In this paper we study the relationship between inequality and social instability. While the argument that inequality can be damaging for the cohesion of a society is old, the empirical evidence is mixed. We use a novel approach to isolate the causal relationship running from inequality to...

We study the relationship between inequality and social instability. While the argument that inequality can be damaging for the cohesion of a society is well established, the empirical evidence is mixed. We use a novel approach to isolate the causal relationship running from inequality to social...

This paper examines determinants of revolutionary behaviour. We study the role of freedom of communication, repression of opposition and the government's selfishness. Combining econometric analysis of survey data with a laboratory experiment, we analyse how these factors affect preferences for...

In a social network in which friendly and rival bilateral links can be formed, how do alliances between decision-makers form, and what determines whether a conflict will arise? We study a network formation game between ex-ante symmetric players in the laboratory to examine the dynamics of...

We study how conflict in contest games is influenced by rival parties being groups and by group members being able to punish each other. Our motivation stems from the analysis of socio-political conflict. The theoretical prediction is that conflict expenditures are independent of group size and...

We use an experimental lottery choice task and public goods game to examine if responsibility for the financial welfare of others affects decisionmaking behaviour in two different types of decision environments. We find no evidence that responsibility affects individual risk preferences....

In this paper we examine voluntary contributions to a public good when the timing of contributions is endogenously determined by contributors, focusing on the simple quasi-linear setting with two players (Varian, 1994). We show that the move order that is predicted to emerge is sensitive to how...

This paper investigates the efficacy of a punishment mechanism in promoting cooperative behaviour in a public goods game when enforcement of punishment is uncertain. Experimental studies have found that a sanctioning system can induce individuals to adopt behaviour deemed as socially acceptable....

We report an experiment comparing sequential and simultaneous contributions to a public good in a quasi-linear two-person setting. In one parameterization we find that overall provision is lower under sequential than simultaneous contributions, as predicted, but the distribution of contributions...

We experimentally investigate cooperation in privileged groups which according to Olson (1965) are groups in which at least one member has an incentive to supply a positive amount of the public good. More specifically, we analyze group member heterogeneity with respect to two dimensions:...
