market decreases producer surplus in the industry. The price decline also induces a decrease in output, a decrease in employment, and a decrease in profit, payments, or both to fixed costs. Import quota effects on the quota rents. There are no quota rent effects on the exporting country as a result of the importer’s quota unless the importing government gives away the quota rights to foreigners. Only in this case would the rents accrue to someone in the exporting country. Import quota effects on the exporting country. The aggregate welfare effect for the country is found by summing the gains and losses to consumers and producers. The net effect consists of three components: a negative terms of trade effect (g), a negative consumption distortion (f), and a negative production distortion (h). Since all three components are negative, the importer’s tariff must result in a reduction in national welfare for the exporting country. However, it is important to note that a redistribution of income occurs—that is, some groups gain while others lose. In this case, the sum of the losses exceeds the sum of the gains. Import quota effects on world welfare. The effect on world welfare is found by summing the national welfare effects on the importing and exporting countries. By noting that the terms of trade gain to the importer is equal to the terms of trade loss to the exporter, the world welfare effect reduces to four components: the importer’s negative production distortion (B), the importer’s negative consumption distortion (D), the exporter’s negative consumption distortion (f), and the exporter’s negative production distortion (h). Since each of these is negative, the world welfare effect of the import quota is negative. The sum of the losses in the world exceeds the sum of the gains. In other words, we can say that an import quota results in a reduction in world production and consumption efficiency. KEY TAKEAWAYS An import quota lowers consumer surplus in the import market and raises it in the export country market. An import quota raises producer surplus in the import market and lowers it in the export country market. National welfare may rise or fall when a large country implements an import quota. National welfare in the exporting country falls when an importing country implements an import quota. An import quota of any size will reduce world production and consumption efficiency and thus cause world welfare to fall. Saylor URL: http://www.saylor.org/books Saylor.org 355
EXERCISES 1. Consider the following trade policy action (applied by the domestic country) listed at the top of the second column in the table below. In the empty boxes, use the following notation to indicate the effect of the policy on the variables listed in the first column: + the variable increases − the variable decreases 0 the variable does not change A the variable change is ambiguous (i.e., it may rise, it may fall) Use a partial equilibrium model to determine the answers, and assume that the shapes of the supply and demand curves are “normal.” Assume that the policy does not begin with, or result in, prohibitive trade policies. Also assume that the policy does not correct for market imperfections or distortions. For example, an import quota applied by a large country will cause an increase in the domestic price of the import good; therefore a + is placed in the first box of the table.
