This paper aims to explain the rise and fall of communism by exploring the interplay between economic incentives and social preferences in different economic systems. We introduce inequality-averse and inefficiency-averse agents responding to economic incentives and transmitting their ideology...

We analyze stability of self-enforcing climate agreements based on a data set generated by the CLIMNEG world simulation model (CWSM), version 1.2. We consider two new aspects which appear important in actual treaty-making. First, we consider a sequential coalition formation process where players...

We consider a simple dynamic model of environmental taxation that exhibits time inconsistency. There are two categories of firms, Believers, who take the tax announcements made by the Regulator to face value, and Non-Believers, who perfectly anticipate the Regulator's decisions, albeit at a...

Are natural resources a source of conflict or stability? Empirical studies demonstrate that rents from natural resources, and in particular oil, are an important source of civil war. Allegedly, resource rents attract rent seekers, which destabilize society. However, there is a large literature...

We build a simple model of legal dualism in which a pro-poor legal reform, under certain conditions, causes the conflicting custom to go some way toward producing the change intended by the legislator. It then acts as an "outside anchor" that exerts a "magnet effect" on the custom. We illustrate...

We consider a situation where groups negotiate over the allocation of a surplus (which is used to fund group specific goods). Each group is composed of agents who have differing valuations for public goods. Members choose a representative to take decisions on their behalf. Specifically,...

We introduce a noncooperative multilateral bargaining model for a network-restricted environment, in which players can communicate only with their neighbors. Each player strategically chooses the bargaining partners among the neighbors to buy out their communication links with upfront transfers....

We investigate the role of networks of military alliances in preventing or encouraging wars between groups of countries. A country is vulnerable to attack if there is some fully-allied group of countries that can defeat that country and its (remaining) allies based on a function of their...

Network structure has a significant role in determining the outcomes of many socioeconomic relationships, including the antagonistic ones. In this paper we study a situation in which agents, embedded in a network, simultaneously play interrelated bilateral contest games with their neighbors....

We develop a continuous time dynamic game to provide with a benchmark theory of Arab Spring-type events. We consider a resource-dependent economy with two interacting groups, the elite vs. the citizens, and two political regimes, dictatorship vs. a freer regime. Transition to the freer regime...
