The hypothesis that political violence deters tourism is mainly based on case study evidence and a few quantitative studies confined to a small sample of countries. Two estimation techniques—a fixed-effects panel estimator with contemporaneous effects only and a dynamic generalized method...

The existing literature identifies natural resource wealth as a major determinant of civil war. The dominant causal link is that resources provide finance and motive (the “looting rebels†model). Others see natural resources as causing “political Dutch disease,†which in turn...

Underlying several theories of European integration is the idea that countries' willingness to sign up to supranational rules is dependent on the expectation and/or realization of various benefits. In this paper, we explore whether such benefits also affect member states' implementation of these...

This article argues that the link between income inequality and violent property crime might be spurious, complementing a similar argument in prior analysis by the author on the determinants of homicide. In contrast, Fajnzylber, Lederman & Loayza provide seemingly strong and robust evidence that...

This article tests the hypothesis that democracies exhibit stronger international environmental commitment than non-democracies, using multivariate econometric techniques. A number of proxy variables are used in lieu of environmental commitment, a non-observable variable. Strong evidence is...

The newly established International Criminal Court (ICC) promises justice to the victims of genocide, war crimes and crimes against humanity. Past offenders can be punished, while future potential offenders may be deterred by the prospect of punishment. Yet, justice is no substitute for...

This study investigates whether ethnic and other forms of social diversity affect militarization of society. Recent scholarship in economics finds that high diversity leads to lower provision of public goods. At the same time, many conflict studies find that highly diverse societies face a lower...

The Stern Review on The Economics of Climate Change is one of the few cost-benefit analyses of climate change to come out in favour of immediate and decisive action to reduce greenhouse gas emissions. The choice of a low discount rate is the main reason for the Review’s divergence in...

We analyze the spread of policies dealing with international trafficking in human beings. Arguing that countries are unlikely to make independent choices, we identify pressure, externalities and learning or emulation as plausible diffusion mechanisms for spatial dependence in anti-trafficking...

The authors discuss how scholars can bring theories of spatial policy dependence and empirical model specifications closer in line so that the empirical analysis actually tests the theoretical predictions. Comprehensive theories of spatial policy dependence typically suggest that the...
