Thm An aggregate production plan y maximizes aggregate profit, if and only if each firm’s production plan y j maximizes its individual profit for all j ∈ J. The theorem implies that there are two equivalent ways to construct the aggregate net supply function:

  4. Incomplete Information (16 points, think carefully)  There are four different bills, $1, $5, $10, and $20. Two individuals randomly receive  one bill each. The (ex ante) probability of an individual receiving each bill is therefore  1/4.  An individual knows only her own bill, and  is  simultaneously given the option of  exchanging her bill for the other individual’s bill. The bills will be exchanged if and only  if  both  individuals  wish  to  do  so;  otherwise  no  exchange  occurs.  That  is,  each  individuals can choose either exchange (E) or not (N), and exchange occurs only when  both  choose  E.  We  assume  that  individuals’  objective  is  to  maximize  their  expected  monetary payoff ($).

(a) If an agent is risk averse, her risk premium is ALWAYS positive. (b) When every player has a (strictly) dominant strategy, the strategy profile that consists of each player’s dominant strategy MUST be a Nash equilibrium. (c) If there are two Nash equilibria in pure-strategy, they can ALWAYS be Pareto
