Suppose that the only goods you consumed were wine and roses. On Monday, you consumed both wine and roses. On Tuesday, the price of wine goes up, and at the same time your income increases such that you are equally happy as you were on Monday. Assume that indifference curves are typical (i.e. convex). a. What happens to the quantity of wine that you consume on Tuesday, as compared to Monday? Use a graph with wine on the horizontal axis and roses on the vertical axis. b. On Tuesday, would you still be able to afford the same bundle that you were buying on Monday? Briefly explain how do you know? (Hint: Look at your graph in part a). c. On Wednesday there are no new price changes (so the Tuesday prices are still in effect), but your income changes to the point where you can just exactly afford Monday's bundle. Are you happier on Wednesday or Monday? Briefly explain. d. Is it possible to say with certainty whether you buy more wine on Wednesday than on Tuesday? Briefly say why or why not?
