Civil unrest is a powerful form of collective human dynamics, which has led to major transitions of societies in modern history. The study of collective human dynamics, including collective aggression, has been the focus of much discussion in the context of modeling and identification of...

The paper discusses two approaches to spatial equilibrium in the labor market. The more traditional approach of labor economics assumes wage differentials represent arbitrageable differences in utility, with implications 1) that migration should be toward higher wage areas and 2) that migration...

From the streets of Hong Kong to Ferguson, Missouri, civil disobedience has again become newsworthy. What explains the prevalence and extremity of acts of civil disobedience?

This paper addresses two related questions that help to explain geographic variation in access to medical services. The first question examines the existence of agglomeration economies in the hospital service industry. The second considers whether the sharing of intermediate inputs contributes...

We consider a (pure) public goods provision problem with voluntary participation in a quasi-linear economy. We propose a new hybrid solution concept, the free-riding-proof core (FRP-Core), which endogenously determines a contribution group, public goods provision level, and how to share the...
