We present evidence that more ethnically fragmented communities spend, all else equal, more on police services than less fragmented communities. We introduce a model of spending on police services which we use to interpret the data. In this model, we assume that the decision to commit a crime is...

Using a Two-Stage Least Squares procedure, we estimate the relationship between ethnic fragmentation and police spending using a cross-section of United States counties. Our results show that, when controlling for community characteristics and accounting for simultaneity bias, ethnic...

This paper investigates the relationship between ethnic fragmentation and the size of the informal economy. Recent experimental and empirical research links, in turn, ethnicity and trust, and trust and tax compliance. In addition, recent empirical studies have identified an unwillingness to...

Ethnic conflicts and their links to international human trafficking have recently received a surge in international attention. It appears that ethnic conflicts exacerbate the internal displacement of individuals from networks of family and community, and their access to economic and social...

This paper identifies the factors linked to cross-country differentials in growth performance in the aftermath of social conflict for 30 sub-Saharan African countries using panel data techniques. Our results show that changes in the terms of trade are the most important correlate of economic...

Using a unique dataset collected in 59 rural Gambian villages, we study how ethnic heterogeneity is related to the structure of four economic exchange networks: land, labor, inputs and credit. We find that different measures of village-level ethnic fragmentation are mostly uncorrelated with...

Using a unique dataset collected in 60 Gambian villages, I study six social and economic networks: (i) land exchange, (ii) labor exchange, (iii) tool and fertilizer exchange, (iv) credit exchange, (v) matrimonial relationships and (vi) kinship relationships. A variety of measures gleaned from...

Thus far, researchers working on ethnicity and resources as determinants of civil conflict have operated largely independently of each other. While there is plenty of evidence that natural resources may spur armed conflict, empirical evidence for the nexus between ethnic fractionalization and...
