Existing studies of Congressional behavior devote little attention to understanding legislators' trade-related position taking outside the context of roll call votes. Using a new dataset on bill sponsorship that spans fifteen congresses, the author explores the factors that affect a senator's propensity to introduce protectionist trade bills, including state-level manufacturing characteristics, economic cycles and electoral vulnerability. The results provide support for a number of the prominent economic-based explanations for trade policy preferences, including the Heckscher-Ohlin and Ricardo-Viner models, and also draw attention to several additional economic and political influences on policy outcomes. Beyond trade politics, these findings have implications for the expanding body of research on bill sponsorship as well as the literature on the role of Congress in U.S. foreign policy making.Master of Art
