We show that regional heterogeneity of underlying fundamentals (e.g. economic history, geography, social capital) can lead to extreme voting in federations. When the outcome of federal policies – such as transfer schemes, market regulation or migration laws – depends on these fundamentals,...

In this chapter, we review the recent literature on conflict and appropriation. Allowing for the possibility of conflict, which amounts to recognizing the possibility that property rights are not perfectly and costlessly enforced, represents a significant departure from the traditional paradigm...

Rent seeking contest shapes the risk preference of the contestants. It instills in the weaker contestant who has little to lose and much to gain a preference for risk taking, and the weaker the contestant, the stronger the instilled preference for risk taking. On the other hand, it causes the...

A conclave is a voting mechanism in which a committee selects an alternative by voting until a sufficient supermajority is reached. We study experimentally welfare properties of simple three-voter conclaves with privately known preferences over two outcomes and waiting costs. The resulting game...

We study communication in committees selecting one of two alternatives when consensus is required and agents have private information about their preferences. Delaying the decision is costly, so a form of multiplayer war of attrition emerges. Waiting allows voters to express the intensity of...

Experiments evaluate the fit of human behaviour to the Shapley-Shubik power index (SSPI), a formula of voter power. Groups of six subjects with differing votes divide a fixed purse by majority rule in online chat rooms. Earnings proxy for measured power. Chat rooms and processes for selecting...

We study communication in committees selecting one of two alternatives when consensus is required and agents have private information about their preferences. Delaying the decision is costly, so a form of multiplayer war of attrition emerges. Waiting allows voters to express the intensity of...

In this chapter, we assess recent contributions of computational models to the study of politics. We focus primarily on agent-based models developed by economists and political scientists. These models address collective action problems, questions related to institutional design and performance,...

Political competition, party strategy and communication in the era of social media are growing issues. Due to the increasing social media presence of parties and voters alike, direct communication is more important for party competition. This paper aims to improve the methodological approach...

Populist parties have grown rapidly in popularity in most European countries, and are increasingly common in government coalitions. Analyzing 183 populist parties in 33 European countries from 1980 to 2021, we estimate the average effect of being in government on election results. On average, we...
