Stefano DellaVigna is the Daniel Koshland, Sr., Distinguished Professor of Economics at the Haas School of Business.
DellaVigna is a prolific researcher in behavioral economics. His studies have explored consumer behavior, investor inattention, persuasion, and the interplay between media and politics.
In 2007, he co-authored a pioneering study that documented Fox News’s substantial impact on voting in national elections. The study examined election data in 9,526 towns that began receiving Fox News between 1996 and 2000. It found that the arrival of Fox in local media markets increased the Republican vote share by as much as .7 percentage points between the 1996 and 2000 elections. Overall, it estimated, Fox had persuaded between 3 and 28 percent of its viewers to vote Republican.
