Democracies delegate substantial decision power to politicians. Using a model in which an incumbent can design, examine and implement public policies, we show that examination takes place in spite of, rather than thanks to, elections. Elections are needed as a carrot and a stick to motivate...

This study explores the relationship between social media and democracy in a cross- section of over 125 countries around the world. We find the evidence of a strong, positive correlation between Facebook penetration (a proxy for social media) and democracy. We further show that the correlation...

In a game-theoretical approach of probabilistic voting, we introduce biased beliefs among voters and retrospective voting. In order to micro-found biased beliefs we introduce the psychological concept of mental models. We put into perspective the claim that biased beliefs lead to bad policy...

Social media have become a main source of information for many voters. Political interest groups on social media platforms have the ability to (i) microtarget news based on individual-level voter data and (ii) obfuscate their identities, which can be exploited to spread disinformation. Two...

In "The Myth of the Rational Voter" Brian Caplan shows that voters entertain systematically biased beliefs on a number of essential issues of economic policy and concludes that this leads democracies to choose bad policies. We introduce the psychological concept of mental models to address...

This paper contributes to the literature by carrying out the first econometric investigation into the role of television in the formation of political consensus in Italy. Based on probit and instrumental variables estimates, we find trust in television to be the most significant predictor of...
