Scenario
The French thinker, Jean Jacques Rousseau, presented the subsequent state of affairs. 2 hunters will either jointly hunt a stag (an adult deer and rather massive meal) or individually hunt a rabbit (tasty, however substantially less filling). searching stags is kind of difficult and needs mutual cooperation. If either hunts a stag alone, the prospect of success is minimal. searching stags is most useful for society however needs lots of trust among its members.
Description
There are 2 pure strategy equilibria. each players like one equilibrium to the opposite - it's each Pareto optimal and Hicks optimal. However, the inefficient equilibrium is a smaller amount risky because the payoff variance over the opposite player's methods is lower. Specifically, one equilibrium is payoff-dominant whereas the opposite is risk-dominant.
