The Argentinean economist Raúl Prebisch’s (1901-1986) ideas were always gone back to the action. Difficulties facing concrete problems made him a pragmatic man. Thus, his theories about import substitution, core-periphery system and the creation of a common Latin-American market, were embodied in a great purpose of influencing the reality. The only exception was the "Theory of Transformation", which was built in the last decade of this life. There, Prebisch moves off practical matters and speculates about the creation of a new economic system, through a synthesis of socialism and liberalism.
