7.12 Import Quota: Large Country Welfare<br />

Effects<br />

LEARNING OBJECTIVES<br />

1. Use a partial equilibrium diagram to identify the welfare effects of an import quota on<br />

producer <strong>and</strong> consumer groups <strong>and</strong> the government in the importing <strong>and</strong> exporting<br />

countries.<br />

2. Calculate the national <strong>and</strong> world welfare effects of an import quota.<br />

Suppose for simplicity that there are only two trading countries: one importing country <strong>and</strong> one exporting<br />

country. The supply <strong>and</strong> dem<strong>and</strong> curves for the two countries are shown in Figure 7.25 "Welfare Effects of a<br />

Quota: Large Country Case". PFT is the free trade equilibrium price. At that price, the excess dem<strong>and</strong> by the<br />

importing country equals the excess supply by the exporter.<br />

Figure 7.25 Welfare Effects of a Quota: Large Country Case<br />

The free trade quantity of imports <strong>and</strong> exports is shown as the blue line segment on each country’s graph<br />

(the horizontal distance between the supply <strong>and</strong> dem<strong>and</strong> curves at the free trade price). Suppose the large<br />

importing country implements a binding quota set equal to the length of the red line segment (the<br />

horizontal distance between the supply <strong>and</strong> dem<strong>and</strong> curves at either the higher import price or the lower<br />

export price). When a new equilibrium is reached, the price in the importing country will rise until import<br />
