vNM Utility Function (1) Note the function U is a utility function representing the preferences on L(S) while v is a utility function defined over S, which is the building block for the construction of U (p). We refer to v as a vNM (Von Neumann-Morgenstern) utility function.

6. General Equilibrium (30 points) Consider a production economy with two individuals, Ann (A) and Bob (B), and two goods, leisure x 1 and a consumption good x 2 . Ann and Bob have equal en- dowments of time (= ω 1 ) to be allocated between leisure and work, so the total

Suppose that consumer i has preferences over the contingent consumption plans that satisfy expected utility hypothesis: U i (x i 1 , x i 2 ) = π 1 u i (x i 1 ) + π 2 u i (x i 2 ) where π 1 (π 2 ) is the objective probability of nice (bad) weather.

Pareto Efficiency (1) A situation is called Pareto efficient if there is no way to make someone better off without making someone else worse off. That is, there is no way to make all agents better off. To put it differently, each agent is as well off as possible, given the utilities of the other agents.

Second Welfare Theorem (1) Theorem 12 Consider an exchange economy with P i∈I e i ≫ 0, and assume that utility function u i is continuous, strongly increasing, and strictly quasiconcave for all i ∈ I. Then, any Pareto efficient allocation x is a competitive equilibrium allocation when endowments are redistributed to be equal to x.

Second Welfare Theorem Theorem 9 Suppose the conditions stated in the existence theorem are satisfied. Let (x ∗ , y ∗ ) be a feasible Pareto efficient allocation. Then, there are income transfers, T 1 , ..., T I , satisfying P i∈I T i = 0, and a price vector p such that for all j ∈ J and for all i ∈ I.
