Diversity and Public Goods: A Natural Experiment with Exogenous Residential Allocation

This paper demonstrates the effects of ethnic and religious diversity on the quality of public spaces. Its identification strategy relies on the exogeneity of public housing allocations in France, and thereby eliminates the bias from endogenous sorting. The paper uses micro evidence of social interactions within housing blocks from the representative French Housing survey, which allows for a detailed identification of the channels through which diversity operates. Differentiating among three channels of public goods provision, the paper finds that heterogeneity in the housing block leads to low levels of sanctions for anti-social behavior and low levels of collective action to improve housing conditions, but no losses in public safety.fractionalization, public goods, collective action, discrimination

Identifying barriers to Muslim integration in France

Is there a Muslim disadvantage in economic integration for secondgeneration immigrants to Europe? Previous research has failed to isolate the effect that religion may have on an immigrant family's labor market opportunities because other factors, such as country of origin or race, confound the result. This paper uses a correspondence test in the French labor market to identify and measure this religious effect. The results confirm that in the French labor market, antiMuslim discrimination exists: a Muslim candidate is 2.5 times less likely to receive a job interview callback than is his or her Christian counterpart. A high-n survey reveals, consistent with expectations from the correspondence test, that second-generation Muslim households in France have lower income compared with matched Christian households. The paper thereby contributes to both substantive debates on the Muslim experience in Europe and methodological debates on how to measure discrimination. Following the National Academy of Sciences' 2001 recommendations on combining a variety of methodologies and applying them to real-world situations, this research identifies, measures, and infers consequences of discrimination based on religious affiliation, controlling for potentially confounding factors, such as race and country of origin.Muslim immigrants ; Integration ; France

"One Muslim is Enough!" - Evidence from a Field Experiment in France

Anti-Muslim prejudice is widespread in Western countries. Yet, Muslims are expected to constitute a growing share of the total population in Western countries over the next decades. This paper predicts that this demographic trend will increase anti-Muslim prejudice. Relying on experimental games and a formal model, we show that the generosity of rooted French toward Muslims is significantly decreased with the increase of Muslims in their midst, and demonstrate that these results are driven by the activation of rooted French taste-based discrimination against Muslims when Muslim numbers increase. Our findings call for solutions to anti-Muslim prejudice in the West.discrimination, Islam, France, group salience, experimental economics, economic theory, group threat theory, intergroup contact theory

Response to David Freedman

As Jonathan Swift made mockingly clear, “modest proposals” that purport to solve previously unyielding problems can have horrible implications. Such proposals should be subjected to skeptical analysis. So we are pleased that our proposed random method of case selection for the qualitative component of multi-method research has attracted some skeptical commentary in the research community in political science. And we are very grateful to David Freedman for providing a perspective on our approach. He is especially qualified to do so, as he is a leading statistician who has long worried about inflated claims for statistical methods in the social sciences, and has been a champion of approaches that are sensitive to the particularities of each datapoint

The Social Effects of Ethnic Diversity at the Local Level: A Natural Experiment with Exogenous Residential Allocation

This paper demonstrates the effects of ethnic diversity on social relationships and the quality of public spaces at a very finite neighborhood level. We use detailed block level data on diversity and housing quality from a representative survey on housing in France. We show how and to what extent diversity within a neighborhood can directly affect household well-being and the quality of the common spaces, whereas the previous literature looks at more aggregate outcomes through voting channels. Our identification strategy relies on the exogeneity of public housing allocations with respect to ethnic characteristics in France, to address the bias due to endogenous residential sorting. Diversity is shown to have a negative effect on the quality of local public goods, either due to vandalism, not deterred by other-regarding preferences and social policing, or due to collective action failure to ensure effective property management. However, we find that diversity has no robust effect on public safety at a local level and, if anything, is more related to social anomie

Religion, Terrorism and Public Goods: Testing the Club Model

Can rational choice modeling explain why Hamas, Taliban, Hezbollah and other radical religious rebels are so lethal? The literature rejects theological explanations. We propose a club framework, which emphasizes the function of voluntary religious organizations as efficient providers of local public goods in the absence of government provision. The sacrifices religious clubs require are economically efficient (Iannaccone (1992)), making them well suited for solving the extreme principal-agent problems faced by terrorist and insurgent organizations. Thus religious clubs can be potent terrorists. That explanation is supported by data on terrorist lethality in the Middle East. The same approach explains why religious clubs often choose suicide attacks. Using three data sources spanning a half century, and comparing suicide attackers to civil war insurgents, we show that suicide attacks are chosen when targets are "hard," i.e., difficult to destroy. Data from Israel/Palestine confirm that prediction. To explain why radical religious clubs specialize in suicide attacks we model the choice of tactics by rebels attacking hard targets, considering the human costs and tactical benefits of suicide attacks. We ask what a suicide attacker would have to believe to be rational. We then embed that attacker and other operatives in a club model. The model has testable implications for tactic choice and damage achieved by clubs and other rebels, which are supported by data on terrorist attacks in the Middle East: Radical religious clubs are more lethal and choose suicide terrorism more often, when they provide benign local public goods. Our results suggest benign tactics to counter terrorism by religious radicals.

Diversity and local public goods: a natural experiment with exogenous residential allocation

This paper demonstrates the effects of ethnic diversity on social relationships and the quality of public spaces at a very finite neighborhood level. We use detailed block level data on diversity and housing quality from a representative survey on housing in France. We show how and to what extent diversity among adjacent neighborhoods can affect household well-being and the quality of local public goods, whereas the previous literatura looks at aggregate indicators and outcomes. Our identification strategy relies on the exogeneity of public housing allocations with respect to ethnic characteristics in France, and thereby eliminates bias due to endogenous residential sorting. Diversity is shown to have a negative effect on local public goods, either due to vandalism and to the lack of social policing, or due to collective action failure for maintenance. However, we find that diversity has no robust effect on civil conflict at a local level and, if anything, is more related to social anomie. We test the exogeneity of residential allocation across public housing blocks with respect to ethnic characteristics. We also show that our results are not driven by potential biases from self-reported well-being and that they hold even with objective measures of housing quality
