Ethnically homogenous communities often do a better job than diverse communities of producing public goods such as satisfactory schools and health care, adequate sanitation, and low levels of crime. Coethnicity reports the results of a landmark study that aimed to find out why diversity has this cooperation-undermining effect. The study, conducted in a neighborhood of Kampala, Uganda, notable for both its high levels of diversity and low levels of public goods provision, hones in on the mechanisms that might account for the difficulties diverse societies often face in trying to act collectively. The Mulago-Kyebando Community Study uses behavioral games to explore how the ethnicity of the person with whom one is interacting shapes social behavior. Hundreds of local participants interacted with various partners in laboratory games simulating real-life decisions involving the allocation of money and the completion of joint tasks. Many of the subsequent findings debunk long-standing explanations for diversity’s adverse effects. Contrary to the prevalent notion that shared preferences facilitate ethnic collective action, differences in goals and priorities among participants were not found to be structured along ethnic lines. Nor was there evidence that subjects favored the welfare of their coethnics over that of non-coethnics. When given the opportunity to act altruistically, individuals did not choose to benefit coethnics disproportionately when their actions were anonymous. Yet when anonymity was removed, subjects behaved very differently. With their actions publicly observed, subjects gave significantly more to coethnics, expected their partners to reciprocate, and expected that they would be sanctioned for a failure to cooperate. This effect was most pronounced among individuals who were otherwise least likely to cooperate. These results suggest that what may look like ethnic favoritism is, in fact, a set of reciprocity norms—stronger among coethnics than among non-coethnics—that make it possible for members of more homogeneous communities to take risks, invest, and cooperate without the fear of getting cheated. Such norms may be more subject to change than deeply held ethnic antipathies—a powerful finding for policymakers seeking to design social institutions in diverse societies. Research on ethnic diversity typically draws on either experimental research or field work. Coethnicity does both. By taking the crucial step from observation to experimentation, this study marks a major breakthrough in the study of ethnic diversity. A Volume in the Russell Sage Foundation Series on Trust

Most aspects of South Africa's investment climate the location-specific factors that shape opportunities and incentives for firms to invest productively, create jobs, and grow are favorable. The majority of large, registered firms believe that the legal system is able to protect their property rights. Infrastructure is reliable. Tax rates are relatively low. The burden of regulation is comparable to other middle-income countrries. Few firms pay bribes. And most firms have adequate access to credit. In many dimensions, South Africa has a good investment climate. Consistent with this, large South African firms are very productive. Labor productivity is far higher than in the most productive low-income countries in Sub-Saharan Africa and compares favorably with other middle-income countries such as Brazil, Lithuania, Malaysia, and Poland. And although labor productivity in South Africa is slightly lower than in the most productive cities in China, it is over three times higher than in China as a whole. So, why hasn't South Africa been growing faster? As this title explores, while the investment climate is generally favorable, some problems remain. Firms appear to be particularly concerned about four areas: difficulty hiring skilled and educated workers, rigid labor regulations, exchange rate instability, and crime. Using rigorous statistical information on these and related topics, the book aims to assist policy makers and private sector stakeholders in developing reforms that will improve firm performance and growth.
