Suppose that in a Hawk-Dove game similar to the one discussed in your workbook, the payoff to each player is -6 if both play Hawk. If both play Dove, the payoff to each player is 3, and if one plays Hawk and the other plays Dove, the one that plays Hawk gets a payoff of 8 and the one that plays Dove gets 0. In equilibrium, we would expect hawks and doves to do equally well. This happens when the proportion of the total population that plays Hawk is
A) .45.
B) .23.
C) .11.
D) .73.
E) 1.

In equilibrium, the expected payoffs for playing Hawk and Dove must be equal. Let p be the proportion of Hawks. The expected payoff for Hawk is p(-6) + (1-p)(8), and for Dove is p(0) + (1-p)(3). Setting these equal gives p = 0.45.
