3.  In most endogenous growth models, allowing a monopolist to caplure no- nopolistic proft plays an important role in boosting innovation. Consider a monopolict facing a linear demand function: Q = a - 6P, and the marginal cost is constant at c. Parameters a, b, and c are positive constants with a - bc ＞ 0. Find the ratio of monopolistic proft to the total potential consumer surplus available if the good were priced at marginal cost.
