How to Find Nash Equilibrium

To find it, share each player’s strategy with every other player. If the players do not change their strategies, you have found the Nash equilibrium.

For eg, in the battle of the sexes scenario, draw a table with two rows and two columns. 

The vertical axis represents the woman’s options: ballet/prizefight and horizontal axis represents the man’s choices: also ballet /prizefight. In the top left quadrant, they both choose ballet (Nash Equilibrium). In the bottom right quadrant, they both choose prizefight (Nash Equilibrium). This table illustrates there are two possible Nash equilibria.
