Core, Periphery, and Semi-Periphery

In global economics, the terms "core," "periphery," and "semi-periphery" describe different roles countries play in the world economy. Core countries are highly developed nations with strong industries, advanced technology, and economic power—like the United States or Germany. Periphery countries are less developed, often relying on exporting raw materials, and have weaker economies—such as some African or Latin American countries. Semi-periphery countries fall in between; they have industrialized economies but are not as powerful—examples include Brazil or India. This model explains how economic benefits and dependencies are distributed unevenly across the world.
