Participatory Democracy is a process of collective decision making that combines elements from both Direct and Representative Democracy: Citizens have the ultimate power to decide on policy and politicians assume the role of policy implementation. The aim of this paper is to understand how...

We analyze experimentally two sender-receiver games with conflictive preferences. In the first game, the sender can choose to tell the truth, to lie, or to remain silent. The latter strategy is costly and similar to an outside option. If sent, the receiver can either trust or distrust the...

In this paper we explore the role of conflict as an informational device by means of a simple bargaining model with one-sided incomplete information: Limited conflicts reveal information about the outcome of the all-out conflict (that ends the game) because the outcomes of both types of...

This paper analyzes coalition formation in a model of contests with linear costs. Agents first form groups and then compete by investing resources. Coalitions fight for prizes that are assumed to be subject to rivalry, so their value is non-increasing in the size of the group. This formulation...

This paper explores the role of conflict as a bargaining tool. It first presents a simple bargaining model with one-sided incomplete information. Parties can choose the scope of the confrontation they may want to engage in: A limited conflict that only introduces delay, or an absolute conflict...

A recent experimental study of Cai and Wang (2003) on strategic information transmission games reveals that subjects tend to transmit more information than predicted by the standard equilibrium analysis. To evidence that this overcommunication phenomenon can be explained in some situations in...

We analyse risk-taking behaviour of banks in the context of a model based on spatial competition. Banks mobilise deposits by offering deposit rates. We show that when the market concentration is low, banks invest in the gambling asset. On the other hand, for sufficiently high levels of market...

We propose an elementary theory of wars fought by fully rational contenders. Two parties play a Markov game that combines stages of bargaining with stages where one side has the ability to impose surrender on the other. Under uncertainty and incomplete information, in the unique equilibrium of...

We study how the possibility of a conflict between natives and immigrants shapes income redistribution in democracies. Conflict erupts when immigrants are given less than what they could obtain by resorting to confrontation. That in turn can make natives vote for lower tax rates and lower public...

Recent research has analyzed how individual characteristics, like the exposure to different hormones and symmetry, affect decision-making and strategic behaviour. The present article investigates the effect of symmetry, of exposure to testosterone (T) in utero and during puberty and of current T...
