Voluntary contributions when the public good is not necessarily normal

We argue that there are interesting examples of privately provided public g oods that do not satisfy the assumption of strict normality, and reconsider voluntary-contribution games in a more general framework. We show that, in general, (I) equalizing transfers between individuals with identical taste s can increase total supply of the public good, and (2) more of the public good can be supplied if agents move sequentially rather than simultaneously . These results are in sharp contrast to earlier conclusions derived in the literature under the assumption of strict normality.
