R&D,public innovation policy,and productivity: The case of danish manufacturing

The purpose of this paper is to investigate the relationship between private R&D, public innovation support transferred to the private sector, and productivity in Danish manufacturing. Two main conclusions are established. First, public innovation support has a positive and significant effect on private R&D expenditures with an estimated elasticity of 0.062. Second, the indirect effect on productivity from public innovation support is reflected in a positive point estimate which is found to be robust to different specifications of R&D capital.     

我国承销商利用分析师报告托市了吗?

学术界对于我国IPO市场是否存在承销商托市行为一直存在争议。本文通过搜集新股上市一年之内的分析师报告数据,系统考察了我国承销商利用分析师报告进行托市的行为特征,以及投资者对于承销商分析师具有托市性质报告的市场反应。结果发现:(1)承销商会利用乐观、但偏颇的分析师报告为市场表现不佳的新股进行托市,但这一现象在新股上市90天后消失;(2)声誉机制在新股解禁期后才能有效约束承销商利用分析师报告托市的利益冲突行为;(3)市场投资者总体上能够识别承销商的托市意图,并对承销商分析师报告的系统偏误进行自我调整。本文的研究不仅为我国承销商是否存在托市行为提供了新的直接性经验证据,而且有助于市场各方洞悉分析师报告背后的利益冲突,同时也为监管部门出台相关的规范政策提供了新的决策参考。     

产军协同、政府科技支持与技术创新效率研究

运用空间数据分析方法,检验产军协同、政府科技支持与技术创新效率在我国省域间的分布格局。研究表明,三者均存在显著的正向空间相关性,即正向空间溢出效应,并且在不同地区形成局部空间集聚,存在高低非均衡的“俱乐部”现象。基于空间误差模型和空间滞后模型,实证检验产军协同、政府科技支持对技术创新效率的影响。结果发现,从全国和分地区看,产军协同、政府科技支持均能够显著促进技术创新效率提升,并且二者存在显著的交互作用,能够发挥彼此间的互补效应,进一步促进技术创新效率提升;不同地区产军协同、政府科技支持对技术创新效率的影响程度存在较大差异,西部地区产军协同、政府科技支持对技术创新效率的促进作用比东部和中部地区显著。     

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.     

On structural change,the social stress of a farming population,and the political economy of farm support

A rationale for providing support to the farm sector in the course of economic development and structural change is a growing gap between the incomes of non‐agricultural workers and the incomes of farmers. Drawing on a model that enables us to analyze the level of social stress experienced by farmers as employment shifts from the farm sector to other sectors, we find that even without an increasing gap between the incomes of non‐agricultural workers and the incomes of farmers, support to farmers might be needed/can be justified. This result arises because under well‐specified conditions, when the size of the farm population decreases, those who remain in farming experience increasing aggregate social stress. The increase is nonlinear: it is modest when the outflow from the farm sector is relatively small or when it is large, and it becomes more significant when the outflow is moderate. This finding can inform policymakers who seek to alleviate the social stress of the farming population as to the timing and intensity of that intervention.     

企业80后知识型员工工作倦怠与离职倾向之间的关系研究——以组织支持感为调节变量

文章以企业80后知识型员工为研究对象,研究其工作倦怠、组织支持感与离职倾向之间的关系.首先采用统计软件SPSS17.0进行描述性统计分析、相关分析、回归分析,最后采用层次回归的分析方法考察组织支持感的调节作用.通过实证研究得出:工作倦怠与离职倾向显著正相关;组织支持感与离职倾向显著负相关;企业80后知识型员工工作倦怠对其离职倾向具有较好的正向预测作用;企业80知识型后员工感知到的组织支持感对其离职倾向具有较好的负向预测作用;组织支持感在工作倦怠和离职倾向之间起到了明显的调节作用.     

对保险业支持新型城镇化建设途径的思考

我国城镇化率正在逐年攀升,在2012年该比例已达52.57％.伴随着城镇化的进一步发展,城镇化建设所需资金等资源进一步紧缺,单靠政府支撑城镇化的局面已经不再适应高速发展的城镇化.而我国保险业在不断扩大自身业务,进军地产、信托等产品后,资金实力和其他综合管理能力进一步强化,为支持我国城镇化建设提供了契机.本文将探讨目前我国城镇化建设过程中遇到的困难和挑战以及保险业应该如何抓住这些机遇,支持新型城镇化的建设.

Do your tax problems make tax evasion seem more justifiable? Evidence from a survey experiment

Taxpayers often view tax rules and filing processes as complicated. I study whether the perceived tax uncertainty among peers makes tax evasion more acceptable among the general public. I find strong supportive evidence for this hypothesis using a survey experiment and a large representative sample of the German population. Providing randomized information that others are uncertain about how to file their taxable income decreases individual support for tax compliance. This suggests that subjects judge tax evasion less harshly in response to this peer information. Studying related heterogeneous treatment effects, I find that both older and left-wing subjects are more responsive to tax uncertainty of others. Less harsh views on evasion are persistent for very high compliance levels in a follow-up survey.
