This paper studies the evolution of both characteristics of reciprocity - the willingness to reward friendly behavior and the willingness to punish hostile behavior. Firstly, preferences for rewarding as well as preferences for punishing can survive evolution provided individuals interact within...

We experimentally investigate the relevance of (asymmetric) outside options in ultimatum bargaining. Building on the generalized equity principle formulated by Selten (1978) we derive three different equity rules. These equity rules can explain 43% of all o ers. Our within-subject design allows...

Unpaid work, which falls outside of the national income accounts but within the general production boundary, is viewed as either "care" or as "work" by experts. This work is almost always unequally distributed between men and women, and if one includes both paid and unpaid work, women carry much...

We show that once interfamily exchanges are considered, Becker's rotten kids mechanism has some remarkable implications that have gone hitherto unnoticed. Specifically, we establish that Cornes and Silva's (1999) result of efficiency in the contribution game amongst siblings extends to a setting...

We use experimental data from variants of public good games to test for household efficiency among married couples in rural Uganda. Spouses frequently do not maximise surplus from cooperation and perform better when women are in charge of allocating the common pool. Women contribute less to this...
