Suppose that the preferences a typical American has for quantities of electricity (E) and gasoline (G) is given by U(E, G) = αln(E) + (1 − α)ln(G) where 0 < α < 1. Suppose the prices of gasoline and electricity in the units provided are both $1/unit and the consumer has an income of $100. Suppose in addition, the government has chosen to ration electricity by allowing 2 a maximum consumption of 50 units of electricity (E ≤ 50).

a. Suppose we discard the assumption that 0 < α < 1 and assume α > 1 instead, determine whether the given utility function U(E, G) = αln(E) + (1 − α)ln(G) is still a valid utility function.

b. Find a utility function with a different functional form that represents the same ordering of bundles as the given utility function U(E, G) does

c. If α = .25, find the optimal consumption bundle of gasoline and electricity.

d. If α = .75, find the optimal consumption bundle of gasoline and electricity.

e. Find the minimum value of α such that the rationing is binding

Lexicographic Preferences: Suppose that a consumer has lexicographic preferences over bundles of non-negative amounts of each of two commodities. The consumer’s consumption set is R2+. The consumer weakly prefers bundle a = (a1,a2) over bundle b = (b1,b2) if either (i) a1 > b1, or (ii) both a1 = b1 and a2 ? b2. In any other circumstance, the consumer does not weakly prefer bundle a to bundle b. (Note that these preferences are not continuous. Furthermore, they cannot be...

ii. Let G = (V, E) be a tree. Prove G has |V | − 1 edges using strong induction. Hint: In the inductive step, choose an edge (u, v) and partition the set vertices into two subtrees, those that are reachable from u without traversing (u, v) and those that are reachable from v without traversing (u, v). You will have to reason why these subtrees are distinct subgraphs of G. iii. What is the total degree of a...
