9.6 The Case of a Foreign Monopoly LEARNING OBJECTIVES 1. Learn that a foreign monopoly supplying products to domestic consumers is a type of market imperfection. 2. Recognize that a trade policy can be used to correct for a foreign monopolist imperfection. 3. Learn the first-best and second-best policy options to correct for a foreign monopolist imperfection. Consider a domestic market supplied by a foreign monopoly firm. The domestic market consists of many consumers who demand the product but has no domestic producers of the product. All supply of the product comes from a single foreign firm. Saylor URL: http://www.saylor.org/books Saylor.org 475
Although this situation is not very realistic, it is instructive as an application of the theory of the second best. In this case, the market imperfection is that there are not a multitude of firms supplying the market. Rather, we have assumed the extreme opposite case of a monopoly supplier. To make this an international trade story, we simply assume the monopoly happens to be a foreign firm. Consider the market described in Figure 9.4 "Imports from a Foreign Monopoly Firm". Domestic consumer demand is represented by a linear demand curve, D. When demand is linear, it follows that the marginal revenue curve will have twice the slope and will equal demand when the quantity is zero. Let the flat MC line represent a constant marginal cost in production for the foreign monopolist.
