Organized crime uses political violence to influence politics in a wide set of countries. This paper exploits a novel dataset of attacks directed towards Italian local politicians to study how (and why) criminal organizations use violence against them. We test two competing theories to predict...

The possibility of treason by a close associate has been a nightmare of most autocrats throughout history. More competent viziers are better able to discriminate among potential plotters, and this makes them more risky subordinates for the ruler. To avoid this, rulers, especially those which are...

As the performance of long-term projects is not observable in the short run politicians may pander to public opinion. To solve this problem, we propose a triple mechanism involving political information markets, reelection threshold contracts, and democratic elections. An information market is...

This paper takes a mechanism design approach to federalism and assumes that local preferences are the private information of local jurisdictions. Contractual federalism is defined as a strategy-proof contract among the members of the federation supervised by a benevolent but not omniscient...

A committee makes a decision on a project on behalf of the public. Members of the committee agree on the a priori value of the project, and hold additional private information about its consequences. They are experts who care about the value of the project and about being considered well...

We suggest a model of electoral competition between two parties which is extended by a third player : mass media. The classical one-dimensional competition model is changed by introducing an issue-specific sensibility-coefficient and by allowing for non-voting. The winner is selected by majority...

We study experimentally the effectiveness of communication in common value committees exhibiting publicly known heterogeneous biases. We test models assuming respectively self-interested and strategic-, joint payoff-maximizing- and cognitively heterogeneous agents. These predict varying degrees...

The paper investigates strategic campaigning in a model of redistributive politics in a society with many groups and two parties. Campaigns are informative, and parties can target campaigns to different groups. Voters are uncertain about whether parties fabor special groups. The parties will...

We model an election between two Downsian mainstream candidates and a third inflexible politician. There is uncertainty about the state of the world. Candidates receive signals on the state and propose a policy to implement. There are two classes of voters: ideological, who are biased towards...

This paper studies a contest in which players with unobservable types may form an alliance in a pre-stage of the game to join their forces and compete for a prize. We characterize the pure strategy equilibria of this game of incomplete information. We show that if the formation of an alliance is...
