Book excerpt: Upon its publication in 1989, this was the first systematic and comprehensive analysis of the Latin American School of Development and an invaluable guide to the major Third World contribution to development theory. The four major strands in the work of Latin American Theorists are: structuralism, internal colonialism, marginality and dependency. Exploring all four in detail, and the interconnections between them, Cristobal Kay highlights the developed world’s over-reliance on, and partial knowledge of, dependency theory in its approach to development issues, and analyses the first major challenges to neo-classical and modernisation theories from the Third World.
