Suppose the wheat market in Brazil is a perfectly competitive industry, where a representa- tive firm in this market has the long run total cost function TC(q) = 100+ q². The demand curve for wheat in Brazil is given by Q## = 600 – 10P. Finally, assume for now that, due to high tariffs, there are no imports of wheat into Brazil or exports of wheat out of Brazil. a) Derive a representative firm's marginal cost and average total cost functions. b) In the long-run equilibrium, how much wheat does a single firm produce? c) Derive the long run equilibrium price and quantity of the Brazilian wheat market.
