We study communication in ambiguous environments. Agents communicate individual decisions sequentially. Based on the signal that an agent receives, she revises her private information. When signals are ambiguous, we show that agents may agree to disagree forever. Although the learning process...

Politicians tend to push the amount of public debt beyond socially desirable levels in order to increase their reelection chances. We develop a model that provides a new explanation for this behavior: office holders undertake debt-financed public projects, but postpone the timing of part of the...

We examine the effects of a novel political institution, which we call Coalition- Preclusion Contracts, on elections, policies, and welfare. Coalition-Preclusion Contracts enable political parties to credibly commit before the elections not to form a coalition after the elections with one or...

Politicians may pander to public opinion and may renounce undertaking beneficial long-term projects. To alleviate this problem, we introduce a triple mechanism involving political information markets, reelection threshold contracts, and democratic elections. An information market is used to...

In this paper, we present a new way to deal with initiatives, i.e. proposals that can be submitted to voting by the citizens of a democracy. We call it “Assessment Voting”. It takes place in two rounds. Before the conclusive voting, a given number of randomly-chosen voters casts its votes....
