1.
Consider a two-period repeated game in which the stage game shown below is
played twice and the repeated-game payoffs are simply the sum of the payoffs in cach of the
two periods. Show that there exists a unique subgame perfect Nash equilibrium in which the
Nash equilibrium of the stage game is played in every period.

Consider a two-period repeated game in which the stage game shown below is
played twice and the repeated-game payoffs are simply the sum of the payoffs in each of the
two period. Find a subgame perfect reputational equilibrium in which players choose a non-
stage-Nash-equilibrium strategy in the first period? SHOW YOUR WORK.
