Why international trade creates winners and losers based on factor mobility

The specific factors model explains why some workers and industries thrive under global trade while others suffer. By examining why production factors cannot always move freely, we can better understand the real-world impact of imports and exports on wages and regional prosperity.

The specific factors model posits that not all production inputs are mobile. When trade patterns shift, the consequences fall disproportionately on these fixed, immobile factors. Because these resources cannot easily transition to other sectors, they are uniquely vulnerable to the fluctuations of international markets.

For example, in the 1980s, the rise of Japanese car imports into the United States negatively impacted American auto workers in Detroit, who were tied to that specific industry and faced wage cuts or job losses. Conversely, when global demand for French wine rises, owners of French vineyards benefit because their land is a fixed, immobile factor that gains value from the increased export activity.
