Arrow’s Requirements of the SWF (1) Unrestricted Domain (UD) The domain of f must include all possible combinations of individual preference relations on X. Weak Pareto Principle (WP) For any pair of alternatives x and y in X, if xP i y for all i, then xP y.

(e) The social welfare function introduced by Arrow is to derive social UTILITY by adding up individual utilities. 2. Externalities (25 points) Consider a one-consumer, one-firm economy (or equiv- alently an economy with many identical consumers and firms.) There are two private commodities. The firm also produces a level of pollution b. The produc- tion set of the firm is the convex set γ = {(y 1 , y 2 , b | G(y 1 , y 2 , b ) ≤ 0)}, where G

(b) We will get (B; Z) in the following iterated elimination process: Step 1: We can erase X since X is strictly dominated by Z. Step 2: Given step 1, we can erase A since A is strictly dominated by B. Step 3: Given steps 1 and 2, we can erase Y since Y is strictly dominated by Z. (c) Any combinations of x and y that satisfy x + y = 100 are Nash equilibria. Clearly, there are 101 such equilibria, i.e., (0; 100)(1; 99):::(100; 0).

(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.

A bargaining situation is described by a tuple hX, D, % 1 , % 2 i: X is a set of possible agreements: a set of possible consequences that the two players can jointly achieve. D ∈ X is the disagreement outcome: the event that occurs if the players fail to agree.

(a) Derive firm 1’s payoff function and the best reply function. (b) Solve the pure-strategy Nash equilibrium of this game. How much profit does each firm earn? (c) Now suppose that firms decide prices sequentially: firm 1 sets its price p 1 first, and firm 2 chooses price only after observing firm 1’s price. Find the subgame perfect equilibrium of this game. How much profit does each firm earn?

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.

where u i (x, θ i ) is the money-equivalent value of alternative x ∈ X. This assumes the case of private values in which player i’s payoff does not depend directly on other players’ types. If it does, then it is called common values case. The outcome (of the mechanism) is described by
