This paper investigates to what extent socioeconomic status (SES)‐based affirmative action in college admissions can produce racial diversity. Using simulation models, we investigate the racial and socioeconomic distribution of students among colleges under the use of race‐ or SES‐based affirmative action policies, or targeted, race‐based recruitment policies. We find, first, that neither SES‐based affirmative action nor race‐targeted recruiting on their own produce levels of racial diversity achieved by race‐based affirmative action. However, the two policies in combination, although likely expensive, may yield racial diversity comparable to race‐based affirmative action. Second, the use of affirmative action policies by some colleges reduces the diversity of similar‐quality colleges without such policies. Third, the combination of SES‐based affirmative action and race recruiting results in fewer academically‐overmatched Black and Hispanic students than under race‐based affirmative action, but the schools that use both also see a reduction in the academic achievement of enrolled students.  相似文献

While the fertility effects of improving teenagers’ access to contraception are theoretically ambiguous, most empirical work has shown that access decreases teen fertility. In this paper, we consider the fertility effects of access to condoms—a method of contraception not considered in prior work. We exploit variation across counties and across time in teenagers’ exposure to condom distribution programs in schools. We find that access to condoms in schools increases teen fertility by about 12 percent. The results suggest that the effects of condom access varied significantly across different programs; the positive fertility estimates are driven by communities where condoms are provided without mandated counseling. Programs that mandated counseling have zero or negative fertility effects, but estimates on these counties are less robust across specifications.  相似文献

We introduce experimental research design to the study of policy diffusion in order to better understand how political ideology affects policymakers’ willingness to learn from one another's experiences. Our two experiments–embedded in national surveys of U.S. municipal officials–expose local policymakers to vignettes describing the zoning and home foreclosure policies of other cities, offering opportunities to learn more. We find that: (1) policymakers who are ideologically predisposed against the described policy are relatively unwilling to learn from others, but (2) such ideological biases can be overcome with an emphasis on the policy's success or on its adoption by co‐partisans in other communities. We also find a similar partisan‐based bias among traditional ideological supporters, who are less willing to learn from those in the opposing party. The experimental approach offered here provides numerous new opportunities for scholars of policy diffusion.  相似文献

In the United States participatory budgeting (PB) is a relatively new and innovative approach to municipal budgeting that has implications for improving the role of citizen participation in the budgetary process. The research is based on personal interviews with local community leaders involved in the PB process in the 49th Ward of Chicago, Illinois; the 6th Ward of St. Louis, Missouri; and the City of Boston, Massachusetts. Highlights are provided of the specific experiences and perceptions of these community leaders with a particular emphasis on the use of social media platforms in engaging citizens in the PB process. This article concludes with recommendations for creating a PB infrastructure, for increasing citizen participation in the PB process, and for assessing and increasing the impact of PB in cities within the United States.  相似文献

Based on anthropological field work in southeastern Nigeria, this paper explores the public concerns and everyday experience of corruption in a society still living with the legacies of the Biafran secession attempt. The paper shows how the revival of Igbo nationalism and resentment over perceived marginalisation is fuelled by perceptions that the corrupt machinery of the federal government runs against the interests of the Igbo people, and funnels resources away from the southeast as punishment for the failed separatist struggle more than 40 years ago. Hence, complaints about corruption are used to critique the Nigerian state and other regional or ethnic groups, but they also figure in an internally focused critique by Igbos of their own complicity in Nigeria’s endemic corruption.  相似文献
