  1. Course Description    This  is  an  introductory  course  in  game  theory,  which  will  provide  you  with  mathematical  tools  for  analyzing  strategic  situations  ‐  your  optimal  decision  depends  on what other people will do. In particular, we will study central solution concepts in  game  theory  such  as  Nash  equilibrium,  subgame  perfect  equilibrium,  and  Bayesian  equilibrium. Game theory has been widely recognized as an important analytical tool  in such fields as economics, management, political science, phycology and biology. To  illustrate  its  analytical  value,  we  will  cover  a  variety  of  applications  that  include  international relations, development, business competition, auctions, marriage market,  and  so  forth.  There  is  no  prerequisite  for  this  course,  although  some  background  on  microeconomics and familiarity of probabilistic thinking would be helpful.

(5) Suppose that this game is played finitely many times, say T (≥ 2) times. De- rive the subgame perfect Nash equilibrium of such a finitely repeated game. Assume that payoff of each player is sum of each period payoff. (6) Now suppose that the game is played infinitely many times: payoff of each player is discounted sum of each period payoff with some discount factor δ ∈ (0, 1). Assume specifically that A = 16, c = 8. Then, derive the condition under which the trigger strategy sustains the joint-profit maximizing prices you derived in (3) (as a subgame perfect Nash equilibrium).

You all dislike cleaning, but you all like having a clean apartment: each person i’s payoff is the total hours spent (by everyone) cleaning, minus a number c (> 0) times the hours spent individually cleaning.

C) Now suppose that the rule of the game is modified as follows. If exchange occurs,  each  individual  receives  3  times  as  much  amount  as  the  bill  she  will  have.  For  example, if individual 1 receives $5 and 2 receives $10 initially and both wish to  exchange,  then  1  will  receive  $30  (=  $10  x  3)  and  2  will  receive  $15  (=  $5  x  3).  Nothing  happens  if  they  do  not  exchange.  Then,  does  trade  occur  in  a  Bayesian  Nash equilibrium? Explain.
