The American statesman Benjamin Franklin (1706–1790) once wrote: “No nation was ever ruined by trade.” Many economists would express their attitudes toward international trade in an even more positive manner. The evidence that international trade confers overall benefits on economies is pretty strong. Trade has accompanied economic growth in the United States and around the world. Many of the national economies that have shown the most rapid growth in the last few decades—for example, Japan, South Korea, China, and India—have done so by dramatically orienting their economies toward international trade. There is no modern example of a country that has shut itself off from world trade and yet prospered. To understand the benefits of trade, or why we trade in the first place, we need to understand the concepts of comparative and absolute advantage.

This topic is considered optional as it would primarily be part of a principles of microeconomics course. If microeconomics is a prerequisite for macroeconomics, this topic can either be skipped entirely, or could be reviewed briefly. In some macroeconomics principles courses, this may need to be presented as new information. Learning objectives of particular interest for a macro course are 1, 2, 7, and 8. Please note that some of the learning objectives contained in this section may overlap with the International Trade unit.

The Principles of Microeconomics course was developed through the Ohio Department of Higher Education OER Innovation Grant.

In this topic, students will be introduced to the elements of international trade. They’ll learn about the gains from trade and how they arise. They’ll learn the difference between absolute and comparative advantage and why comparative advantage is the key to profitable trade. They’ll also be exposed to the types of trade restrictions imposed by governments and the usual justifications for those restrictions.            

This topic introduces key concepts that form the foundation of much of microeconomic analysis. The material ranges from a discussion of model-building as a way to simplify complex relationships among economic variables to definitions and descriptions of key concepts such as scarcity, efficiency and inefficiency, opportunity cost, comparative advantage and the gains from trade.
