This study, based on the author's doctoral dissertation at UCLA, examines Yugoslav economic policy from 1918 to 1929, how it was made, and how it was affected by political developments of the time. It studies the activities of Yugoslavia's regional political and business elites, political groups, and corporations, their reactions to Yugoslav economic policy and their efforts to influence it. The study contains a detailed analysis of party politics and the manner in which the political process affected economic policy. The study uncovers and explains relationships between state, elite, class, national-confessional groups, and territorial regions in the determination of social and economic policy in the Kingdom of Serbs, Croats, and Slovenes, later renamed Yugoslavia, and the relationship between these groups and the Yugoslav state.
