大股东终极现金流量权与债务融资的关系研究——来自中国上市公司的经验证据

以中国上市公司为研究对象,考察第一大股东终极持有的现金流量权比例如何影响公司的债务融资决策,从而揭示了负债在大股东治理中的激励约束作用.实证结果表明,公司的债务水平与非国有大股东的终极现金流量权比例呈现一种非线性的倒"U"型关系,而与国有大股东的终极现金流量权比例则呈现一种非线性的正"U"型关系,说明负债的股权非稀释性和破产机制能够有效约束非国有大股东的行为,但并不能约束国有大股东的行为.     

Wheat breeding,productivity and slow variety change: evidence from the Punjab of India after the Green Revolution*

Variety change and genetic diversity are important means of combating crop losses from pests and diseases in modern agricultural systems. Since the Green Revolution, genetic diversity among wheat varieties released in India has increased but variety change on farms continues to be slow. In this article, we define and summarise indices of variety change and genetic diversity for the wheat varieties released and grown in Indian Punjab during the post‐Green Revolution period. We evaluate the effect of each index on technical efficiency with a Cobb‐Douglas yield model after testing for exogeneity. Findings support the hypothesis that slow variety change has offset the positive productivity effects of diversifying the genetic base in wheat breeding during the post‐Green Revolution period. Policies that speed the rate of variety change and contribute to a more equitable spatial distribution of modern varieties could support wheat productivity in the Punjab of India, reinforcing plant breeding successes.     

疫情冲击下全球股市的风险溢出效应研究

本文通过构建全球股市风险溢出网络,测度疫情期间全球股市风险溢出强度,研究各国股市风险的传递方向及溢出机制;通过与2008年金融危机的横向比较以及全样本纵向分析,探究不同阶段全球股市风险溢出效应的差异.研究发现:(1)疫情期间全球股市风险总溢出强度先上升后下降,其强度明显高于2008年金融危机与全样本均值.(2)不同时期全球股市风险溢出中心存在差异,中国是全球股市的主要风险接受国.金融危机时期,美国是全球股市单一的风险溢出中心;疫情期间,疫情严重的欧洲国家成为全球股市的风险溢出中心.     

数据治理的国际经验及对我国完善征信数据跨境管理的启示

2021年8月20日,《中华人民共和国个人信息保护法》由第十三届全国人大常委会第三十次会议正式通过,翻开了我国个人信息立法保护的新篇章,也是全球数据治理发展的重大里程碑.随着经济全球化进程的持续推进,各类生产要素在全球范围内自由流动,数据安全治理已成为事关国家安全、经济社会发展、信息主体权益的重大问题.在开放发展的时代背景下,外资征信机构陆续进入我国展业,征信数据跨境流动的需求日益增长,而我国数据跨境流动管理体系有待进一步完善,应加强征信数据跨境流动监管,以规范征信数据传输行为.通过梳理欧美等主要国家和地区数据治理模式,分析我国数据跨境流动的相关规定和发展现状,在此基础上,从完善数据保护相关法律制度、制定征信数据跨境安全评估方案、强化对数据跨境传输的监管、分步稳妥推进征信数据跨境流动、积极参与数据跨境流动的国际交流与合作等方面提出政策建议.     

Unravelling the design process of business models from linear to circular: An empirical investigation

In the last years, circular economy has represented one of the most-debated topics in management research. Although the understanding of this industrial paradigm has significantly improved over the last decade, a number of important research questions still remain unanswered. Among them, the design process of business model through which established firms evolve from being linear to circular deserves further investigation. Existing research still falls short to investigate how companies design the dimensions of value creation, value transfer, and value capture of their business models to launch circular products into the market. By leveraging a multiple case study analysis of four companies in the paper and beverage industries that have launched six circular products, the paper examines the process that these companies have followed to face the transition toward a circular business model. The paper contributes to the research field in the intersection between new product development and circular business models, by showing that the process toward a circular business model occurs along three major phases, that is, idea generation, product development, and commercialization. In each phase, companies implement peculiar managerial practices for launching circular products into the market, which typically address all the dimensions of the business model and follows a recurrent path over time.     

Horizontal vs. vertical transmission of fertility preferences

I study the cultural transmission of fertility preferences among second-generation immigrant women observed in U.S. Censuses from 1910 to 1970. As hypothesized by Bisin and Verdier (2001), the transmission of preferences can be “vertical” or “horizontal”. Using a unique source documenting the variation in fertility behavior in Europe before and after the first demographic transition (1830–1970), I unpack the influence of parents (measured by source-country fertility at the time of departure from Europe) versus the influence of peers from the same source-country (measured by fertility of the same-age cohorts living in the source-country and transmitted by same-age recent immigrants). I find that the transmission mechanism is crucially affected by the number of foreign-born immigrant peers living in the same MSA. On one hand, the “vertical” channel of transmission is stronger in places where there are few newly arrived foreign-born immigrant couples from the same source-countries. On the other hand, the “horizontal” channel prevails in MSA’s densely populated by recently arrived immigrants from the same source-countries of second-generation ones.
