Despite a large theoretical and empirical literature on public goods and common-pool resources, a systematic comparison of these two types of social dilemmas is lacking. In fact, there is some confusion about these two types of dilemma situations. As a result, they are often treated alike. In...

We investigate whether the gender composition of teams affects their economic performance.

Abdulkadiroglu et al. (2011) show that some naive participants may be better off under the Boston mechanism than under deferred acceptance. Here we show that under the veil of ignorance all naive students may prefer the Boston mechanism.

We study the computational complexity of rationalizing choice behavior. We do so by analyzing two polar cases, and a number of intermediate ones. In our most structured case, that is where choice behavior is defined in universal choice domains and satisfies the "weak axiom of revealed...
