Reported attitudes towards immigrants are sometimes used as a proxy for ethnic discrimination. However, there is little empirical evidence of a link between attitudes and discrimination. In this paper, we use survey data on people's attitudes towards immigrants combined with data on ethnic...

In this paper we reassess the role of ethnic favoritism in Sub-Saharan Africa. Using data from 18 African countries, we study how primary education and infant mortality of ethnic groups were affected by changes in the ethnicity of the countries' leaders during the last fifty years. Our results...

We analyse interethnic cooperation in an infinitely repeated prisoner's dilemma when members of one group are unable to target punishment towards individual defectors from the other group. We first show that indiscriminate outgroup punishment may sustain cooperation in this setting. Our main...

We study the effect of civil conflict on social capital, focusing on the experience of Uganda during the last decade. Using individual and county-level data, we document causal effects on trust and ethnic identity of an exogenous outburst of ethnic conflicts in 2002-04. We exploit two waves of...

Chay, Guryan and Mazumder (2009) found substantial racial convergence in AFQT and NAEP scores across cohorts born in the 1960's and early 1970's that was concentrated among blacks in the South. We demonstrated a close tracking between variation in the test score convergence across states and...

In a seminal paper Gibbons and Katz (1991; GK) develop and empirically test an asymmetric information model of the labor market. The model predicts that wage losses following displacement should be larger for layouts than for plant closings, which was borne out by data from the Displaced Workers...

We examine peer effects in welfare use among immigrants to Sweden by exploiting a governmental refugee placement policy. We distinguish between the quantity of contacts - the number of individuals of the same ethnicity - and the quality of contacts - welfare use among members of the ethnic...

In the 1980s, many U.S. cities initiated programs reserving a proportion of government contracts for minority-owned businesses. The staggered introduction of these set-aside programs is used to estimate their impacts on the self-employment and employment rates of African-American men. Black...

Despite the importance attributed to the effects of diversity on the stability and prosperity of nations, the origins of the uneven distribution of ethnic and cultural fragmentation across countries have been underexplored. Building on the role of deeply-rooted biogeographical forces in...

We examine peer effects in welfare use among immigrants to Sweden by exploiting a governmental refugee placement policy. We distinguish between the quantity of contacts – the number of individuals of the same ethnicity – and the quality of contacts – welfare use among members of the ethnic...
