An often-replicated result in the experimental literature on social dilemmas is that a large share of subjects reveal conditionally cooperative preferences. Cooperation generated by this type of preferences is notoriously unstable, as individuals reduce their contributions to the public good in...

When decisions are made before roles are assigned, the Dictator Game is strategically equivalent to a linear Public Goods Game. This suggests that, when played between individuals with the same income, the prosocial behavior observed may be attributed at least in part to reciprocal altruism....

A paradox is a proposition in (alleged) contrast with common sense. All science is replete with paradoxes. Economics is not an exception. This paper is focused on two widely discussed paradoxes: the Mandeville paradox (and the associated idea of an 'invisible hand') and the Prisoners' Dilemma...
