Political Trust and American Public Support for Free Trade

Debates over trade liberalization vs. protectionism have becoming increasingly relevant as the world moves through a contentious era of economic globalization. This is particularly true in the United States, where an elite consensus on the merits of free trade has fractured in recent years. While we know a good deal about the economic and cultural determinants of trade opinion, we know little about how attitudes toward government may matter. Here, I address this oversight by examining the relationship between political trust and trade support. I do this with cross-sectional and panel data from the American National Election Studies (ANES) and the National Annenberg Election Surveys (NAES), and a survey experiment fielded through Amazon’s Mechanical Turk (MTurk). Overall, I find that there is a positive and substantively significant relationship between political trust and mass support for free and open “pro-trade” policies. I attribute this to greater citizen confidence that government will pursue trade deals in the national interest and mitigate any perceived risks associated with free trade. These findings help us to better understand the determinants of public opinion toward trade policy and underscore the consequences of political trust.
