The launch of the euro in 1999 was assumed to enhance macroeconomic convergence among EMU economies. We test this hypothesis from a comparative perspective, by calculating different indices to measure the degree of macroeconomic dispersion within the Eurozone, the UK and the USA (1999–2019). We use common factor models to produce a single index for each monetary area out of different measures of dispersion. These indices can be used to inform on the degree of optimality of a monetary area. Our results show that macroeconomic dispersion in the Eurozone increased notably even before 2007 and it took significantly longer to return to pre-crisis levels, as compared to the UK and the USA. The paper shows the critical role played by the ECB’s asset purchases programmes in reducing macroeconomic divergences among EMU member states since 2015.  相似文献

利用陕西省安康、商洛和宝鸡3市38家烤烟专业合作社的调查数据,基于不同法人治理结构视角,运用层次分析法构建绩效评价指标体系对两种不同类型的烤烟专业合作社进行实证分析。研究结果表明:38家烤烟专业合作社可以根据法人治理结构的不同分为“外部委托代理人型”与“内部委托代理人型”两种类型。“外部委托代理人型”烤烟专业合作社在社员人数、理事会核心成员构成比例、股权集中程度及监督力度等法人治理结构方面具有明显的优势,在吸纳了更多的农户入社、提高烤烟专业合作社经济收益的同时,也保证了绝大多数农户在股权分配、民主决策参与及合作社监督等方面的权利。这有利于基层民主的完善,有利于显著提高烤烟专业合作社管理效率,从而提高农户整体烟叶生产水平。因此,改善法人治理结构是促进农民专业合作社发展的重要途径。  相似文献

This study takes an exploratory, qualitative approach to examine college students’ perceptions about divorce in the media. Findings suggest that participants perceived both positive and negative representations of divorced families in the media they consume, highlighting the complex nature of navigating and communicating through a divorce. Specifically, college students reported on aspects of the ex-spousal relationship, how children are affected, and the contrast between life pre- and postdivorce. An inductive theme analysis revealed several positive and negative media representations of divorce. Largely, college students perceive media messages about divorce to be accurate portrayals and impactful representations.  相似文献

This study contributes to the growing body of literature on the outcomes of labour migration by focusing on the effects of migrant legal status on the economic and perceptual measures of migration success. To study the effects of legal status, we use a sample of Central Asian migrant women who work in Russia and of their native counterparts who occupy the same positions on the labour market. Similar to the studies in the developed settings, we find that a temporary legal status is associated with an earnings penalty and that permanent legal status corrects this earning disparity. We also find that both temporary and permanent migrant status is positively associated with perceptions of pay inequality but that, irrespective of these perceptions, both types of migrants are more likely to be satisfied with their jobs than natives. We interpret these findings within the legal and social context of migrant economic incorporation in Russia and relate them to the findings from other migrant-receiving settings.  相似文献

While child welfare practitioners in many countries are struggling to develop methods of effective family engagement, they operate within different national and cultural contexts that influence, both positively and negatively, the ability to engage with families. Increasingly, international comparisons are necessary to further understanding of the development of social work practice. This is particularly necessary because most countries utilize international frameworks (such as the United National Convention on the Rights of the Child) to provide guidance in the development of policies, programs, and interventions. Each country (and locality) struggles to advance practice to be more effective and humane. Our paper offers a comparative analysis focused on family-oriented and rights-based frameworks of different countries. Based on a review of current national policies and a review of the literature regarding family-based practices, we examine similarities and differences among four countries: the United Kingdom, Sweden, the United States, and South Korea. These countries were selected because they have some similarities (advanced industrialized democracies, professional social work, and formal child protection systems) but have some differences in their social welfare systems (policies, specific practices, and socio-cultural context). These differences can be utilized to advance understanding regarding the promise and potential for family engagement strategies. We then discuss the utility of this comparison for theory-building in the arena of child-care practice and conclude by identifying the challenges and limitations of this work.  相似文献

In a special paired sample case, Hotelling’s T2 test based on the differences of the paired random vectors is the likelihood ratio test for testing the hypothesis that the paired random vectors have the same mean; with respect to a special group of affine linear transformations it is the uniformly most powerful invariant test for the general alternative of a difference in mean. We present an elementary straightforward proof of this result. The likelihood ratio test for testing the hypothesis that the covariance structure is of the assumed special form is derived and discussed. Applications to real data are given.  相似文献

Improved point and interval estimation of the smallest scale parameter of n independent populations following two-parameter exponential distributions are studied. The model is formulated in such a way that allows for treating the estimation of the smallest scale parameter as a problem of estimating an unrestricted scale parameter in the presence of a nuisance parameter. The classes of improved point and interval estimators are enriched with Stein-type, Brewster and Zidek-type, Maruyama-type and Strawderman-type improved estimators under both quadratic and entropy losses, whereas using as a criterion the coverage probability, with Stein-type, Brewster and Zidek-type, and Maruyama-type improved intervals. The sampling framework considered incorporates important life-testing schemes such as i.i.d. sampling, type-II censoring, progressive type-II censoring, adaptive progressive type-II censoring, and record values.  相似文献

A method is proposed in this paper to assess the local influence of minor perturbations for the Sharpe model when the normal distribution is replaced by normal/independent (NI) distributions. The family of NI distributions is an attractive class of symmetric heavy-tailed densities that includes as special cases the normal, t-Student, slash, and the contaminated normal distributions. Since the returns of the market are not observable, the statistical analysis is carried out in the context of an errors-in-variables model. An influence analysis for detecting influential observations (atypical returns) is developed to investigate the sensitivity of the maximum likelihood estimators. Diagnostic measures are obtained based on the conditional expectation of the complete-data log-likelihood function. The results are illustrated by using a set of shares of companies traded in the Chilean stock market.  相似文献

本文结合国际国内研究动态分层次归纳、阐释当前国民经济核算的研究议题。具体包括:以国民账户体系2008版(SNA-2008)为起点的前沿研究,SNA中心框架的灵活运用研究,接驳中国国民经济核算体系(CSNA)及其实务的优化和创新研究,国民经济核算数据的综合应用研究。最后针对中国当前国民经济核算研究方法中存在的一些倾向性问题做讨论,比如是否过分关注与GDP的关联, 如何充分发挥卫星账户的作用等。  相似文献
