Abstract

We exploit seating rules in the European Parliament to identify peer effects in legislative voting. Sitting adjacently leads to a 7 percent reduction in the overall likelihood that two Members of the European Parliament (MEPs) from the same party differ in their vote, but peer effects are markedly stronger among women, among MEP pairs from the same country, and in close votes. Using variation in seating across the two venues of the Parliament (Brussels and Strasbourg), we also show that peer effects are persistent: MEPs who have sat together in the past are less likely to disagree even when they are not seated adjacently.
