Electoral district magnitude varies across German electoral constituencies and over legislative periods due to Germany’s electoral system. The number of seats in parliament per constituency is effectively random. This setting permits us to investigate exogenous variations in district magnitude...

I analyze the effects of ethnic divisions on the provision of public goods. Using OpenStreetMap data, I construct a new global dataset of locations of public amenities, such as schools, hospital and libraries. I allow for the possibility that the data may be systematically incomplete using two...

We identify the causal effect of a reduction in military personnel on a number of socioeconomic indicators within the periphery of the military base. The base realignments and closures (BRACs) within the German armed forces is an exogenous source of variation that allows for the estimation of...

This paper empirically analyses the relationship between terror incidents and internal migration in Israel. Using a newly created database of region-to-region migration flows for the years 1998-2012, the empirical model regresses the annual flow of migrants from an origin subdistrict to a...

This paper analyses the impact of terrorism on tax enforcement policies by focusing on the case of the Basque Country. The presence of externalities in tax administration attributable to the costs of terrorism is investigated by undertaking a theoretical analysis. The findings of this are tested...

This paper examines the role of ethnic-based gender norms in explaining the occurrence and intensity of sexual violence in conflict. We generate a novel dyadic dataset that contains information on the ethnic identity of the actors involved in 33 ethnic civil conflicts in Africa between 1989 and...

This paper proposes three theoretical mechanisms through which polygyny may be related to social unrest. The mechanisms are related to different dimensions of grievance-inducing and, partly, greed-related inequality, which may occur in polygynous societies. These dimensions include (i) economic,...
