I report estimates for a fixed-effects model of country-level Gini coefficients as a function of economic freedom along with relevant control variables. Gini coefficients are drawn from the UNU/WIDER World Income Inequality Database Version 2.0a, while economic freedom is measured by the Fraser Institute's Economic Freedom of the World index. Controls are included for per capita income, political structure, education, demographics, and industrial composition. Over a broad range of freedom, the estimated relation between economic freedom and income inequality is positive, statistically significant, but relatively inelastic. 相似文献

A key question in understanding regulation through independent intermediaries is the extent to which intermediary actions are either coordinated, thereby supporting consistency in regulatory application, or uncoordinated, leading to monitoring and enforcement disparities. This paper examines professional associations as one mechanism by which policy action may be coordinated in decentralized arrangements. Professional associations provide means and venues for members to interact, offer training and education that develops shared understanding of policy directives, are collective representation bodies for professional members, and may play an important role in establishing and enforcing collective standards for appropriate behavior. We examine these functions in the decentralized administration of United States organic food certification, focusing on two relevant professional associations – the Accredited Certifiers Association and the International Organic Inspectors Association. Drawing on multiple methods, including interviews and survey data, our findings indicate that professional organic certification associations provide valuable education and training, disseminate information, and facilitate knowledge sharing among administrative entities and with regulatory authorities. We conclude with a discussion of the prospects and limitations of professional associations for third‐party regulation, and how accounting for professional association functions can improve our understanding of regulatory intermediary coordination and conduct. 相似文献

Among the more recognizable programs related to natural and sustainable food is the United States Department of Agriculture’s National Organic Program. Although the robustness of the organic food market is difficult to contest, many debate the extent to which U.S. organic policy outcomes adequately serve consumers and the organic agriculture producers they rely on. This paper engages the debate from the perspective of certified organic producers. Drawing on the results of a nationwide survey of USDA‐certified producers, we first provide a snapshot of how producers assess the environmental, consumer, and market impacts of U.S. organic food policy. We then examine the extent to which organic producers’ policy impact perceptions are associated with their alignment with an “organic ethos”—understood as producers’ commitment to core organic principles and the organic movement. The paper highlights producers’ values as perceptual filters and cognitive mechanisms that help shape producers’ policy impacts perceptions, illustrating a contributing factor to the enduring nature of organic policy debates. 相似文献

<正>Remember the days when people used to have a phone,a computer and a camera?I do,simply because it wasn’t that long ago.However,as technology hurtles along at the speed of light,it might have escaped some people’s attention that these three devices now come together in the form of a smartphone. 相似文献

The use of Internet filters in public classrooms in the USA has been intensely debated, both in terms of its effectiveness and legality. The debate pits concerns to protect students from indecent material against issues of unconstitutional censorship. This paper examines the legal issues addressed in various rulings by the US Supreme Court pertinent to issues raised in the debate over the constitutionality of filtering in the classroom. The rulings and opinions offer valuable insights into the legal issues raised in this debate. 相似文献

In a recent critique and elaboration of general strain theory, Agnew (2001) argued that criminal victimization might be among the most consequential strains experienced by adolescents, and therefore might be an important cause of delinquency. Few studies to date, however, had examined victimization as a potential cause—rather than outcome—of delinquency. This article addresses this void by examining predictions from general strain theory about the effects of victimization on later involvement in delinquency. The analyses indicated that violent victimization significantly predicted later involvement in delinquency, even when controlling for the individual's earlier involvement in delinquency. Moreover, general strain theory appears to be a useful theoretical framework for examining this relationship. The effects of victimization on delinquency were explained in part by its effects on anger (the key intervening variable specified by the theory). Partial support also emerged for the theory's hypothesis that the effects of strain should be conditional upon other factors. Specifically, the effects of victimization were marginally greater for juveniles with weak emotional attachment to their parents and significantly greater for those low in self-control. 相似文献

This study uses public-domain documents to describe the complicity of government actors (including current and former environmental regulators) with organized criminals, in facilitating crimes against the environment within two waste industries of New York State. Qualitative analysis results indicate that a combination of changing market forces, inadequate environmental regulation, and various failed policies and practices of the New York Department of Environmental Conservation can explain the presence, activities, and resilience of organized crime in the construction and demolition debris disposal, and also medical waste incineration industries, as well as provide some preliminary recommendations for preventing further regulatory failure in that state. 相似文献
