We suggest an alternative way of analyzing the canonical Bergstrom-Blume-Varian model of non-cooperative voluntary contributions to a public goodthat avoids the proliferation of dimensions as the number of players is in-creased. We exploit this approach to analyze models in which the...

We exploit the aggregative structure of the public good modelto provide a simple analysis of the voluntary contribution game. Incontrast to the best response function approach, ours avoids the pro-liferation of dimensions as the number of players is increased, andcan readily analyse games...
