u 2 (x, y 2 ) = 2 ln x + y 2 . u 3 (x, y 3 ) = 3 ln x + y 3 . (a) Assume that the public good is purchased, privately and that person 3 is the first to go to the market and buy the public good. Assume he does not act strategically; he ignores persons 1 and 2 when he buys x, and thinks only of his own utility maximization problem. What is the outcome? How much of the public good does person 3 buy? How much do persons 1 and 2 buy? (b) Use the Samuelson optimality condition to find the Pareto optimal quantity ### 最近の更新履歴 yyasuda's website

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 1s walk zone, c 2s walk zone,...}.

(c) There are two pure-strategy Nash equilibria: (A; X) and (B; Y ). (d) Let p be a probability that player 2 chooses X and q be a probability that player 1 chooses A. Since player 1 must be indi¤erent amongst choosing A and B, we obtain 2p = p + 3(1 p) , 4p = 3 , p = 3=4. ### PS2 1 solution 最近の更新履歴 yyasuda's website

Question 2 (5 points) (a) (i) No. Although her choice is not inconsistent with risk aversion, this infor- mation alone is not enough for us to judge if she is risk averse or not. (ii) Yes. Any risk loving agent must choose L 1 rather than for sure return of \$X when ### Lec1 最近の更新履歴 yyasuda's website

(c) Solving the consumer problem you derived in (b), find the competitive equi- librium allocation. (d) Assume that the government tries to achieve the equitable allocation, i.e., each consumer receives two units of both goods, through the market mechanism.

St Petersburg Paradox (1) The most primitive way to evaluate a lottery is to calculate its mathematical expectation, i.e., E[p] = P s∈S p(s)s. Daniel Bernoulli first doubt this approach in the 18th century when he examined the famous St. Pertersburg paradox.
