, multiple public goods and alternative parental instruments, we show that the optimal timing for the sequential-action game played by rotten kids and a parent depends crucially on whether the kids are homogeneous or heterogeneous. For homogeneous kids,...

Policies and explicit private incentives designed for self-regarding individuals sometimes are less effective or even counterproductive when they diminish altruism, ethical norms and other social preferences. Evidence from 51 experimental studies indicates that this crowding out effect is...

There are many reasons to suspect that benefit-cost analysis applied to environmental policies will result in policy decisions that will reject those environmental policies. The important question, of course, is whether those rejections are based on proper science. The present paper explores...

Policies and explicit incentives designed for self-regarding individuals sometimes are less effective or even counterproductive when they diminish altruism, ethical norms and other social preferences. Evidence from 51 experimental studies indicates that this crowding out effect is pervasive, and...

In both experimental and natural settings incentives sometimes under-perform, generating smaller eects on the targeted behaviors than would be predicted for entirely self-regarding agents. A parsimonious explanation is that incentives that appeal to payo maximizing mo- tives may crowd out...
