Suppose Jane has u(A,B) = 5A+B, and K has u(A,B) = 8A+B. Jane and Kristen make an exchange where Jane loses 1A and gains x amount of B, and Kristen gains 1A and loses x amount of B. What values of x make this exchange a Pareto improvement?

Suppose Joe's utility for lobster (L) and soda (S) can be represented as U = L0.5 S0.5. Draw the indifference curve that yields a utility level of 9. Calculate the MUL, MUS, and MRS of L for S on that indifference curve when S = 3. Teddy has preferences given by the utility function U(K,L) = 2L + K where K = pounds of Kale per month and L = pounds of lettuce per month. What is Teddy's Marginal Utility...

Suppose that Elizabeth has a utility function U= (or U=W^(1/3) ) where W is her wealth and U is the utility that she gains from wealth. Her initial wealth is $1000 and she faces a 25% probability of illness. If the illness happens, it would cost her $875 to cure it. What is Elizabeth’s marginal utility when she is well? And when she is sick? Is she risk-averse or risk-loving? What is her expected wealth with no insurance? What is...
