Dependency theory, an approach to understanding economic underdevelopment that emphasizes the putative constraints imposed by the global political and economic order. First proposed in the late 1950s by the Argentine economist and statesman Raúl Prebisch, dependency theory gained prominence in the 1960s and ’70s.

According to dependency theory, underdevelopment is mainly caused by the peripheral position of affected countries in the world economy. Typically, underdeveloped countries offer cheap labour and raw materials on the world market. These resources are sold to advanced economies, which have the means to transform them into finished goods. Underdeveloped countries end up purchasing the finished products at high prices, depleting the capital they might otherwise devote to upgrading their own productive capacity. The result is a vicious cycle that perpetuates the division of the world economy between a rich core and a poor periphery.
