(h)(iii) A representative consumer has a utility function U (x, y) = xy. A representative firm makes good x and has a production function x = f(k, l) = (kl)0.25and an unavoidable fixed cost
equal to A. There are 100 consumers and, initially, 100 firms. Prices are w = v = Py = 1 and Px is determined in a competitive market. Representative consumer income is I = 2.
In the long run,the number of firms is M
(determined endogenously),
and is a variable.
(Hint: Long run supply in terms of M instead of 100, find new equilibrium in terms of M, and then use the profit condition).
(h)(iii) Given A = 1. Find the long run Px?

Suppose that a consumer’s utility function is U(x,y)=xy＋10y. the marginal utilities for this utility function are MUx=y and MUy=x＋10. The price of x is Px and the price of y is Py, with both prices positive. The consumer has income I. (this problem shows that an optimal consumption choice need not be interior, and may be at a corner point.) Assume first that we are at an interior optimum. Show that the demand schedule for x can be written as...
