In the town of Torrelodones, each of the N > 2 inhabitants has $100. They are told that they can all voluntarily contribute to a fund that will be evenly divided among all residents. If $ F are contributed to the fund, the local K-Mart will match the private contributions so that the total amount to be divided is $2 F . That is, each resident will get back a payment of $2 F/N when the fund is divided. If people in town care only about their own net incomes, in Nash equilibrium, how much will each person contribute to the fund?
