Suspiciously timed trade disputes

This paper shows that electoral incentives crucially affect the initiation of trade disputes. Focusing on WTO disputes filed by the United States during the 1995-2014 period, we find that U.S. presidents are more likely to initiate a dispute in the year preceding their re-election. Moreover, U.S. trade disputes are more likely to involve industries that are important in swing states. To explain these regularities, we develop a theoretical model in which re-election motives can lead an incumbent politician to file trade disputes to appeal to voters motivated by reciprocity.
