Hawk-Dove Game

Scenario

The hawk-dove game is also commonly known as the game of chicken. Two hooligans with something to prove drive at each other on a narrow road. The first to swerve loses faces among his peers. If neither swerves, however, a terminal fate plagues both. In the hawk-dove version of the tale, hooligans are replaced by armies considering going to war.

Description

There are two pure strategy equilibria. A different pure strategy equilibrium is preferred by each player. Both equilibria are Pareto optimal. A mixed strategy equilibrium also exists.

Example

Driver 2
stay swerve
Driver 1 stay -100,-100 1,-1
swerve -1,1 0,0

General Form
