The use–make framework is employed to explain functional forms in production theory, including Cobb–Douglas and Leontief. Productivity and efficiency are interrelated by augmenting the framework with a linear program that determines the frontier output. 相似文献

This study examines why most derivatives markets that settle on the day following expiration choose the opening rather than the closing price as the final settlement price (FSP), whereas most markets that settle on the expiration day select an average rather than a single price as the FSP. Four exogenous changes in the Taiwan Futures Exchange settlement procedures provide an experimental basis for studying the settlement procedures’ impact on underlying assets. Greatest market efficiency is observed when the FSP is determined by a single rather than an average price and hypothesize that manipulation is prevented at the expense of market quality. 相似文献

This paper investigates the impact of international sanctions on energy efficiency by employing the panel fixed effect as well as average marginal effect from the Tobit model via data on 30 sanctioned states over the period 1996–2015 with international sanctions including unilateral, plurilateral, U.S., EU, UN, economic, and non-economic cases. Overall, we find that the imposition of unilateral sanctions leads to a 0.067% decrease in energy efficiency, but that of plurilateral sanctions positively contribute to energy efficiency in the case of the full sample of countries. Moreover, the imposition of UN sanctions has a greater decrease on energy efficiency in the target states than the 0.042% reduction of energy efficiency when the sanctionist is the U.S. For robustness, empirical results indicate that the imposition of plurilateral sanctions results in a drop of energy efficiency in Islamic countries, but an increase in non-Islamic countries, while there are also negative shocks induced by the imposition of EU sanctions on energy efficiency in Asian countries, but not for non-Asian countries. We also consider endogenous problems and dynamic specification by using indicator variables and System GMM. In summary, our empirical findings provide policy suggestions for those sanctioned countries about how to maintain energy efficiency when facing international sanctions. 相似文献

We propose a novel test to measure market efficiency while estimating the time-varying risk premiums of commodity futures, given that the prices are heteroscedastic. The risk premium is estimated using a state-space model with a Kalman filter modified for heteroscedasticity. Using 79 commodity futures traded on 16 exchanges during the period 2000–2014 and a Monte Carlo simulation, we demonstrate that the proposal produces robust results compared with conventional approaches. The global financial crisis has improved the efficiency and affected the trading volumes of commodity futures, but it has had no effect on the average or the volatility of risk premiums. 相似文献

鉴于信息不对称程度、制度实施成本和心理文化差异,文章提出"监管距离"假说,认为监管者和被监管者之间距离远近可以影响监管效果。实证分析中国沪深上市公司数据,文章从非对称风险视角出发,研讨了上市公司注册地距所在地中国证监会派出机构的地理距离对公司层面的股价崩盘风险的影响。我们发现,监管机构与上市公司总部的地理距离越远,该上市公司股价的崩盘风险越大。进一步分析发现,如果开通高铁或者上市公司所在地社会信任水平足够高,那么监管距离和崩盘风险的正相关关系是不显著的;如果监管负担严重或政府效率低下,那么监管距离和崩盘风险之间正相关关系更为显著。文章认为,地理距离具有监管信息效应、监管威慑效应和监管执行效应,能够影响股价崩盘风险。也就是说,"山高皇帝远"可以改变上市公司行为,提高金融监管效率不应忽视非正式制度的影响。 相似文献

AbstractJohn Roemer has argued in favour of rehabilitating Kanitanism as an antidote to the kind of utilitarian incentivisation theories associated with neoliberal economics. This article asks whether the ethical thought of Kant is in fact fit for purpose. Placing Kant in dialogue with other contemporary enlightenment thinkers, it also questions whether ‘solidarist’ social theories solve the problems Roemer associates with their ‘selfish’ competitors, and indeed whether the two approaches can be so neatly distinguished. 相似文献

对建筑企业进行环境行为效率评价是促进我国建筑行业健康可持续发展的重要手段。根据建筑行业特点及我国现有的企业环境信用标准,构建了建筑企业环境行为评价的投入产出指标体系,将改进的数据包络分析方法模型运用到企业环境行为效率评价领域,解决了现有企业评价研究主观性突出的问题,得出建筑企业评价分析方法。在此基础上对某代表性建筑企业2010—2017年环境行为数据进行了评价分析。分析结果表明该企业环境行为总体效率良好,但鉴于出现了奇数年和偶数年的效率波动情况,仍需提高环境行为效率。 相似文献

实现区域经济协调发展是当前我国在块集聚与点极化双重压力下面临的现实难题,长江经济带尤其是欠发达省份承接发达地区产业转移是解决该难题的必然路径选择。产业转移活动因区域主客体特征变量不同,呈现出典型的多发式转移和门槛转移特征,使得区域政策制定缺乏科学指导,陷入盲目拼政策红利的状态。结合效率模型及考虑熵权的经济社会发展协同度分析,测算了2004-2016长江经济带各省(市)年综合产业转移效率,并考察了门槛效应值及变化趋势。结果表明:在考察期内,长江经济带各省(市)产业转移效率提升较为明显,但不少省(市)存在不协调的阶段性平衡关系,且这种关系还未显露经济总量驱动下的协同发展能力。 相似文献

We commemorate the 50th anniversary of Ball and Brown [1968] by chronicling its impact on capital market research in accounting. We trace the evolution of various research paths that post–Ball and Brown [1968] researchers took as they sought to build on the foundation laid by Ball and Brown [1968] to create a body of research on the usefulness, timeliness, and other properties of accounting numbers. We discuss how those paths often link back to the groundwork laid and questions originally posed in Ball and Brown [1968]. 相似文献
