Using the traditional model of voluntary public good provision, it is shown that an expansion of group size exacerbates free riding tendencies as long as private consumption and the public good are strictly normal and weak gross substitutes. This result generalizes a previous Cobb-Douglas...

We present results from a repeated public goods experiment where subjects choose by vote one of two sanctioning schemes: peer-to-peer (informal) or centralized (formal). We introduce, in some treatments, a moderate amount of noise (a 10 percent probability that a contribution is reported...
