在关于货币政策影响经济主体风险承担水平,进而影响金融周期波动机制的研究中,基于风险承担渠道的相关研究较为成熟.区别于以往相关研究多关注货币政策实际采取的立场,文章基于货币政策反应函数渠道探讨了数量型与价格型货币政策反应函数对金融周期波动影响的时变机制.滚动回归的实证结果显示:无论数量型货币政策规则还是价格型货币政策规则,货币政策对信贷波动反应的敏感性主要影响金融周期的波动,但在价格型货币政策规则下,基于信贷视角观察金融周期波动时,货币政策信贷敏感性与货币政策资产价格敏感性对金融周期影响差异较小;较之于价格型货币政策规则,货币政策对信贷波动反应的敏感性在数量型货币政策规则下,对金融周期波动的影响更显著,并在一定程度上表现出随时间扩大的趋势.文章的创新之处在于:强调了货币政策通过政策反应函数渠道而非以往研究中较多关注的狭义风险承担渠道影响金融周期波动的事实,并构建计量模型对货币政策反应函数渠道影响金融周期波动的时变机制进行了详细刻画.  相似文献

The generalized half-normal (GHN) distribution and progressive type-II censoring are considered in this article for studying some statistical inferences of constant-stress accelerated life testing. The EM algorithm is considered to calculate the maximum likelihood estimates. Fisher information matrix is formed depending on the missing information law and it is utilized for structuring the asymptomatic confidence intervals. Further, interval estimation is discussed through bootstrap intervals. The Tierney and Kadane method, importance sampling procedure and Metropolis-Hastings algorithm are utilized to compute Bayesian estimates. Furthermore, predictive estimates for censored data and the related prediction intervals are obtained. We consider three optimality criteria to find out the optimal stress level. A real data set is used to illustrate the importance of GHN distribution as an alternative lifetime model for well-known distributions. Finally, a simulation study is provided with discussion.  相似文献

This article estimates the value of a statistical life (VSL) for Chile under the hedonic wage method while accounting for individual risk preferences. Two alternative measures of risk aversion are used. First, risk aversion is directly measured using survey measures of preferences over hypothetical gambles, and second, over observed individual behaviors that may proxy for risk preferences, such as smoking status, are used. I reconcile the results with a theoretical model of economic behavior that predicts how the wage‐risk tradeoff changes as risk aversion differs across individuals. The VSL estimates range between 0.61 and 8.68 million dollars. The results using smoking behavior as a proxy for risk attitudes are consistent with previous findings. However, directly measuring risk aversion corrects the wage‐risk tradeoff estimation bias in the opposite direction. The results are robust to other observed measures of risk aversion such as drinking behavior and stock investments. Results suggest that, consistent with the literature that connects smoking behavior with labor market outcomes, smoking status could be capturing poor health productivity effect in addition to purely risk preferences.  相似文献

挖掘特定产品的需求模式无法从整体掌握该类产品的市场特征;短生命周期体验品因缺乏历史销售数据,并且销售总量波动性极大,尤其需要从整体掌握销售总量与产品属性间关系的需求特征规律,但又难以挖掘,亟待提出适用于该类产品的需求特征模式挖掘方法。基于按销售总量分区后各区的需求特征的规律性,提出了一种按销售总量分区、以已有产品介绍集和销售总量为源信息、适用于新产品开发前使用、融合内容分析和关联分析的短生命周期体验品需求特征模式挖掘方法。该方法包括基于内容分析法的产品属性挖掘方法和基于关联分析的产品属性关系模式挖掘方法。前者可以得到较全面的产品属性;后者能够构建不同销售总量区间内产品集的属性关系模式,得到各区间的产品属性关系网,获得高销售总量区间具备,但中、低区间不具备的属性关系模式,从而获得需求特征模式。通过不断更新产品介绍集和销售总量并迭代挖掘,该方法能够动态挖掘需求特征模式。最后利用2013至2016年国产犯罪和爱情类电影数据验证了该方法的可行性,并得到了这两类电影的产品属性及近年的需求特征模式,可用于指导这两类电影的创作。  相似文献

企业信息安全法律治理可有效保障国家网络与信息安全,捍卫个人权益,促进产业在"安全"中得以"发展"。我国相关立法中规定的企业安全保护义务多为静态性、措施性的管理性义务,不足以防御多变的安全风险;企业安全法规遵从激励机制缺失,合规动力不足;企业信息安全文化的普及力度欠缺。解决以上难题,应基于"法律治理"思维,将"法人治理"定位为企业信息安全法律治理的重心。在制度设计层面,适当借鉴美国企业信息安全法律治理在立法监管与企业自治中的有益经验,以信息安全法律治理的基本原则为指引,充分发挥立法激励作用,鼓励所有企业建立强制与自愿相结合的信息安全"法人治理"结构,对企业董事、高官人员的信息安全义务之履行予以充分重视,增强企业信息安全文化建设,凸显安全文化的价值。  相似文献

This paper focuses on how immigrant women experience and negotiate their everyday life with children prior to and after leaving a violent partner. Twenty‐three women staying at domestic violence and abuse shelters with their children were interviewed about their experiences with assistance services and their everyday life with their children. At the time of the interviews, most of the women were legally separated or divorced and were either living in or in touch daily with shelters. In this paper, we look at some of the challenges that women face when exposed to violence in a relationship that involves children. Being exposed to violence from a partner raises a number of economic, practical, and emotional concerns, both prior to and after leaving. For the mothers in our study, maintaining a regular routine is key to making the children feel safe in an unpredictable setting. For many, economic dependence on the partner is replaced with economic dependence on assistance services after leaving the partner. Services must recognize that providing help to mothers who have left a violent partner constitutes more than just practical support but is crucial for mothers' ability to re‐establish a predictable everyday life with their children.  相似文献

《1844年经济学哲学手稿》和《神圣家族》都是马克思主义创始人早期思想的代表性著作,二者都把“生活”作为重要概念进行论述。从作为经济学哲学概念到作为社会批判概念,马克思主义创始人对“生活”的认识经历了从对物质生产活动的重视到对无产阶级普遍贫困生活的揭露,从分析“生产生活”的异化到对“非人性”生活的批判,从“生活的手段”到消灭“非人性的生活条件”的思想历程。人类的历史是人类生活发展的历史。解决人的美好生活如何实现的问题,在马克思恩格斯的生活思想中居于核心地位,这对当今中国具有重要的理论指导价值。中国特色社会主义进入新时代,从开启一种全新文明的生活形态的高度来理解新时代的美好生活,才能准确把握我国社会主要矛盾变化的深刻意义。  相似文献

ABSTRACT

Despite a symbolic shift toward ‘emotional taint’ in dirty work literature, the role of the workplace has not been studied in relation to socially admired professions, such as corporate social responsibility (CSR) work. This article carries out an in-depth, critical examination of CSR as an emotionally tainted occupation in Japan. Its findings, substantiated by an analysis of 34 CSR workers’ rhetoric, help conceptualise ‘internal uselessness’. This emerges when workers feel their organisations publicly foster an image of their work that is decoupled from its internal reality, assigning them chief tasks they consider irrelevant. This leads to negative consequences that damage their workplace social relationships, professional aspirations and emotional well-being. The findings ultimately show that these CSR workers in Japan attempt to counterbalance internal uselessness through a social quest with peers outside their workplace, but also manage their emotions by rationalising their job status as inescapable, influenced by situated commitment norms.  相似文献

As the international guardian of social justice, the ILO is witnessing a global revolution in accounting, which has culminated in international accounting standards (IAS-IFRS). Previously, accounting measured the economy in relation to the capacities and responsibilities of workers and their employers. Today, the exact opposite is the case: the IAS-IFRS no longer measure work and enterprises, referring instead to the abstract concept of a cybernetic entity capable of constant restructuring, at the cost of unprecedented inequality. The author points to the incoherence of this system and to the need to restore the full carrying value of labour.  相似文献

Abstract

Objective: Attention deficit hyperactivity disorder (ADHD) negatively influences various aspects of life such as social relations, adaptive skills, and occupation. In addition, many university students experience sleep problems, academic failure, and low quality of life (QOL). We investigated the relationship among ADHD symptoms, sleep quality, and QOL of college students, and identified the factors related to their QOL. Participants and Methods: Using a survey questionnaire, data were collected from 195 students from March–May 2017. Results: QOL of students was related to ADHD symptoms and sleep quality. Factors significantly associated with better QOL were fewer ADHD symptoms, good sleep quality, male sex, high academic performance, and high economic status. The explanatory power of these variables on QOL was 32.0%. Conclusion: To improve the QOL of college students, a multifaceted approach that includes assessment of ADHD symptoms and sleep quality is needed.  相似文献
