Dear Felix,
I think that you may be interested in reading the so called Prebisch
manifesto, that is: R. Prebisch, "The Economic Development of Latin
America and its Principal Problems", UN, 1950 (though actually
manuscripted and delivered in 1949).
Should you need further references on Prebisch, you can see Revista
CEPAL special issue on Prebisch's thought (2000).
Regards,
Andres Lazzarini
