How does "Régulation" theory analyze institutions

Within "régulation" approach institutional forms are the specific expression of one or several basic social relations. They shape the short run process of economic adjustment (the "regulation" mode) as well as the growth regime. Long term transformations of capitalism are the main focus of this theory that has developed various tools in order ,to understand the factors that shape a steady growth, the nature of emerging disequilibria, the key role of social conflicts and political processes in the emergence of alternative "institutionalized compromises". The hypothesis of institutional hierarchy or complementarity helps in understanding the evolution of institutions and the coexistence of various brands of capitalism. The analysis concludes about the need for clear definitions of the basic notions of an institutional political economy and the far reaching and quite ambitious objectives of a general theory of institutions.
