Informed voters are believed to be necessary for the well-functioning of elections. However, the puzzle is raised: Why are voters and politicians becoming more polarized despite the increased availability of information? We consider an election with policy-motivated candidates and partially...

Majority voting is considered an efficient information aggregation mechanism in committee decision-making. We examine if this holds in environments where voters first need to acquire information from sources of varied quality and cost. In such environments, efficiency may depend on free-riding...

We investigate the potential of transparency to influence committee decision-making. We present a model in which career concerned committee members receive private information of different type-dependent accuracy, deliberate and vote. We study three levels of transparency under which career...

We examine the incentives to self-select into politics and how they depend on the transparency of the entry process. To this end, we set up a two-stage political competition model and test its key mechanisms in the lab. At the entry stage, potential candidates compete in a contest to become...

This paper proposes the following mechanism whereby polarization of beliefs could eliminate political gridlock instead of intensifying disagreement: the expectation of political payoffs from being proven correct by a policy failure could drive decision makers who do not believe in the new policy...

Despite controversial debates about the social acceptability of its nationalist program, the rightwing populist AfD has recently entered all state parliaments as well as the federal parliament in Germany. Although professed AfD voters faced a likely risk of social stigmatization, electoral...

Can campaign communications credibly transmit information about candidates' policy intentions? To answer this question, I develop and analyze a game-theoretic model of campaign communication in a two-candidate majority rule election with multidimensional policies. Candidate and voter preferences...

In this article I analyze a model of interest group influence on legislative voting through information transmission. The model shows how interest groups may manipulate voting coalitions to their advantage by crafting different messages to target different winning coalitions. Furthermore, if...
