Prizes for basic research: Human capital,economic might and the shadow of history

We study the distribution of basic scientific research across countries and time, and explain the process that resulted in the United States becoming the undisputed leader in basic research. Our study is based on the records of scientific awards, and on the data of global economic trends. We investigate the degree to which scale/threshold effects account for the number of prizes won. We constructed a stylized model, predicting a non-linear relationship with lagged relative GDP as an important explanatory variable of a country’s share of prizes. Our empirical research findings find support for these predictions and the presence of a “winner-takes-all” effect.      

创业研究前沿理论发展动态

本文评述并探讨了经济学、社会心理学、社会文化理论、资源观、机会观和社会资本观等对创业研究的贡献、不足以及未来的研究方向。传统经济学理论无法解决创业现象从外部给均衡状态带来的冲击问题,奥地利学派虽然持动态系统观点,却无法模型化。社会心理学视角的创业研究结果相互矛盾,也没有产生多少有见地的观点。社会文化学观点讨论了社会文化环境对形成创业家个性与行为特征的影响,但同样没有取得什么重要的进展。资源观试图将资源观、创业能力和均衡联系在一起,但仍然不能解释创业机敏现象。文章作者认为,机会观点和社会资本观点摈弃均衡分析方法,转而考察创业过程中的创业个体和机会因素,为创业研究建构了一个全新的研究框架。     

磁流变传动装置理论分析与实验测试

在一定假设的基础上,建立了磁流变传动装置传递力矩的计算模型,对圆桶式和圆盘式结构磁流变传动装置的传递力矩及功率损失进行了比较分析,在此基础上确定了磁流变传动装置实验模型的结构参数,对该模型进行了实验测试。结果表明,通过调节电流的大小,可以实现转矩的智能控制。     

Seasoned Equity Issues in a Closely Held Market: Evidence from France

This paper examines seasoned equity offerings in France.Even though a rights offering is the primary flotation method, French companies are increasingly usingthe relatively expensive public offering method. We show that the market reaction to the announcementof seasoned equity issues is significantly negative for rights issues and insignificantly negative forpublic offerings. Our results suggest that the adverse selection effect is greater for rights issues thanfor public offerings, due to stronger underwriter certification for the public offerings. We find that theshare price effect is positively related to blockholders take-up renouncements for firms with priorconcentrated ownership. For these firms, the favourable ownership dispersion effect offsets the adverse selection effect.     

或有表外项目的分类和计量研究

2001～2002年，大量的重大会计丑闻曝光，这些问题暴露了公司治理、审计实务和财务报告中的薄弱环节，其中两个主要问题是表外项目的范围（包括特殊目的实体的使用）和股票发行者的财务报告是否透明地反映了表外项目的经济实质。本文主要对或有表外项目中投资的分娄和计量进行兮析，并提供了美国上市公司投资于其他实体的经验研究与发现，以期对今后的衍生金融工具的会计处理提供借鉴。

地方人大重大事项决定权工作机制探索

党的十八大对坚持和完善人民代表大会制度提出了新的更高要求,十八届三中全会作出的《中共中央关于全面深化改革若干重大问题的决定》,特别明确了人大重大事项决定权。鉴于目前地方人大及其常委会的决定权基本虚置的状况,本文探讨了地方人大重大事项决定权的涵义及工作机制,以期健全人大讨论、决定重大事项制度,推进人民代表大会制度理论和实践创新。     

Using Machine Learning for measuring democracy: A practitioners guide and a new updated dataset for 186 countries from 1919 to 2019

We provide a comprehensive overview of the literature on the measurement of democracy and present an extensive update of the Machine Learning indicator of Gründler and Krieger (2016). Four improvements are particularly notable: First, we produce a continuous and a dichotomous version of the Machine Learning democracy indicator. Second, we calculate intervals that reflect the degree of measurement uncertainty. Third, we refine the conceptualization of the Machine Learning Index. Finally, we significantly expand the data coverage by providing democracy indices for 186 countries in the period from 1919 to 2019.
