Institutionalism (s): Explanatory models and causality
The explanation is assumed as an essential feature of political studies as a special genre of political discourse. Two explanatory models, which have been developed in institutional political studies, are discussed in the article. Deductive-nomological model inherent in rational choice institutionalism meets the requirements of logical positivism to a great extent, but because of its rigidity it has some limitations. Sociological institutionalism uses more flexible categorial scheme as an explanatory model.
