We reassess the results from the literature on the relationship between the youth unemployment rate and GDP growth (Okun’s law), based on the concern that the unemployment rate is not an ideal indicator for teenagers and young adults. Using the unemployment ratio instead, we find that youth unemployment (15–24 years old) is not significantly more responsive to economic growth than prime-age (25–64) unemployment. However, compared to prime-age unemployment, teenagers’ unemployment (15–19) is relatively unresponsive, whereas young adult’s (20–24) unemployment is more strongly correlated with economic growth. These results are quite different than those obtained with the unemployment rate as the dependent variable. 相似文献

A cap on global warming implies a tighter carbon budget which can be enforced with a credible second-best renewable energy subsidy designed to lock up fossil fuel and curb cumulative emissions. Such a subsidy brings forward the end of the fossil fuel era but accelerates fossil fuel extraction and global warming in the short run. A weaker fossil fuel oligopoly implies that anticipation of a given global carbon budget induces fossil producers to deplete reserves more voraciously and accelerate global warming. This race to burn the last ton of carbon is more intensive for the feedback than open-loop Nash equilibrium, so that the Green Paradox effect of a renewable energy subsidy is stronger. There is an intermediate phase of limit pricing to keep renewable energy producers at bay, which becomes much more relevant when a cap on global warming is enforced. A stronger fossil fuel oligopoly lengthens the period of limit pricing and typically brings forward the carbon-free era. Finally, the mere risk of a cap on global warming being enforced at some unknown, future date makes fossil fuel extraction more voracious and accelerates global warming. 相似文献

被马克思主义经典作家寄予极高道德期望的“计划经济”.因被误解误用而使社会主义道德建设付出代价,造成崇高的道德理想与经济社会发展状况之间、道德的人性预设与人的物质存在之间、先进的政治理念与官僚主义极权现实之间的重大落差。重新思考计划经济的道德代价得到如下启示:先进的理论不能脱离现实的实践.不能不顾现实任意修订或者恶意篡改理论;不能放弃计划经济理念的道德理想意蕴,应充分发挥“计划”要素在市场经济中的引导作用;要借助于经济体制的完美设计,而不是用政治意识形态的理想化宣传来解决道德问题。 相似文献

通过对20世纪特别是90年代以来学术界关于"女性文学"这一概念内涵理解及界说的大致梳理,重点对90年代该概念内涵的界说所存在的悖论提出质疑,从而提出界定一部(或一篇)文学作品是否属于"女性文学",主要应以作品内涵而不是以作者性别为依据. 相似文献

新新贸易理论框架下异质性企业出口和生产率的关系可以用两种假说来概括——"自我选择出口"和"出口导致增长"。文章回顾了十多年来学者们用各个国家的企业数据对这两种假说的验证,对比和评析了相关的研究方法、研究结论、实证结果的原因等,对我国出口企业"生产率悖论"的原因进行总结与探讨,并提出了未来的研究思路与方向。 相似文献

As the importance of servitization and service-augmented solution delivery grows into a mainstream phenomenon for manufacturers, offering theoretically founded avenues to solve their specific internationalization challenges is necessary. The study addresses the internationalization paradox faced by servitized manufacturers generated by the specific hybrid nature of their product-service offering. As such, this research is meant to understand the entry mode diversity for the internationalization of advanced servitization providers. Our primary research deal-level data follows 1885 potential sales negotiations for servitized products closed in 2018 by a Poland-based multinational high-tech optics firm offering product-service systems. The results of the study support the idea that manufacturers of advanced servitization could benefit from the implementation of entry mode diversity. It is found that the sales deal success when entry mode diversity is implemented in a foreign market is positively moderated when knowledge-intensive advanced servitization is included in the negotiation. 相似文献

Data privacy is a threat to the future of e-commerce. Consumers face a dilemma in balancing the risks and benefits associated with online privacy, leading to a phenomenon termed the privacy paradox. The study interviewed 30 Millennials representing 13 countries using a grounded theory approach to explore the influence of national culture on the information disclosure attitude in the context of online retailing. The study presents a novel framework, Privacy Paradox Pyramid, to manage the privacy paradox through the lens of national culture, enabling retailers to segment the customers and design a tailored approach to create a competitive advantage. 相似文献

中国出口企业“生产率悖论”存在性检验——来自2005~2008年中国制造业企业的证据 总被引:1,自引:0,他引:1
在异质性企业贸易理论提出后,对中国企业生产率的计算认为中国存在出口企业的生产率悖论,即出口企业的生产率比非出口企业的生产率要低。但是测算只是运用了求企业生产率的平均值的方法,这不能反映出口企业与非出口企业的生产率整体状况。文章使用2005~2008年中国制造业企业数据,运用总量法和均值法分行业、分地区计算并比较出口企业与非出口企业的生产率,从而检验中国出口企业生产率悖论的存在性。最后实证检验生产率与企业出口规模的相关性,结论显示生产率与企业出口是负相关的,这也是一种检验生产率悖论存在性的方法。 相似文献

The referendum (or compound majority) paradox occurs when the majority of voters in the majority of districts supports an issue/candidate but the majority of voters across all districts opposes the same issue/candidate (or vice versa). We calculate the likelihood of this social choice anomaly for any (possibly large) odd number of districts and any (possibly large) odd number of voters per district. The likelihood of the paradox is close to 50% when the issue/candidate is divisive (voters across all districts are split almost 50%–50%). The paradox virtually disappears when the issue/candidate is supported/opposed by at least two-thirds of all voters. 相似文献
