This paper studies information diffusion in social media and the role of bots in shaping public opinions. Using Twitter data on the 2016 E.U. Referendum (“Brexit”) and the 2016 U.S. Presidential Election, we find that diffusion of information on Twitter is largely complete within 1-2 hours....

We find that Republican candidates lost support in the 2018 congressional election in counties more exposed to trade retaliation, but saw no commensurate electoral gains from US tariff protection. The electoral losses were driven by retaliatory tariffs on agricultural products, and were only...

Inversions—in which the popular vote winner loses the election—have occurred in four US presidential races. We show that rather than being statistical flukes, inversions have been ex ante likely since the early 1800s. In elections yielding a popular vote margin within one point (one-eighth...

Voters punish incumbent Presidential candidates for contractions in the local (county-level) supply of mortgage credit during market-wide contractions of credit, but they do not reward them for expansions in mortgage credit supply in boom times. Our primary focus is the Presidential election of...

We combine a new dataset of weekly Catholic church donations with a new dataset of presidential-election campaign stops to explore the impact of stops on donations. We find that stops increase donations, with a campaign stop generating 2 percent more donations in the following week. Our results...

The 1896 presidential election between William Jennings Bryan and William McKinley has gained new salience in the wake of the 2016 contest. We provide the first systematic analysis of voting patterns in 1896, combining county-level returns with economic, financial, demographic and climatological...

This paper studies how international trade influences U.S. presidential elections. We expect the positive employment effects of expanding exports to increase support for the incumbent's party, and job insecurity from import competition to diminish such support. Our national-level models show for...

To understand the extent to which partisan majorities in Congress influence economic policy, we compare financial market responses in recent midterm elections to Presidential elections. We use prediction markets tracking election outcomes as a means of precisely timing and calibrating the...
