Who actually gains when an economy opens its borders to international trade?

Lecture 13: Walrasian Equilibrium and Trade · 59:41 · Video: MIT OpenCourseWare · Watch at the source

In short: This lecture examines the distributional consequences of trade liberalization. It investigates whether capital owners or wage laborers benefit most from open markets and explores the economic implications of restricting immigration while maintaining the free movement of goods.

Professor Robert Townsend explores the mechanics of Walrasian equilibrium within the context of international trade. The analysis focuses on identifying the winners and losers in an economy transitioning toward global integration, specifically comparing the outcomes for those who own capital versus those who rely on wage labor.

The lecture also addresses the theoretical impact of immigration policies. It asks whether building a wall to prohibit the movement of people remains effective when goods are allowed to flow freely across borders, challenging assumptions about how trade and migration interact in a market economy.
