This paper studies the formation of self-enforcing global environmental agreements in a world economy with international trade and two groups of countries that differ with respect to fuel demand and environmental damage. It investigates whether the signatories' threat to embargo (potential) free...

Countries can reduce global emissions by reducing own consumption since they are linked to the total value of consumption world wide. Two effects are at issue: a utility loss from forgone consumption and a utility gain from lowered temperature change. It is thus unclear whether own country...

This paper studies the influence of interregional inequality within countries on internal con-flicts. Regional inequalities are measured by the population-weighted coefficient of variation of regional GDP per capita. As the main innovation, I use a panel data set of country-level re- gional...

This paper reviews the economics approach to conflict and national borders. The paper (a) provides a summary of ideas and concepts from the economics literature on the size of nations; (b) illustrates them within a simple analytical framework where populations fight over borders and resources,...

Using high-resolution data from Africa over the period 1998-2012, this paper investigates the hypothesis that a higher exposure to malaria increases the incidence of civil violence. The analysis uses panel data at the 1o grid cell level at monthly frequency. The econometric identification...

We reconsider the relationship between oil and conflict, focusing on the location of oil resources. In a panel of 132 countries over the period 1962-2009, we show that oil windfalls increase the probability of conflict in onshore-rich countries, while they decrease this probability in...

This paper proposes a difference-in-differences approach for disentangling a total treatment effect on some outcome into a direct effect as well as an indirect effect operating through a binary intermediate variable – or mediator – within strata defined upon how the mediator reacts to the...

We combine original geo-referenced data on mining extraction of 15 minerals with information on conflict events at spatial resolution of 0.5o x 0.5o for all Africa over 1997-2010. Exploiting exogenous variations in world prices, we find a positive impact of mining on conflict at the local level....

During the past two centuries, western nations have successively extended the voting franchise to citizens of lower income. We explain this process of democratization as a rational way for incumbent elites to wage war effectively on other nations, as in a strategic game of international conflict...
