Quick Summary

World-systems theory, developed by Immanuel Wallerstein, posits that the global economy functions as a single, expanding capitalist system since the 17th century. This theory suggests that economically active core countries enrich themselves at the expense of peripheral regions. Unlike modernization theory, which anticipates eventual development for all nations, world-systems theory views "underdevelopment" as a direct result of exploitation by industrialized nations.12

The theory categorizes countries into "core," "semi-peripheral," and "peripheral" based on their position within this global economic structure. While influential, world-systems theory has faced criticism for being Eurocentric and its evidence has been questioned. It emphasizes the interconnectedness of nations through trade, the exchange of ideas, and the spread of diseases, highlighting how global economic developments increasingly subordinate individual nation-states.12
