MARTI I PUIG, Salvador. The Reasons for the Presence and Success of Ethnic Parties in Latin America: The Cases of Bolivia, Ecuador, Guatemala, Mexico, Nicaragua y Peru (1990-2005). Rev. Mex. Sociol [online]. 2008, vol.70, n.4, pp.675-724. ISSN 2594-0651.

The text examines if there is a causal link between the presence of ethnic parties in six Latin American countries and the "favorable conditions" indicated by the literature on collective action. The author undertakes a multi-causal, qualitative analysis oriented towards cases and variables wich uses Boolean logic to systematically simplyfy complex data structures. This is used to identify the causal patterns why ethnic parties have been successful in Bolivia, Ecuador and Nicaragua, but not in Guatemala, Mexico and Peru.
