The conflict in Northern Ireland was an example of "complex warfare" with both insurgency and sectarian violence. We present a unified model that helps to identify these two forms of conflict from the spatial distribution of violence. The model predicts that tectonic boundaries between...

This chapter introduces the author's selected papers on the economics of coercion and conflict. It defines coercion and conflict and relates them. In conflict, adversaries make costly investments in the means of coercion. The application of coercion does not remove choice but limits it to...

This paper analyzes whether the propensity to secede by subnational regions responds mostly to differences in income per capita or to distinct identities. We explore this question in a quantitative political economy model where people's willingness to finance a public good depends on their...

We study how NAFTA changed the geography of violence in Mexico. We propose that this open border policy increased trafficking profits of Mexican cartels, resulting in violent competition among them. We test this hypothesis by comparing changes in drug-related homicides after NAFTA's introduction...

This paper empirically investigates the effects of Anti-Open Grazing Laws (AOGLs) on herder-farmer conflicts in Nigeria. The laws, enacted as a response to escalating violent conflicts over fertile land resources between herders and farmers, aimed to reduce clashes by prohibiting livestock...

We examine the relationship between household income and happiness in Afghanistan and the moderating roles of fear of insecurity and experiencing violence. Our study is based on surveys conducted by the Asia Foundation from 2014 to 2021 across 34 provinces in Afghanistan. Employing fixed effects...

This paper investigates whether distributional conflicts become more likely when groups are involved in the fight. We present results from a laboratory experiment in which two parties can appropriate resources via a contest or, alternatively, take an outside option. Keeping monetary gains...

Using multiple waves of Statistics Canada's Canadian Community Health Survey (CCHS) linked with the Longitudinal Immigration Database (IMDB), as well as the Uppsala Conflict Data Program (UCDP)/ International Peace Research Institute in Oslo (PRIO) Armed Conflict Dataset, we examine the effect...

This paper considers evolutionarily stable decisions about whether to initiate violent conflict rather than accepting a peaceful sharing outcome. Focusing on small sets of players such as countries in a geographically confined area, we use Schaffer's (1988) concept of evolutionary stability. We...
