Preferencias estratégicas de los partidos políticos y gobiernos de coalición autonómicos

Abstract

Political scientists classifies the types of government in the most common democracies regimen types, parliamentarism, according to the variable «number of parties», with which, they appear to us two types: single-party government and coalition government. Theories which they explain them faces several disadvantages. The party government has his explanation in the rule of the majority that constitutes it and if that criterion does not serve, they are used other variables, such as «the institutional conditions» and «opportunity». When the government is a coalition, different types from preferences have seted out to calculate the result and it knows that to predict an only result is necessary that the used criteria are applied by the political actors in the same lexicographical order. Even so, the coalitions that do not reachthe absolute majority not consider, although yes much attention to the minority governments and theeffects of the institutions and the democratic process has been lent last to understand its formation. In order to avoid these difficulties and to unify the results we propose the classification of the parliamentary types of government according to two variables: the number of parties and the type of majority. Subsequently, one resorts to explain the six types of resulting governments based on the combination of the strategic preferences of the parties and the institutional rules of decision, with exemplifications of some cases of the Spanish autonomic governments.
