2) Consider the problem of the upstream and downstream monopolist (pg
510 in Varian). Suppose the upstream monopolist faces a constant marginal
cost of MCupstream = 1. Suppose the upstream monopolist sells factor inputs
to the downstream monopolist at the price w. The downstream monopolist
faces the inverse demand p(y)
5 – y so that their marginal revenue is
M Rdownstream = 5 – 2y. In addition the downstream monopolist produces
output with the production function y = f(x) = x, where x are inputs pur-
chased from the upstream monopolist at a price w. Suppose the marginal
cost to the downstream monopolist is just w.(Hint: marginal revenue for the
upstream monopolist will be MRupstream = 5 – 4x)
a) Solve for x, y, w and p.
b) Suppose that the downstream monopolist purchased the firm of the up-
stream monopolist. What would be the new values of y and p be?
c) How are the answers different?
