In the tutorial we have studied the 2-period alternating offer bargaining model with constant costs of delay. In other words, in that model, there were two agents 1 and 2 , each with a constant delay cost c1 and c2 respectively. That is the cost to each player i of each period of delay is ci . Now consider the 3 -period version of the model. In this model there are 3 periods t = 0, 1, 2 . As before the cost of each additional period of delay is ci to player i, i.e., if the period t = 2 proposal z = (z1, z2) is accepted then player i's payoff is zi 2ci and if the period t = 2 proposal is rejected, then it is (2c1, 2c2). Assume c1 > c2. Find a SPE of the game?
