Suppose there is a monopolistically competitive market with n identical firms, such that each firm produces the same quantity, q. Further, the market is in the monopolistically competitive long-run equilibrium. You are given the following: Inverse market demand: P 10-Q Total market output: Qnxq Marginal revenue: MR 10n+ 1)xq Total cost: C(q)-5+q Marginal cost: MC 2xq In long-run equilibrium, each firm earns zero economic profit. In long-run equilibrium, the number of firms, n, is and each firm produces units) of...
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...
