Power groups,interests and interest groups in consolidated and transitional democracies: comparing Uruguay and Costa Rica with Paraguay and Haiti

Drawing on a representative sample of four countries, this article compares two related aspects of interest group activity across Latin America. First, it identifies the elements that determine the level of interest group system development and types of group activity across the region; and second it provides insights into the relationship of the level of institutionalization of a group system to the extent of the consolidation of democracy. The representative sample is composed of Uruguay and Costa Rica in comparison with Paraguay and Haiti. These are four countries with small populations that cover the spectrum of levels of socioeconomic and political development across Latin America, from Uruguay, one of the most developed, to Haiti one of the least developed. The article argues that across a spectrum of group development in Latin America, advanced systems have more or less integrated characteristics, whereas less developed ones manifest a dual or bifurcated group activity.
