Task

Suppose we have the following pay-off matrix.

  1. Find all Nash-equlibria in pure strategies
  2. Find the equilibrium in mixed strategies.

Solution

  1. {Theater; Theater} and {Football, Football}
  2. TA=0.2941, TB=0.70588

Task

Suppose we have the following situation. In a penalty shot in football, the goalkeeper can either jump to the right or left. The player can either kick to the right or the left. The pay-off matrix looks like follows:

  1. Find the Nash-equilibrium in pure strategies.
  2. Find the equilibria in mixed strategies for player and goal keeper.

Solution

  1. There is no Nash-equlibrium in pure strategies
  2. LS = 0,5, LT=0,5

Task

  1. Find the Nash-equilibrium in pure strategies.
  2. Find the equilibria in mixed strategies for player A and player B.

Solution

  1. Es gibt keines
  2. xA=0,8  IB=0,8

Task Rock-Paper-Scissors

  1. Find the equilibria in mixed strategies for player A and player B.

Solution

RA = SA = PA = 1/3

RB = SB = PB = 1/3

Task Matching Pennies
