American sociologist who developed World Systems Theory (Capitalist World Economy) to explain global economic stratification.
A theory that holds that core countries are intimately connected with peripheral and semi-peripheral countries in a world system, and that the core exploits the periphery.
Powerful countries that economically, politically, and culturally control most of the world system.
Weak countries that have been integrated into the world system in a dependent position.
Countries in the middle that benefit from close relationships with core countries in the exploitation of periphery countries.
