incomplete information into a Bayesian game whose Nash equilibrium is called Bayesian Nash equilibrium... Formulation of Bayesian Games.[r]

3(a - e)/4, is greater than aggregate quantity in the Nash equilib- rium of the Cournot game, 2(a - e)/3, so the market-clearing price is lower in the Stackelberg game.. Thus, i[r]

(b) Let p be a probability that player 2 would choose Rock, and q be a probability that she chooses Paper. Note that her probability of choosing Scissors is written as 1 p q. Under mixed strategy Nash equilibrium, player 1 must be indi¤erent amongst choosing Rock, Paper and Scissors, which implies that these three actions must give him the same expected payo¤s. Let u R ; u P ; u S be his expected payo¤s by selecting

Ann and Bob are in an Italian restaurant, and the owner offers them a free 3- slice pizza under the following condition. Ann and Bob must simultaneously and independently announce how many slice(s) she/he would like: Let a and b be the amount of pizza requested by Ann and Bob, respectively (you can assume that a and b are integer numbers between 1 and 3). If a + b ≤ 3, then each player gets her/his requested demands (and the owner eats any leftover slices). If a + b > 3, then both players get nothing. Assume that each players payoff is equal to the number of slices of pizza; that is, the more the better.

2 units of the firm 1’s good and A − p 2 + p 1 2 units of the firm 2’s good. Assume that the firms have identical (and constant) marginal costs c(< A), and the payoff for each firm is equal to the firm’s profit, denoted by π 1 and π 2 .

Q = K 1 =4 L 1 =8 Then, answer the following questions. (a) In the short run, the …rm is committed to hire a …xed amount of capital K(+1), and can vary its output Q only by employing an appropriate amount of labor L . Derive the …rm’s short-run total, average, and marginal cost functions. (b) In the long run, the …rm can vary both capital and labor. Derive the …rm’s

(b) If consumer’s choice satis…es the weak axiom of revealed preferences, we can always construct a utility function which is consistent with such choice behav- iour. (c) If a consumer problem has a solution, then it must be unique whenever the consumer’s preference relation is convex.

The main theorem shows that the condition that a schools’ priority profile ≻ C has a common priority order for every type t ∈ T is sufficient for the existence of feasible assignments which are both fair and non-wasteful. This condition may be strong and hard to be satisfied when the classification of types is coarse. For instance, if the type set is {high income, low income} and there is a priority for students who live in each school’s walk zone, priority orders for high income students will differ across schools in general. However, this can be modified by making a finer type classification, {high income, low income} × {c 1 ’s walk zone, c 2 ’s walk zone,...}.
