Chapter 7 Trade Policy Effects with Perfectly Competitive Markets
Governments have long intervened in international trade by collecting taxes, or tariffs, on imported goods. Tariffs have a long history since they are one of the easiest ways for governments to collect revenue. However, tariffs have a number of other effects besides generating government revenue; they also affect the success of business and the well-being of consumers. And because tariffs affect the volume of trade between countries, they also affect businesses and consumers abroad.
This chapter examines, in detail, the effects of a tariff. However, it also examines the impacts of the many other types of trade policies that governments have applied historically, including import quotas, export quotas, export taxes, and export subsidies.
The effects are considered under one set of standard assumptions—namely, in the case when markets are perfectly competitive.
