MENDEZ DE HOYOS, Irma. Pre-electoral Coalitions and Partisan Competition in Mexico at the Federal and Local Levels (1994-2011). Polít. gob [online]. 2012, vol.19, n.2, pp.147-198. ISSN 1665-2037.

Pre-electoral coalitions in Mexico constitute one of tendencies of party competition in federal and local elections. Their frequency, composition and level of success are examined and it pretends to show that relevant institutional and political factors are associated to the tendency of growing number of pre electoral coalitions. Findings show that electoral rules that establish costs and benefits, as well as electoral competitiveness are positively related to building coalitions. In addition, and despite opposite perception, ideological compatibility is also important in the process of building coalitions. The evidence that supports these findings consists on the analysis of six federal deputies elections and three presidential elections between 1994 and 2009; and 96 governor elections in 32 states between 1994 and 2011.

Palabras llave : coalitions; parties; local elections; electoral regulations; competitiveness and ideological distance.
