This study is the first to explore the short-run impact of armed conflict on firms’ performance and their perceptions of the business environment. We focus on the August 2008 conflict between Georgia and Russia and use the Business Environment and Enterprise Performance Survey data before and...

The Arab Spring has led to very different outcomes across the Arab world. I present a highly stylized model of the Arab Spring to better understand these differences. In this model, dictators from the ethnic or religious majority group concede power if their country is oil-poor, but can stay in...

I propose a game of signed network formation, where agents make friends to coerce payoffs from enemies with fewer friends. The model accounts for the interplay between friendship and enmity. Nash equilibrium configurations are such that, either everyone is friends with everyone, or agents can be...

This paper studies the microeconomic impacts of the political crisis and civil conflict that immediately followed the December 2007 presidential election in Kenya. Income, expenditures, and consumption dramatically declined for a broad segment of the rural population for the duration of the...

We study the problem caused by international transfrontier pollution. Our re-sults are derived from the analysis of an incomplete information, non-cooperative game model of the determination of emissions in a quantity-rationing setting. We model the emission capping negotiations using the best...

Human players in our laboratory experiment received flow payoffs over 120 seconds each period from a standard Hawk-Dove bimatrix game played in continuous time. Play converged closely to the symmetric mixed Nash equilibrium under a one-population matching protocol. When the same players were...

Usually, groups increase their productivity by the specialization of their group members. In these cases, group output is no longer simply a sum of individual outputs. We analyze contests with group-specific public goods that allow for different degrees of complementarity between group...

In this paper we make use of a unique dataset collected in the central train station of Kiel, Germany. A group ticket is used by individual proposers who search for co-travelers to share the ride with shortly before the train departure. The bargaining behavior resembles the Ultimatum game to the...

Strikes by unmanned aerial vehicles, or drones, have been the primary weapon used by the United States to combat the Taliban and Al-Qaeda in Afghanistan and Pakistan. This paper examines the dynamics of violence involving drone strikes and the Taliban/Al-Qaeda in Afghanistan and Pakistan from...

This paper represents the first attempt to formalise the relationship between remittances inflow and social violence by developing a model which predicts that migrants’ remittances would lead to the reduction of social conflict in the recipient economy under the condition that remittances...
