Why preferences and institutions change: A systematic process analysis of credit rating in Germany

Abstract

This article argues that a within-case analysis of the causes and patterns of the institutionalisation of rating in the German financial system offers fresh insights into change in the major socioeconomic institutions of advanced capitalism. Using the method of systematic process analysis, the article explores the expansion of credit rating in the German banking system from three perspectives: historical (power), sociological (diffusion) and behavioural institutionalism (prospect theory). It demonstrates that the proliferation of credit rating resulted from a change of preference on the part of large banks. With Germany as a least likely case for successfully implementing rating, the study's main lesson is that institutional analysis may benefit from incorporating behavioural institutionalism into the analysis of preference change because this cites economic motivations as causes of preference shifts and institutional changes. © 2013 European Consortium for Political Research.
