In the current debate on the future European order, the European Union (EU) is often described as an "emerging federation." This article claims that federalism is not exclusively useful in deliberating about the future of the EU. Non-statecentric conceptions of federalism provide a better understanding of the current structure and functioning of the European system of multilevel governance than most theories of European integration and international relations do. We combine political and economic perspectives of federalism to analyze the "balancing act" between effective political representation and efficient policy-making in the EU. Drawing on the examples of Germany and Switzerland in particular, we argue that the increasing delegation of powers to the central EU level needs to be paralleled by strengthened patterns of fiscal federalism and an empowered representation of functional interests at the European level. Without such "rebalancing," the current legitimacy problems of the EU are likely to intensify. 相似文献

If manufacturing a safer cigarette is technically possible--an open question--then mandating that tobacco manufacturers improve the safety of cigarettes would likely have both positive and negative implications for the nation's health. On the one hand, removing toxins may reduce the incidence of smoking-related diseases and premature mortality in smokers. On the other hand, smokers might be less inclined to quit, those who have quit might resume the habit, and youth who have never smoked will have one less reason to avoid tobacco use. To assess the expected population health impacts of a legislative or regulatory mandate, we created the Tobacco Policy Model, a system dynamics computer simulation model. The model relies on secondary data and simulates the U.S. population over time spans as long as 50 years. Our simulation results reveal that even if requiring cigarettes to be safer makes smoking more attractive and increases tobacco use, a net gain in population health is still possible. 相似文献

The Personal Responsibility and Work Opportunity ReconciliationAct of 1996 (PRWORA) generated renewed interest in welfare racesto the bottom as states received greater discretion over eligibilitystandards for new residents. Despite U.S. Supreme Court decisionsfinding welfare-residency requirements unconstitutional andmounting empirical evidence that welfare benefits do not attractpoor migrants, state policymakers have enacted welfare-reformplans that treat newcomers differently as authorized in PRWORA.This article reviews the existing research on welfare migration,current state-residency requirements, and central constitutionalissues surrounding such requirements. With the likelihood thatcourts will have the final word on the current round of statewelfare-residency requirements, it is essential that empiricalresearch on welfare magnets examine the issues central to thecases currently moving through the judicial system. 相似文献

The authors utilize the two latest ICMA Profile of Local Government Service Delivery Choices surveys to investigate whether the service provision and delivery arrangement information reported in the surveys accurately represents reality and, if not, what factors contribute to generating incorrect or unreliable survey responses. Interviews with practitioners are used to better understand both the accuracy of the survey responses and improvements that could be made to the survey instrument. Results suggest that the ICMA ASD survey data are highly erratic, with more than 70 percent of the cases (N = 70) investigated containing some inaccuracies. A qualitative analysis shows that the majority of the errors appear to be caused by the lack of a clear definition of service provision or by the service titles being too vague or too broad, both of which likely lead to discretion in interpreting survey questions and thus inconsistent answers by individual respondents over time. 相似文献

This paper reflects upon the gross discrepancies between the reassurances given in 2010 by the 2010-2015 UK Coalition Government that their budget and welfare cuts would fall ‘fairly’ across the income spectrum, and the reality of what had happened by the end of that government. It asks how the ‘distributional impact assessment’ provided with the 2010 Comprehensive Spending Review could have been so wrong. In seeking to answer this question, types of systematic bias are considered along with a discussion of ‘marginality’ in assessments of impact. Drawing upon the role of ‘power’ in impact assessment, it traces the ways in which methodological assumptions can eclipse the real life effects of policies behind ‘the average’ as well as by the unfair selection of the ‘unit-of-analysis’. 相似文献

We compare several risk preference elicitation methods – including incentivised, non-incentivised, and framed methods as well as a traditional Likert survey question – in a developing country and empirically test how well consequent measures of risk attitudes predict risk taking behaviour. We find that Likert scale and non-incentivised framed survey questions are not sufficient substitutes for costlier incentivised methods in rural Niger. Instead, the incentivised framed question works best while a simplified incentivised lottery question works almost as well. More risk and ambiguity averse farmers are less likely to adopt fertiliser microdosing indicating the importance of insurance and strategies to promote learning. 相似文献

This article analyses the formation, presentation and reception of two seminal exhibitions: Australian Painting: Colonial, Impressionist, Contemporary (1962–1963) and Canadian Painting 1939–1963 (1964). The presentation of these exhibitions at London’s Tate Gallery reflected the institution’s support for “old dominion” Commonwealth members. The exhibitions also highlight the differing visions of the Canadian and Australian governments concerning the relationship between art, diplomacy and politics during the Cold War. In Canada, Vincent Massey (Governor General 1952–1959) played a key role in ensuring that all forms of Canadian art were promoted internationally. Massey wanted to connect with the European and American avant-garde and to be part of a multiracial Commonwealth. This contrasted with the rather “old-fashioned” views of the Australian prime minister, Robert Menzies, and the Commonwealth Art Advisory Board. They supported a Commonwealth dominated by the “white dominions” and the initial exhibition plan for Australian Painting recalled previous British Empire art shows. The British response to the Canadian and Australian exhibitions is also discussed. British critics preferred the nationally identifiable “exotic” art found in Australian art to the transnational forms of international abstraction in Canadian art. Eventually, Australia “caught up” with Canadian cultural policy following the establishment of the Australia Council. 相似文献
