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...

We introduce the concept of a parameterized collection of games with limited side payments, ruling out large transfers of utility. With convexity of the payoff set of the grand coalition, we show that (1) a game with limited side payments has a nonempty epsilon-core and (2) when some degree of...

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...
