This paper studies a cheap talk model in which two senders having partial and non-overlapping private information simultaneously communicate with an uninformed receiver. The sensitivity of the receiver’s ideal action to one sender’s private information depends on the other sender’s private information. We show that the senders’information transmissions exhibit strategic complementarity: more in...

We study the recruitment of individuals in the political sector. We propose an equilibrium model of political recruitment by two political parties competing in an election. We show that political parties may deliberately choose to recruit only mediocre politicians, in spite of the fact that they could select better individuals. Furthermore, we show that this phenomenon is more likely to occur i...

We study how norms can solve distributional conflict inside a clan and the efficient coordination of collective action in a conflict with an external enemy. We characterize a fully non-cooperative equilibrium in a finite game in which a self-enforcing norm coordinates the members on efficient collective action and on a peaceful distribution of the returns of collective action.

This note characterizes the ‘inverse plurality rule’, where voters specify only their least preferred alternative. This rule is characterized by a new minimal veto condition (MV) and the four well known conditions that characterize scoring rules; namely, Anonymity (A), Neutrality (N), Reinforcement (RE) and Continuity (C). Our new characterization result is related to the characterizations of a...

In this paper we present a generalization of power indices which includes the preferences of the voters. Using a Multilinear Extension perspective (Owen, 1972a) we measure the probability of the players’ voting ’yes’ for a particular political issue. Further, we randomize the issues and show the influence that the Agenda Setter can have on a player’s power. We demonstrate these results using da...

When politicians are provided with insufficient incentives by the democratic election mechanism, we show that social welfare can be improved by threshold contracts. A threshold incentive contract stipulates a performance level which a politican must reach in order to have the right to stand for reelection. Read my lips would turn into read my contracts. Reelection thresholds can be offered by p...

The purpose of this note is to compute the probability of logrolling for three different probabilistic cultures. The primary finding is that the restriction of preferences to be in accord with the condition of separable preferences creates enough additional structure among voters’ preference rankings to create an increase in the likelihood that a Condorcet winner will exist with both IC and IAC...

We study a model of electoral competition where voters obtain information on candidates’ platforms through campaign advertising, and word-of-mouth communication. We show that when the costs of campaign advertising are low, an increase in word-of-mouth communication among voters causes polarization. In particular, the more voters can exchange political information between each other, the more of...

In this paper we argue that the number of candidates running for public office, their ideological differentiation, and the intensity of campaign competition are all naturally intertwined, and jointly determined in response to the incentives provided by the electoral system. We propose a simple general equilibrium model that integrates these elements in a unitary framework, and provide a compari...

This paper studies the advantages that a coalition of agents in a larger electorate can obtain by forming a voting bloc to pool their votes and cast them all in one direction. We show under which conditions an agent will benefit from the formation of the voting bloc, whether being part of it or stepping out is most advantageous for an individual agent and what are the different optimal internal...
