Marty purchases two goods, food and clothing. He has a diminishing marginal rate of substitution of food for clothing. Let x indicate the amount of food consumed and y the amount of clothing. Suppose the price of food increases from P, to P2. On a clearly labeled graph, illustrate the income and substitution effects for each of the following scenarios: a) Food is a normal good. b) The income elasticity of food is zero (i.e. Marty's consumption of food does not change in response to his income). c) Food is an inferior good, but not a Giffen good. This question is based on problem 5.9 from Besanko and Breautigam. You can (but don't have to) assume that Marty's consumer choice problem has an interior solution both before and after the price change.
