Document Summary

Eco100y1 lecture 21 topic 10: monopoly ii. In monopolistic markets, firms have market power, they are price makers. On the graph, mr is steeper than p. When mr is negative or positive, the price effect and output effect are unbalanced. The solution to optimization in monopolies is found the same way they are in perfectly competitive markets, we find the optimal quantity at the intersection of the mc (marginal cost) and mr curves. At this quantity on the demand (d) curve, we find the price. Mc, mr and the shape of the d curve determine supply, there is no supply curve. Profit = (p atc) q. When a patent expires, qm (monopoly quantity) shifts to qc (competitive quantity), we concluded that the perfectly competitive market is more efficient because a higher q is sold at a lower p (atc = average total cost) Remember welfare economics, we look at the surplus. In the monopoly equilibrium, p > mr = mc.
