The concept and characteristics of structuralism have been found in the world of economics as well. The concept of structuralist economics emphasizes the importance of structural features while doing various economic analyses. Early structuralism models took into account both external and internal disequilibria in productive structures and how they affected the different dependent relationships between the developed world and the developing countries. This work was first started by the director of the ECLA or the Economic Commission for Latin America, Raul Prebish along with Celso Furtado, a Brazilian economist. They believed that distorted development and economic inequality were all a part of the structural features of the global economic system exchange.
