How Trade Liberalization Affects Social Stratification in Developing Countries
Quick fact
Contrary to simple models, trade liberalization in many developing countries has not reduced inequality as predicted; in fact, it often increases the wage gap between skilled and unskilled workers.

Understanding How Trade Liberalization Affects Social Stratification in Developing Countries
Trade liberalization is like removing walls between the domestic economy and the global market. When a developing country opens up, it starts exporting goods it can produce cheaply (often labor-intensive products) and importing goods it produces inefficiently (often capital-intensive goods). This shifts production and demand for workers. In theory, this should increase demand for the abundant factor (unskilled labor) and raise its wages, reducing inequality. But the reality is more complex because most developing countries have a surplus of unskilled labor, and the exported products might require some skills. Also, technology plays a huge role: even in export industries, firms adopt advanced technologies that favor skilled workers. So, the actual effect depends on the country's specific needs, the skills of its workers, and how quickly the economy adapts.
A deeper explanation
The effect of trade liberalization on social stratification is best explained by the Stolper-Samuelson theorem, which predicts that trade benefits the owners of the abundant factor (e.g., unskilled labor) and hurts the owners of the scarce factor (e.g., skilled labor). In a simple two-factor model, this would reduce inequality. However, the real world deviates because of several mechanisms: 1) In many developing countries, the abundant factor is not simply 'unskilled labor' but a vast pool of low-skilled workers in the informal sector, and the export boom may concentrate in sectors that still require a baseline of education. 2) Trade liberalization often coincides with technological change that complements skilled labor, so even as trade expands, the demand for skills rises faster than the supply, widening the wage gap. 3) Import competition can destroy jobs in protected industries, leading to a drop in wages and increasing stratification in the short run. 4) The ability of workers to move between sectors is limited by geography, skills, and social barriers, so the gains from trade are not evenly distributed. Thus, the net effect on social stratification is not a simple one-way street; it is mediated by the structure of the labor market, education levels, and government policies.
