土地流转：弱转入土地意愿的博弈分析

[目的]我国土地制度的施行使得农户拥有较多小块土地,家庭农场实现连片规模经营的前提是获得规模连片土地,家庭农场与农户进行土地流转协商时,农户将土地流转给家庭农场的意愿如何值得探讨。因此本文研究目的是对家庭农场实现规模连片生产提出建议,期望家庭农场实现规模化经营。[方法]博弈分析法。[结果]家庭农场存在从农户手中转入土地困难,转入土地意愿不强的现象,家庭农场弱转入土地意愿的根源在于土地租金过低、农户转出土地净利润过低、实际转入土地意愿过低。[结论]由此文章提出了3点建议:(1)尝试"确权不确地,确地不确人"的确权政策(2)创建农村土地经营权流转信息平台,建立农村土地流转交易所(3)工商资本下乡租田的做法需谨慎。     

基于计划行为理论的农户耕地转入和转出意愿对比研究

［目的］农民耕地原子化程度不断加深，现行的家庭联产承包责任制已不能适应农村商品化和市场化的进程，严重制约了农村地区的经济发展。对山东部分农村地区农户进行耕地转入和转出意愿对比分析，以促进农村地区耕地流转提出可行性的建议，以期加速农村地区市场化进程，实现经济快速发展。［方法］以计划行为理论为基础，文章以行为态度、主观规范、感知行为控制3个潜在变量， 11个可测变量构建农户耕地转出和转入意愿模型，以山东省6个地区549户农户的实地调查数据为样本，利用结构方程模型对农户耕地流转意愿进行实证分析。［结果］行为态度和知觉行为控制对农户耕地转入和转出意愿都具有显著影响，且标准化路径系数都为正； 主观态度对耕地转入意愿具有显著性影响，其标准化路径系数为负，对转出意愿的标准化系数为正； 11个可测变量分别对相应的潜在变量都有显著性影响。［结论］行为态度对农户耕地转入和转出的影响效果不同，转入耕地的农户主要从耕地固有价值出发，而转出耕地的农户主要从经济理性考虑； 主观规范中4个可观测变量对农户耕地转出和转入的影响具有一致性； 知觉行为控制中农户的契约意识对耕地转出重要性大于耕地转入。

Challenges in the Portuguese textile and clothing industry: a fight for survival

The Portuguese textile and clothing industry thrived after 1960, when Portugal joined the European Free Trade Association, and it has been an important industry in Portugal in terms of value added, employment, and exports. Nevertheless, the industry has experienced significant challenges with the final integration of the apparel and textile industry into GATT on 1 January 2005, as well as the admission of relatively low-wage Bulgaria and Romania into the European Union in 2007. This paper describes recent trends in the industry between 1995 and 2016, including a substantial decrease in output after 2005 and recovery in recent years. In addition, a translog cost function is used to examine the existence of economies of scale, the relationships among inputs, and the effects of the 2005 GATT entry on the industry’s costs. The findings include strong evidence of economies of scale, consistent with the many small and mid-sized enterprises in the Portuguese textile and clothing industry. The results are also consistent with capital and labour being complementary inputs, while other input pairs are substitutes. The entry into GATT may have had a negative impact on cost, though the evidence for that effect is weak.     

风险传染的信息识别——基于网络借贷市场的实证

基于清华大学金融科技研究院互联网金融研究中心网络借贷平台数据库与网贷之家相关平台统计数据,通过构建Logit模型与Cox比例风险回归模型来研究2015年12月e租宝事件和2018年6月备案延期后的“爆雷”现象,本文着重考察投资者是否具备根据信息披露程度识别问题平台和正常平台的能力。本文发现,第一,信息披露程度是影响平台风险的重要因素:信息披露程度越高的平台,其运营时间越长,出现问题的可能性越低。第二,信息披露程度越高的平台对抗风险的能力越强。风险传染期内,信息披露程度较高的平台,其成交量受市场负面情绪的影响较小。上述两点表明,总体而言,投资者重视平台披露的信息,并具备一定的信息识别能力。最后本研究也发现,上述两次风险事件期出现的问题平台是市场出清所需,它们和正常运营平台存在较大差异,尚无证据表明大量正常平台被拖累成问题平台。     

The role of relationship quality in raising organizational change acceptance: The case of the Greek hotel industry

This study examines whether the quality of an employee's relationships, within the context of the hotel industry, has an influence on their behavioral intention towards organizational change. The researchers suggest that the quality of relationships is an important element of an individual's social capital and can be evaluated using five key dimensions: the extent to which relationships are tangible, responsive and reliable, as well as the extent to which they offer empathy and assurance. Furthermore, this research examines whether organizational commitment and job satisfaction have an effect on the association between relationship quality and an individual's behavioral intention towards organizational change. The data collected from a sample of 100 hotel employees in Thessaloniki, Greece, show that relationship quality has a positive association with an individual's behavioral intention towards change. Additional results highlight the roles of job satisfaction and organizational commitment as mediating variables. Managerial implications relevant to the findings and pathways for further research are also discussed.     

STOCK‐BOND CO‐MOVEMENTS AND FLIGHT‐TO‐QUALITY IN G7 COUNTRIES: A TIME‐FREQUENCY ANALYSIS

This paper examines co‐movement between stock returns and changes in 10‐year government bond yields as well as flight‐to‐quality behaviour in G7 countries. We conduct the wavelet squared coherence analysis to explore the dynamics in both time and frequency domain. Our results provide evidence of positive co‐movements, which vary over time and across investment horizon. The higher co‐movement is found to be more concentrated in the lower frequency bands. We further analyse the dynamic nature of the scale‐dependent wavelet correlations and find that the correlations are highly volatile and significantly increase across different time scales during the episodes of equity market turbulence. The increase in correlations reflects flights from stocks to safer bond investments as a result of dramatic changes in investor sentiment and risk aversion at times of market stress.     

Welfare Policy and Precarious Lives: “Welfare Reform” Revisited

Abstract:

Although welfare reform has not been one of the most highly visible policy agendas for the Trump administration, restricting access to public assistance programs has been a part of proposals and actions in a number of areas. The Trump administration’s overall approach to welfare reform was articulated formally in 2018 in an Executive Order and a Council of Economic Advisers Report. To provide some context for a discussion of these two documents, the article begins with a discussion of the different meanings of “welfare reform” identified in institutionalist literature, and a brief overview of some important findings on the impacts of the 1996 welfare reform. It then highlights some key aspects of the Trump administration’s approach to welfare reform and responses from the poverty research and advocacy community.     

John R. Commons and Government as Employer of Last Resort: Three Paths to a Progressive Right to Work

Abstract:

Today in the United States, a number of congressional Democrats endorse proposals that would establish a job guarantee for all Americans seeking work. Arguments for such a policy can be traced back at least to the work of John R. Commons, one of the first institutional economists. This article demonstrates that there are actually three arguments in Commons’s scholarship that provide a case for government to hire the unemployed by serving as employer of last resort. These arguments, each highlighted at a different point in Commons’s career, can be viewed in turn as legal, financial, and historical paths to public provision of work for the jobless—government employment that Commons considered part of “the right to work.” The article traces each path, highlighting insight that remains relevant and calling for greater attention to Common’s writings as a way to reclaim the right to work as a progressive cause.
