Although new institutionalism has long been criticised for presenting overly static accounts of social reality, that critique is becoming increasingly unwarranted. In recent years, historical, ideational and rational choice institutionalists have produced a rich body of literature on mechanisms and processes of institutional change. This article reviews this emerging literature and concludes that the most promising avenue for future research is to further explore the potential for combining insights from the three subtypes of institutionalism. In the hopes of encouraging future studies of institutional change to engage more explicitly in theoretical integration, this article proposes a sequential approach to combining insights from different traditions and providing comprehensive accounts of exogenous and endogenous processes of institutional change.
