A perfectly competitive industry consists of many identical firms, each with a long-run average total cost of LATC = 800 – 10Q + 0.1Q2 and long-run marginal cost of LMC = 800 – 20Q + 0.3Q2. Identify the region of economies of scale and diseconomies of scale.

    Consider a perfectly competitive market with many identical firms. Each firm has a long-run marginal cost function given by LRMC(y) = y ^2 + 1. We do not know the firms’ LRAT C function, but we know that at a quantity of 3 it is equal to LRMC. In other words: LRAT C(3) = LRMC(3). (a) Find an expression for an individual firm’s long-run inverse supply curve: this will be p as a function of y. Note that it will...

    6. Suppose that the trucking market is a perfectly competitive industry in long run equi librium. Each of the identical trucking firms has the same (long run) cost function: TC = 2250 + 10q2, where q is the volume of sales by each establishment. Each of the identical firms therefore have the same marginal cost: MC = 20q (a) What is the average cost function for the identical trucking firms? (b) How much does each individual firm produce in the...
