According to the theory of sectoral clashes and coalitions, the sectoral element plays a unique role in affecting, on the one hand, the interrelationships between the economic processes of income creation, distribution, and allocation and, on the other hand, the interrelationships between economic, social, political, and institutional processes that make for change and progress. The objective of this essay is to extend the previous formulation of the theory of sectoral clashes and coalitions along two lines: first, by presenting statistical information from all of Latin America which prima facie supports the theory's basic premises; second, by defining and expanding these premises and the basic framework in an effort to obtain a clearer vision of the theory and its links to economic, political, and social reality. Although most criticisms of the theory find a specific answer and most of the suggestions for improvement are followed, this article is more than a rebuttal. In response to the urgent need for its further development, cited by all commentators and those who have applied and tested the theory in Argentina, Bolivia, Chile, Cuba, Mexico, and Peru, this essay seeks to open new ground and explore new dimensions.
