Implications of variant efficiency measures for policy evaluations in UK higher education

Policy goals in UK higher education encourage the publicly funded universities to become more-specialised and larger in size without compromising output quality. Efficiency gains are expected to flow from this increased specialisation in accordance with universities’ comparative research and teaching strengths. Mergers to reap further gains from economies of scale are also being actively encouraged. Given this scenario, the paper investigates whether best-practice efficiency measurement based on data envelopment analysis (DEA) provides empirical support for the current policy goals. It also assesses whether such support is dependent on the specific type of efficiency measure used in the DEA modelling. This assessment finds that a selection of (nine) commonly used, variant efficiency measures generally support the current policy goals. The paper also uses the principal-agent framework to explore the issues involved in using computed DEA-based efficiency scores for policy evaluations and possible funding guidance in UK higher education. This highlights empirically how policy-makers and universities can have very different preferences about which efficiency measure is to be used for policy evaluations and possible funding guidance.     

供应链环境下的成本管理研究

本文就供应链环境下成本管理问题展开研究。文章认为在供应链环境中,管理者面临着更加复杂的成本问题,这就要求我们整合传统的成本管理框架,拓展成本管理的视野。为此,本文阐述了基于供应链模式下的成本管理目标、影响成本管理维度、成本管理方法和成本管理组织机构设立等等方面内容。说明成本管理目标是提升整个供应链的竞争力;影响成本管理维度的因素分别为产品、关系和资源;在供应链环境下作业成本法和链式目标成本是常常采用的成本方法。其次说明了柔性管理团队是供应链模式下成本管理目标实现的组织保证。

企业集团投资决策方法的发展趋势

在针对决策方法选择对企业集团投资的重要性上,本文主要阐述了企业集团投资决策方法的发展趋势。企业集团投资决策过程中所遵循的决策准则表现为多元化和核心性,更加突出了决策方法的战略性要求;而未来的企业集团投资决策方法,其主流趋势仍旧是以项目评价为基础。不以现金流量为基础的评价方法完善了传统投资决策方法,而且定性与定量方法相结合的趋势将企业集团投资管理推向了更高的发展阶段,使投资决策方法逐渐地向模拟化发展。

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.     

Understanding resource deployment efficiency for ESG and financial performance: A DEA approach

COVID-19 has stimulated additional research interest on economic sustainability and ESG in both academia and industry. This study adopts a DEA approach to examine the efficiency of achieving ESG targets and their relationships with financial performance. Using MSCI ESG data from 2015 to 2019 on 1108 Chinese firms, we examine the ESG proportional and pillar mix efficiencies. The dominant strategies for our sampled firms are to improve overall ESG performance by enhancing the E and S pillars through sacrificing G’s performance. The second result shows a positive relationship between proportional efficiency and financial performance while a mixed relationship between pillar mix efficiency and financial performance. However, for the technology sector, there exists some trade-offs between ESG performance and financial performance. Specifically, relative to non-technology firms, improving proportional and pillar mix efficiencies for technology firms could result in some sacrifice in stock valuation.
