What Lies Beneath: Mediators of Public Support for International Economic Cooperation

Abstract

The current public backlash against several trade agreements has triggered a vivid discourse about the impact of top-down communication of such initiatives on public opinion. Findings from previous work on the impact of issue frames provide distinct expectations about the influence of different types of messages on people’s opinion. However, little is known about the mechanisms underlying the impact of message cues on opinion formation. In this article, we shed light on one potential mechanism that mediates issue framing effects: individuals’ emotional reaction. By means of a survey-embedded experiment conducted in the United States and Germany, we expose respondents to different frames about the benefits and risks of the Transatlantic Trade and Investment Partnership agreement. The results show that frames have a significant effect on public opinion, but frames that emphasize losses seem more persuasive than frames promoting the gains from the Transatlantic Trade and Investment Partnership. Complementing our empirical investigation, with a causal mediation analysis we find that framing effects are indeed mediated by people’s emotional responses to the frames.
