We investigate experimentally whether the extent of conditional cooperation in public good games depends on the marginal return to the public good and type of game. The marginal return is varied from 0.2 to 0.4 to 0.8. The "standard" game, in which three players contribute before a follower, is...

We investigate experimentally whether the extent of conditional cooperation in public good games depends on the marginal per capita return (MPCR) to the public good and type of game. The MPCR is varied from 0.2 to 0.4 to 0.8. The "standard" game, in which three players contribute before a...

We provide a new proof of the non-emptiness of approximate cores of games with many players of a finite number of types. Earlier papers in the literature proceed by showing that, for games with many players, equal-treatment cores of their "balanced cover games", which are non-empty, can be...
