Document Summary
Goods and services purchased from other countries are imports; goods and services sold to other countries are exports. Globalization is the phenomenon of growing economic linkages among countries. Hyperglobalization is the phenomenon of extremely high levels of international trade. The ricardian model of international trade analyzes international trade under the assumption that opportunity costs are constant. Autarky is a situation in which a country does not trade with other countries. In fact, the consumption choices of a country reflect both the preferences of its residents and the relative prices the prices of one good in terms of another in international markets. One requirement that the relative price must satisfy is that no country pays a relative price greater than its opportunity cost of obtaining the good in autarky. Economists who study international trade have found three main sources of comparative advantage: international differences in climate, international differences in factor endowments, and international differences in technology.
