Where ei is the initial endowment of tokens held by player i, xi is player is contribution, m is the share of the group contributions that each player receives andimage text in transcribed is the sum of all contributions by each of the players in the group. 3 Suppose you have a group of N = 4 players, each player has an initial endowment of 20, and m = 0.25 (contributions are shared equally among all members of the group). Show that if all other players contribute their entire endowment, player is optimal decision is to contribute nothing (to free-ride). Hint: Compare the payoff when player i contributes the full endowment to the payoff when player i contributes nothing. Also show the impact of player is decision on the other group members by comparing their payouts when player i free rides and when player i contributes their full endowment
