Toward a Comparative Institutional Analysis is a monumental achievement offering an ambitious attempt to develop a unified theory of institutions, of the mechanisms of their reproduction over time and of the drivers of their change. The enterprise broadly belongs to the "neoinstitutionalist" perspective in that it searches for microformulations of the very existence and self-reproduction of institutions grounded on the interests and behaviors of self-seeking agents. However, it takes on board insights from diverse perspectives, including "stronger" forms of institutionalism from sociology and political science as well as anthropology.
