Smith and Jones are stranded on a deserted island. Each has in her possession some slices of ham (H) and cheese (C). Smith prefers to consume ham and cheese in the fixed proportions of 2 slices of cheese to each slice of ham. Her utility function is given by Us = Min (10H, 5C). Jones on the other hand, regards ham and cheese to be perfect substitutes - she is always willing to trade 3 slices of ham for 4 slices of cheese, and her utility function is given by Uj = 4H + 3C. Total endowments are 100 slices of ham and 200 slices of cheese.
a. Draw the Edgeworth box diagram for all possible exchanges in this situation. What is the contract curve for this exchange?
b. Suppose smith's initial endowment is 40 slices of ham and 80 slices of cheese (jones gets the remaining ham and cheese as her initial endowment). what mutually beneficial trades are possible in this economy and what utility levels will smith and jones enjoy from such trades.
c. Suppose that 20 slices of ham could be transferred without cost from Jones' to Smith's endowment. Now what mutually beneficial trades might occur and what utility levels would be experienced by Smith and Jones?
