Some people have a concern for a fair distribution of incomes while others do not. Does such a concern matter for majority voting on redistribution? Fairness preferences are relevant for redistribution outcomes only if fair-minded voters are pivotal. Pivotality, in turn, depends on the structure...

Intelligence about transnational terrorist threats is generally gathered by national agencies. I set up and analyze a game theoretic model to study the implications of national intelligence gathering for the provision of domestic (defensive) counterterrorism when two countries are facing a...

This is an experimental study of a three-player power-to-take game where a proposer is matched with two responders. We compare a treatment in which subjects are anonymous to each other (strangers) with one in which responders know each other from outside the lab (friends). We focus on the...

This paper investigates how social composition affects social conflict and economic development when property rights are unenforceable. Groups follow Markovian strategies for consumption and investment and may also spend effort in an resource appropriation contest. It is shown that conflict...

We investigate how social composition affects competitive and cooperative behavior in a linear growth model without a priori secure property rights. If a society is homogenous or highly fractionalized it is in the self-interest of people to cooperate. The first best allocation is enforced...

We analyze development trajectories of early civilizations where population size and technology are endogenous, and derive conditions under which such societies optimally “switch” from anarchy to hierarchy – when it is optimal to elect and support a ruler. The ruler provides an efficient...

This paper experimentally explores how the enforcement of cooperative behavior in a social dilemma is facilitated through institutional as well as emotional mechanisms. Recent studies emphasize the importance of anger and its role in motivating individuals to punish free riders. However, we find...

In this paper we contribute to the study of how democracy works when politicians are better informed than the electorate about conditions relevant for policy choice. We do so by setting up and analyzing a game theoretic model of electoral competition. An important feature of the model is that...

This paper considers generalized Lorenz-maximal solutions in the core of a convex TU-game and demonsrtates that such solutions satisfy coalitional monotonicity and population monotonicity.
