DECEPTION AND POLITICAL PARTICIPATION: THEORY AND LABORATORY EVIDENCE

We model two-candidate elections in which (1) voters are uncertain about candidates' attributes; and (2) candidates can inform voters of their attributes by sending advertisements. We compare between political campaigns with truthful advertising and campaigns in which there is a small chance of deceptive advertising. Our model predicts that voters should vote in-line with an advertisement's information. We test our model's predictions using laboratory elections. We find, in the presence of even a small probability that an advertisement is deceptive, voters become substantially more likely to elect a low-quality candidate. We discuss implications of this for existing models of voting decisions. (JEL C92, D72, D82)
