The different approaches to post-adjustment development economics are all examined in this study. The aim is to combine the critical reaction to structural adjustment with the new approaches of a number of schools of thought which seek to go further than the Washington consensus. The first part focuses on recent economic debates influencing current trends in development theory. The second part examines the schools of thought which have sought to renew recent conceptions of development economics by returning to the work of the pioneers. Part three examines recent work in the institutionalist and conventionalist approaches and part four is devoted to the new structuralist and Keynesian approaches. The last part deals with the cultural approach.
