In MobLab we played the "Minimum Effort Game": 6 players are in one group, and each player has to choose an effort level e = 1, 2, 3, 4, 5, 6 or 7. The payoff was determined by the minimum effort level in their group and their own effort: Payoff = 2*minimum of all efforts in group - own effort level. For example, If the six group members put up effort levels (3, 4, 4, 4, 5, 7), then their respective payoffs are (3, 2, 2, 2, 1, -1). How many equilibria in "pure strategies", does this game have?
