(d) The perfect Bayesian equilibrium puts NO restriction on beliefs at information sets that are not reached in equilibrium. (e) In the simple moral hazard problem we studied in class, the optimal wage (= s( )) is NOT necessarily increasing in outcome (= x).

Proof of Pratt’s Theorem (1) Sketch of the Proof. To establish (i) ⇔ (iii), it is enough to show that P is positively related to r. Let ε be a “small” random variable with expectation of zero, i.e., E(ε) = 0. The risk premium P (ε) (at initial wealth x) is defined by

Similarly, player 2 must be indi¤erent amongst choosing X and Y , which implies 4q + 6(1 q) = 7(1 q) , 5q = 1 , q = 1=5. Thus, the mixed-strategy equilibirum is that player 1 takes A with probability 1=5 (and B with probability 4=5) and player 2 takes X with probability 3=4 (and Y with probability 1=4).

(nw1) means student s prefers an empty slot at school c to her own assignment, and (nw2) and (nw3) mean that legal constraints are not violated when s is assigned the empty slot without changing other students’ assignments. The second property is about no-envy, which is also widely used in the context of school choice. But due to the structure of controlled school choice, as in Definition 1, even when a student prefers a school to her own and there is a student with lower priority in the school, the envy is not justified if the student’s move violates the legal constraints. Definition 2 formally states the condition for a student to have justified envy.

Players 1 (proposer) and 2 (receiver) are bargaining over how to split the ice-cream of size 1. In the first stage, player 1 proposes a share {x, 1 − x} to player 2 where x ∈ [0, 1] is player 1’s own share. Player 2 can decide whether accept the offer or reject it. If player 2 accepts, then the game finishes and players get their shares. If player 2 rejects, the game move to the second stage, in which the size of the ice-cream becomes δ(∈ (0, 1)) of the original size due to melting. In the second stage, by flipping a coin, the ice-cream is randomly assigned to one of the players. Suppose each player maximizes expected size of the ice-cream that she can get. Derive a subgame perfect Nash equilibrium of this game.

Eco 601E: Advanced Microeconomics II (Fall, 2nd, 2013) Final Exam: January 28 1. Dynamic Game (24 points) Consider the following two-person dynamic game. In the first period, game A is played; after observing each player’s actions, they play game B in the second period. Assume that the payoffs are simply the sum of the payoffs of two games (i.e., there is no discounting).

Three firms (1, 2 and 3) put three items on the market and can advertise these products either on morning (= M ) or evening TV (= E). A firm advertises exactly once per day. If more than one firm advertises at the same time, their profits become 0. If exactly one firm advertises in the morning, its profit is 1; if exactly one firm advertises in the evening, its profit is 2. Firms must make their daily advertising decisions simultaneously.

However, it is difficult to assess how reasonable some axioms are without having in mind a specific bargaining procedure. In particular, IIA and PAR are hard to defend in the abstract. Unless we can find a sensible strategic model that has an equilibrium corresponding to the Nash solution, the appeal of Nash’s axioms is in doubt.

DYNAMIC OLIGOPOLY AND COLLUSION Consider the Cournot duopoly model in Chapter 10, with two irms that each produce at zero cost (which I assume just to make the computations easy), and suppose the market price is given by p = 1 - ql - q2. Firm i, which produces qi, obtains a payof of (1 - qi - qj)qi' Note that the Nash equilibrium of this game is ql = q2 = 1/3, yielding a payoff of 1/9 for each irm. As noted in Chapter 10, this outcome is inefficient from the irms' point of view; they would both be better of if they shared the monopoly level of output by each produ;ing 1/4. Sharing the monopoly output yields each irm a payof of 1/8, which is greater than the Nash equilibrium payof of 1/9.1 In the static game, therefore, the firms would like to collude to set ql = q2 = 1/4, but this strategy proile cannot be sustained because it is not an equilibrium.
