Nicholson, Microeconomic Theory, Chapter 5, pp. 177-178. 1. Suppose that an individual's utility function is given by a. b. U(x,y) = 2xy + 2y x, y> 0 Express the CP for this consumer and solve for the ordinary (Marshallian) demand functions for X and Y. Show how these demand functions are shifted by changes in income or by changes in the price of the opposite good (cross price). (And interpret!) C. Show that the demand function for good Y is homogeneous of degree 0 in (p,m). d. Find the consumer's indirect utility function. e. Find the consumer's expenditure function as a solution to DCP.
