Political conflict between nations sometimes leads to consumer boycotts. We examine the regional impacts of bilateral boycott activity by investigating the 2019 Korean consumer boycott of travel to Japan. Employing triple- and double-differences designs, we find that the impact of the boycott is large and regionally heterogeneous. Japanese prefectures with high (i.e., 75th percentile) pre-boycott dependency on visitors from Korea suffer bilateral export losses of 56.9 to 60.9 percent and aggregate export losses of 10.5 to 13.3 percent. Prefectures with low (i.e., 25th percentile) Korea dependency experience bilateral losses of 47.8 to 49.7 percent and aggregate losses of 3.3 to 4.2 percent.
