Debates: Voting and Expenditure Responses to Political Communication

Candidate debates have a rich history and remain integral to contemporary campaign strategy. There is, however, no evidence that they affect the behavior of voters or elected politicians. The scarcity of political information in the developing world offers an attractive testing ground. Using experimental variation in Sierra Leone, we find that public debate screenings build political knowledge that changes the way people vote, which induces a campaign expenditure response and fosters accountability pressure over the spending of elected officials.  We parse the effects of information conveyed about policy versus charisma, and find that both are needed.  The results support a simple model of how information provision can enhance competition, and thereby reduce rent extraction, even where regional party strongholds create lopsided races.
