In economics, the Prebisch–Singer hypothesis (also called the Prebisch–Singer thesis) argues that the price of primary commodities declines relative to the price of manufactured goods over the long term, which causes the terms of trade of primary-product-based economies to deteriorate. As of 2013, recent statistical studies have given support for the idea. The idea was developed by Raúl Prebisch and Hans Singer in the late 1940s; since that time, it has served as a major pillar of dependency theory and policies such as import substitution industrialization (ISI).

👉 Prebisch–Singer hypothesis in the context of Raúl Prebisch
Raúl Prebisch (April 17, 1901 – April 29, 1986) was an Argentine economist known for his contributions to structuralist economics such as the Prebisch–Singer hypothesis, which formed the basis of economic dependency theory. He became the executive director of the Economic Commission for Latin America (ECLA or CEPAL) in 1950. In 1950, he also released the very influential study The Economic Development of Latin America and its Principal Problems.
