We present a lab-field experiment designed to assess systematically the external validity of social preferences elicited in a variety of experimental games. We do this by comparing behavior in the different games with a number of behaviors elicited in the field and with self-reported behaviors...

We consider a set of agents who have to choose one alternative among a finite set of social alternatives. A final allocation is a pair given by the selected alternative and the group of its users. Agents have crowding preferences over allocations: between any pair of allocations with the same...

Equivalence classes of normal form games are defined using the discontinuities of correspondences of standard equilibrium concepts like correlated, Nash, and robust equilibrium, or risk dominance and rationalizability. Resulting equivalence classes are fully characterized and compared across...
