Institutionalization and Peronism - The concept, the case and the case for unpacking the concept

The concept of institutionalization is widely employed but often poorly defined in the literature on political parties. This paper argues that 'institutionalization' as it is frequently used encompasses a diverse set of meanings that are better thought of as conceptually distinct. The paper examines two phenomena that have been widely associated with institutionalization: 'value infusion' and 'behavioral routinization'. It uses the case of Peronism in Argentina, which is infused with value but poorly routinized, to demonstrate that these phenomena can vary independently. The paper argues that the failure to make these conceptual distinctions may pose serious problems for causal analysis. As an example, it shows how different conceptions of institutionalization lead to opposing arguments about the relation between institutionalization and the capacity of parties to adapt to changing electoral and policy environments. The paper then examines the distinction between formal and informal routinization with respect to political parties, arguing that many studies of political parties fail to incorporate informally routinized behavior patterns into their conceptions of institutionalization.
