Environmental uncertainty, supply chain relationship quality and performance

Environmental uncertainty is a fact of life in today's supply chains. In this paper we develop a model of environmental uncertainty, supply chain (SC) relationship quality and SC performance. We use data from the electronics sector in Ireland to test our model. Our results provide mixed support for the model, with the moderating role of both demand and supply uncertainty being supported, but technological uncertainty not supported. We reflect on these findings and suggest a research agenda based on our results.

人力资本与经济增长关系研究——教育投资对经济增长的贡献自上市公司的经验证据

知识经济时代经济增长所依靠的已不仅是货币资本,更重要的是人力资本,货币资本的获得和财富的积累都是由人力资本推动的。人力资本是现代经济增长与发展的源泉和动力,增加人力资本投资,提高人力资源质量,已成为促进经济发展的重要手段。从我国经济增长的影响因素看,人力资本作为生产要素对经济增长具有决定作用,人力资本投资对我国经济增长具有战略意义。本文对经济增长理论及人力资本理论进行了介绍,并运用实证分析方法探讨了教育投资对经济增长的贡献。     

Factor taxation and labor supply in a dynamic one-sector growth model

This paper studies a class of AK-type growth models with factor income taxes, public capital stock and labor–leisure trade offs. While a higher capital tax rate reduces economic growth in the short run, the long-term growth effect is ambiguous and remains ambiguous even if the level of tax rate is larger than the degree of government externality. A higher labor income tax rate has ambiguous growth effects both in the short and long runs. However, if the intertemporal elasticity of substitution for labor supply is sufficiently small, a higher labor tax rate always lowers economic growth in the long run, despite the existence of productive government taxation.     

基于共同治理模式下的公司业绩评价指标体系探索

现代企业理论认为,企业是一系列合约的组合,其中最重要的是企业所有权合约,提高企业所有权安排效率的出路是资本所有者拥有剩余索取权与剩余控制权。在这种理论的基础上产生了“股东至上”理论,公司治理采用“股东至上模式”,与此相适应产生了相关的业绩评价体系。但是这种治理模式和业绩评价体系都存在着缺陷,为适应现代公司经营环境的变化,笔者认为,应该采用“共同治理模式”代替“股东至上模式”,并建立与之相适应的业绩评价体系。     

基于循环经济的环境财务分析指标体系构建

目前我国的经济增长与自然环境之间的矛盾十分突出,需要大力发展循环经济,而建立环境财务分析指标体系,有助于推动企业循环经济的发展。本文介绍了循环经济的基本理论,简要回顾了国内外关于循环经济的理论研究成果。在此基础上,分析了循环经济对传统财务分析指标的影响,主要体现在主体多元化、目标多元化和指标多样化上。并根据3R原则设计了若干环境财务分析指标,指出了这些指标在沃尔评分法中的应用。

How do economic policy uncertainty and geopolitical risk drive Bitcoin volatility?

We investigate how economic policy uncertainty (EPU) and geopolitical risks (GPR) impact Bitcoin volatility with respect to factors related to type and nationality of uncertainty, investigated period, relationship horizon and extreme conditions. Applying ARDL model and quantile regression for monthly data from August 2010 to September 2021, we reveal that June 2014 corresponds to a key date that marks a reversal in the investigated relationship. Furthermore, we show that the relationship between uncertainty and bitcoin volatility changes according to different factors. US uncertainty has short run effects on Bitcoin volatility, while China’s uncertainty has rather long run effects. Moreover, Bitcoin volatility responds in the same manner to US EPU and GPR, while, it responds differently to China's EPU and GPR. In extreme quantiles, we find that Bitcoin hedges against US EPU and GPR. Further, Bitcoin hedges against either individual or joint effects of US uncertainty, but not both.     

Does economic policy uncertainty drive the dynamic spillover among traditional currencies and cryptocurrencies? The role of the COVID-19 pandemic

The paper examines the dynamic spillover among traditional currencies and cryptocurrencies before and during the COVID-19 pandemic and investigates whether economic policy uncertainty (EPU) impacts this spillover. Based on the TVP-VAR approach, we find evidence of spillover effects among currencies, which increased widely during the pandemic. In addition, results suggest that almost all cryptocurrencies remain as “safe-haven” tools against market uncertainty during the COVID-19 period. Moreover, comparative analysis shows that the total connectedness for cryptocurrencies is lower than for traditional currencies during the crisis. Further analysis using quantile regression suggests that EPU exerts an impact on the total and the net spillovers with different degrees across currencies and this impact is affected by the health crisis. Our findings have important policy implications for policymakers, investors, and international traders.
