The paper investigates whether Southern Mediterranean and Middle Eastern markets under the Euro–Mediterranean Partnership (Egypt, Lebanon, Morocco, Malta, and Turkey) have become more financially integrated with the European stock market over time. The findings suggest that the Turkish equity market is moderately integrated with the European market, while the other economies exhibit weak financial integration with Europe, supporting the idea that the partnership appears to have no effect on enhancing inter-market linkages for these economies. Therefore, these markets would be good destinations for international investors seeking attractive investment opportunities to diversify their equity portfolios. Structural changes in the cross-market integration do exist, which may be considered as a guide for international equity portfolio diversification over different subperiods. In addition, there is evidence of an increasing trend in conditional correlations for Egypt and Turkey, to varying degrees, over time, notably during the post global financial crisis of 2007–2008, thus revealing herding behavior during this period. Overall, investors should be wary of the variation of equity market integration over time before engaging in an investment at the level of portfolio management and diversification. Policymakers must be aware of the remoteness of the current achievements of the Euro–Mediterranean Partnership from the targets set in terms of financial development and economic growth.  相似文献

We analyze the Russian restriction on chicken imports as an example of a non-tariff barrier (NTB). Cointegration test results support the hypothesis that the NTB limited trade. We calibrate an equilibrium market model to cointegration results to assess the market impact. The tariff equivalent of the Russian chicken NTB is estimated to be 30  40% depending on the representation of consumer demand. Removing the NTB decreases domestic production by 4–5% and domestic price by 27%–34%, while imports increase by 326–423 thousand tons annually in 2015–2019.  相似文献

This study examined the differences in risk behavior between men and women using a household survey that captured the risk preferences of two members in a household and recorded wealth at the individual level instead of the usual approach of representing wealth at the household level. After controlling for commonly used explanatory variables, such as gender, education, age, and wealth, household fixed effects explain about 15% of the variation in risk behavior. This highlights the magnitude of household effects in shaping one’s risk behavior. In general, females in the study area are more risk averse than males based on a risk game with real payout. The gender differences disappear when focusing on only the top land owners. However, even in those cases, females consider themselves more risk averse, supporting results from previous studies that link culture and societal norms to the gender differences in risk behavior.  相似文献

近年来中日关系逐步转寒回暖,无论政治交流氛围,还是经济合作环境都得到了较大改善,这离不开中国政府根据国际形势及中日关系的变化及时调整对日政策,也充分体现了习近平新时代中国特色社会主义外交思想对中日关系缓和发展的引领作用。在安倍首相访华及习近平主席出席大阪G20峰会之后,两国政府在努力建设契合新时代要求的中日关系上达成多点共识。中日双方将依托“一带一路”倡议和第三方市场合作的平台,进一步致力于深化经济合作,维护多边主义和自由贸易体制,共同培育新动能和新的增长点,加速东北亚区域命运共同体的构建。  相似文献

BackgroundIn Australia the majority of homebirths are attended by privately practising midwives (PPMs). In recent years PPMs have been increasingly reported to the Australian Health Practitioner Regulation Agency (AHPRA) mostly by other health professionals.Purposeto explore the experiences of PPMs in Australia who have been reported to the AHPRA.MethodsA qualitative interpretive approach, employing in-depth interviews with eight PPMs was undertaken and analysed using thematic analysis. A feminist theoretical framework was used to underpin the research.ResultsThe majority of reports made to AHPRA occurred when midwives supported women who chose care considered outside the recommended Australian College of Midwives (ACM) Consultation and Referral Guidelines. During data analysis an overarching theme emerged, “Caught between women and the system”, which described the participants’ feelings of working as a PPM in Australia. There were six themes and several sub-themes: The suppression of midwifery, A flawed system, Lack of support, Devastation on so many levels, Making changes in the aftermath and Walking a tight rope forever. The findings from this study reveal that midwives who are under investigation suffer from emotional and psychological distress. Understanding the effects of the process of investigation is important to improve the quality of professional and personal support available to PPMs who are reported to AHPRA and to streamline processes.ConclusionIt is becoming increasingly difficult for PPMs to support the wishes and needs of individual women and also meet the requirements of the regulators, as well as the increasingly risk averse health service.  相似文献

进入新时期以来,在西方后现代主义思潮的浸染下,我国大学生的价值观发生了嬗变:由单一向多元转变、集体向个人位移、理想向世俗变动,甚至呈现出与我国社会主义核心价值观相背离的风险。后现代主义语境下的这一嬗变,因循于社会结构的变迁和大学生思维的非真实化变动,并深刻地受到大众传媒低俗化的影响。面对大学生价值观取向的变迁,引导大学生正确认识后现代主义思潮、强化大学生价值观再培育、发挥社会主义核心价值观的整合作用显得尤为重要。  相似文献

从金融发展视角研究经济波动属于一个前沿主题。本文归纳了金融发展与经济波动发生联系的理论机制,并对国内外经验文献进行了梳理。总的来看,理论研究与经验研究都未形成一致的结论,因此有关金融发展与经济波动联系的研究仍然是一个有待进一步探索的开放领域。  相似文献

We argue that households’ choice of financial intermediary is conditioned by households’ social network structures and socioeconomic status. Analyses show that households’ social network size and network composition affect their choices by limiting the quality and quantity of information, resources, and social influence one can access through social ties. Moreover, we find that high-SES families favor formal intermediaries due not only to their richer financial knowledge, higher affordability, and greater capacity to repay loans, but also to their high demands and special types of financial needs that can hardly be satisfied by embedded resources.  相似文献

互联网时代第三方支付的发展,揭示了企业"控制用户信息流以控制支付流,控制支付流以控制资金流;获得用户网络接入权胜过获得资本所有权,获得数据投入量胜过获得资金投入量"的新规则。大平台日益成为金融机构控制用户信息流、获得用户网络接入权的重要载体,在平台组合上加载信用有关数据流日益成为形成金融机构风险管理能力的重要生产资料。在互联网时代推进上海国际金融中心建设,既要继续重视金融机构集聚,更要注重鼓励企业赢得全国性用户网络接入权,加强平台组合,增强信用数据流。上海应依托自贸试验区推进互联网金融监管创新;牵头建立长三角征信联盟集团公司;搭建本地金融机构网聚平台。  相似文献
