Trade has income distribution effects. For example, suppose that because of a government negotiated reduction in trade barriers, trade between Germany and the Czech Republic increases. Germany sells house paint to the Czech Republic. The Czech Republic sells alarm clocks to Germany. Would you expect this pattern of trade to increase or decrease jobs and wages in the paint industry in Germany? The alarm clock industry in Germany? The paint industry in Czech Republic? The alarm clock industry in Czech Republic? What has to happen for there to be no increase in total unemployment in both countries?

Key Concepts

Trade Liberalization

This concept refers to the reduction or removal of trade barriers such as tariffs, quotas, and regulations, which allows goods and services to flow more freely between countries. As trade barriers are reduced, industries that are competitive on international markets may expand, while less competitive industries may contract, leading to shifts in employment and wage structures.

Income Distribution Effects

Trade can have differing impacts across various sectors, resulting in gains for some groups and losses for others. Changes in the pattern of trade may benefit export sectors through increased demand while harming import-competing sectors, thereby affecting wages and job opportunities within specific industries and influencing the overall distribution of income within a country.

Export and Import Competitive Industries

Industries that are competitive in export markets are likely to experience growth, higher wages, and increased employment because of greater demand from abroad. Conversely, industries that face stiff competition from imports are susceptible to reduced demand, lower wages, and job losses. The relative competitiveness of these industries drives the sector-specific outcomes seen in trade.

Stolper-Samuelson Theorem

This theorem explains how trade liberalization affects factor incomes by linking the rise or fall in the price of goods to changes in wages and returns to factors of production. Essentially, it predicts that the factor used intensively in the export sector will benefit from trade, while the factor used intensively in the import-competing sector may suffer, thus contributing to the redistribution of income within the economy.

Factor Mobility

The ease with which labor and capital can shift between sectors is critical in mitigating the negative effects of trade on employment. High factor mobility allows resources to be reallocated from declining industries to expanding ones, ensuring that while some workers may initially lose their jobs, they can transition into sectors that are growing, which is essential for preventing a rise in total unemployment and achieving overall economic adjustment.
