Abstract:
The paper discusses the League of Nations's project to produce consensus in the interpretation of aggregate economic fluctuations in the 1930s. G. Haberler started working in 1934 at the League of Nations headquarters in Geneva on a broad enquiry that should lead to a synthesis of the several conflicting explanations of the causes of the business cycles, which culminated with the publication of his classic book in 1937. The paper makes use of archival material hitherto unexplored - such as correspondence and verbatim records of conferences - to show how the discussions with economists at the time were incorporated into Haberler's final report, and to interpret in what extent the attempt to reach a consensus was successful.
