each prize s, where P s∈S p(s) = 1 (here p(s) is the objective
probability of obtaining the prize s given the lottery p). Let α ◦ x ⊕ (1 − α) ◦ y denote the lottery in which the prize x is realized with probability α and the prize y with 1 − α. Denote by L(S) the (infinite) space containing all lotteries

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,...}.

(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.

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.

(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
