The theorem can be stated in quite simple terms, but its consequences
are not at all simple: As trade expands, owners of abundant factors of
production benefit, and owners of scarce factors of production are
harmed. Here, "benefit" means their real income increases, while
"harmed" means their real income decreases.
Remember, trade can expand for two main reasons. First technological innovations can reduce the cost of transportation, making it first possible, then cheaper, to send goods long distances. For example, political scientist Ronald Rogowski, in his great book Commerce and Coalitions shows how the introduction of the steamboat made it possible to export North American wheat to Western Europe, displacing wheat from Eastern Europe. Second, policy changes like the North American Free Trade Agreement (NAFTA) or the trade agreements embodying the World Trade Organization (WTO) reduce or eliminate costly barriers to trade and lead to its expansion.
The grain example helps show why trade creates winners and losers. The Midwest U.S. and Canadian Prairie provinces are a gigantic breadbasket made possible by low population density, which implies abundant land and scarce labor. Expanding trade gave these farmers new markets and higher incomes. In much more densely populated Europe, the reverse is true: labor is abundant and land is scarce. As a result, expanding trade in grains meant more import competition and lower income for European farmers..
Fast forward to today and we can ask what U.S. factor endowments are currently. As a rich country internationally, the United States is necessarily a capital abundant country. As a comparatively low population density country, it is land abundant but labor scarce. The answer is to our initial question is then quite clear: expanding trade is harmful to U.S. workers because imports of labor-intensive products and services from abroad create competition for American workers, reducing their real wages. As I have discussed before, U.S. real wages have remained below their peak for 39 straight years, just as the Stolper-Samuelson Theorem would predict.
