In this note we provide conditions which ensure the existence of Nash networks in One-way flow models with cost heterogeneity.

If one assumes that voters are rational, the most plausible explanation for high voter turnouts seems to be that agents receive benefits from the act of voting itself. We show that public-spirited agents have an evolutionary advantage over those who are not as public-spirited for a range of...

The joint liability literature claims that positive assortative matching, or risk homogeneity, is always the first best solution. We examine this claim in presence of group formation costs and find that the assertion is not always true.

We extend the model of friendship networks developed by Brueckner (2006) in two ways. First, we extend the level of indirect benefits by incorporating benefits from up to three links and explore its implication for the socially optimal and individual effort levels. Next, we generalize the...

Female primates carry and nurse the fetus, and thus have the first responsibility for rearing the offspring. Assuming males are at least equally adept at obtaining food, males might either share surplus food with females or consume the food themselves. The distribution of this surplus is the...

The theory of equalising differences recognises that wage differentials may be required to equalise the attractiveness of alternative occupations. We examine this theory using the Conley/Wooders 'crowding types'' model. The crowding types model distinguishes between the tastes of a player and...
