Mass Attitudes about International Trade Agreements: Positive Messages and the Trans-Pacific Partnership

Abstract From the understanding that the mass public knows little about the benefits of international trade agreements but nonetheless opposes them with opposition representing a problem for domestic ratification, this research note explores if and what messages about the Trans-Pacific Partnership might increase popular support. The experimental results show that providing more background information alone does not increase support, but adding an economic message about how this agreement could lower prices or a security message about how it would help the United States counter China increases support. The economic message also encourages respondents to write a statement to their Senators urging them to vote for ratification. These positive effects appear even within groups that are more opposed, namely less educated citizens and Republicans. Our results address important questions about the formation of trade policy preferences, showing they can be shifted in directions contrary to one's egocentric interests and partisan predispositions.
