We explore whether the market variance risk premium (VRP) can be predicted. We measure VRP by distinguishing the investment horizon from the variance swap’s maturity. We extract VRP from actual S&P 500 variance swap quotes and we test four classes of predictive models. We find that the best performing model is the one that conditions on trading activity. This relation is also economically significant. Volatility trading strategies which condition on trading activity outperform popular benchmark strategies, even once we consider transaction costs. Our finding implies that broker dealers command a greater VRP to continue holding short positions in index options in the case where trading conditions deteriorate.  相似文献

Are firm entry and fixed exporting costs relevant for understanding the international transmission of business cycles? We revisit this question using a model that includes entry, selection to exporting activity, physical capital accumulation and endogenous labor supply. We determine that once the stochastic process for exogenous productivity is calibrated to consider the endogenous dynamics in TFP created by the number of firms and the time series volatility of entry is calibrated to the data, our model yields minimal departures from the Backus et al. (1992) benchmark. The richer model shares all of the successes of the previous model in terms of the volatilities of aggregate quantities, as well as its failures, in terms of replicating patterns of international co-movement and the volatility of international relative prices.  相似文献

The author provides an economic analysis of tradable pollution permits by clarifying the derivation of permit supply and demand relationships and connecting those concepts to permit trading for the case of two polluters. Using the standard comparison of costs and benefits, he makes the marginal cost of emission reduction of a typical polluter the basis of the derivation of its permit supply and demand schedules. Developing these relationships for both polluters allows the creation of market schedules for permit supply and demand. He demonstrates equilibrium in the market for permits and the corresponding trading of permits. He discusses the satisfaction of the equi-marginal principle, which ensures that pollution reduction is achieved efficiently. The author concludes by considering the consequences of the presence of a third polluter in the market for permits.  相似文献

在现代教育中,作为以卓越为目标追求的学校,将个人素质或学习能力作为招收学生的一个决定性因素.考试是个人素质与学习能力考核的替代性安排,这种制度安排既节约交易费用,同时又产生社会资源浪费.资源浪费的表现形式体现为提高考试分数,而不是在提高素质上加大投入,即应试教育的产生和壮大.学校招生制度的变革能够在一定程度上减少这种浪费.  相似文献

Australian directors who incur debts while their companies are insolvent can be pursued by the corporate regulator for compensation when their companies fail. Under the Australian insolvent trading laws, directors no longer experience ‘true’ limited liability, and as expected, they adjust their behaviour as a result. Identifying director's rational behaviour in an insolvent trading world is difficult as there are no formal economic models of director decision-making under Australian current corporate law. In this paper, we develop such a model primarily for private companies. We incorporate the threat of insolvent trading as well as director's tactical use of voluntary administration to avoid insolvent trading litigation. We show that neither a combination of insolvent trading or voluntary administration can simultaneously ensure creditors-best outcomes, eliminate insolvent trading and reduce director underinvestment.  相似文献

异常利润汇出的方式主要有通过构造利润分配决议、虚构利润等方式实现超额利润汇出和利用跨部门监管薄弱环节违规汇出。对异常利润汇出排查的传统方式主要基于服务贸易外汇监管系统的定期预警指标,成本高企且效率低下。人民银行济南分行在分析异常的利润汇出行为特点及资金流动路径的基础上,提出了将指向性强的筛查指标和"交易圈"分析法相结合的创新性核查方法,有效提升了核查线索的精准度及发现异常违规行为效率。  相似文献

"双碳"目标展现了中国作为负责任的大国,对建设人类命运共同体的担当,碳排放权交易是实现这一目标的重要途径,但其对地区经济与环境的双重影响依然有待检验。结合1997—2017年中国省级数据,采用包含非期望产出的SBM-DEA模型测度地区绿色经济效率,以碳排放权交易试点为准自然实验,运用合成控制法评估试点政策对地区绿色经济效率的影响,并采用空间计量模型从损益偏离视角展开机制检验。研究发现:碳排放权交易试点政策能够显著提升地区经济效率,运用双重差分模型和PSM-DID进行稳健性检验后,基本结论依然可靠。缓解"收益在外,污染在内"的损益偏离现象,是碳排放权交易试点机制提升绿色经济效率的有效途径。随后提出通过进一步完善碳排放权交易市场机制,进而推动我国绿色发展的相关政策启示。  相似文献

Carbon market, which is capable of scientific quantifying and marked-based pricing of carbon emission, is an important way for countries to achieve the target of carbon emission reduction. The global carbon market, after more than ten years of development, has developed a mature mechanism. China started the trial of carbon market in 2011. After ten years of exploration, the national carbon trading market was officially launched in mid-July 2021. Against the backdrop of carbon neutrality, the national carbon market will shoulder a greater mission of carbon emission reduction and speed up its financialization and internationalization. However, it should take a dialectical attitude toward the opportunities and risks of carbon market financialization. In the future, China can promote the development of carbon market through efforts to develop market participants, clarify the attributes of carbon finance, prevent potential risks of carbon finance, improve the connection mechanism with the international carbon market, and innovate carbon finance services.  相似文献

日本和欧美等发达国家已经建立了较为成熟的碳交易市场,并通过碳交易取得了显著的环境和经济效益。我国国内的碳交易市场机制十分落后,还没有一个成熟的国际碳交易市场。作为能源消耗大省,辽宁省的碳减排压力指数全国位列第六,辽宁省低碳经济建设任重道远,务实发展碳交易市场是发展低碳经济的首要任务。本文首先详细论述了辽宁省发展碳交易市场的重要意义,指出碳交易市场对辽宁经济建设、财政收入、环境改善及增强企业竞争力都具有较大的推动力。通过对辽宁省碳交易市场发展现状的分析,发现辽宁省碳交易市场建设中存在的问题主要集中在CDM项目、碳交易所建设及自愿减排市场上。根据辽宁省发展阶段的特点,提出了推进碳交易市场建设的相关建议。  相似文献

中国电力行业碳排放配额分配——基于排放绩效   总被引:2,自引:1,他引:1  
阐述了我国二氧化碳排放现状;预测了2015年、2020年我国二氧化碳的允许排放量,测定出电力行业的二氧化碳排放控制目标,并将其分解到不同容量等级的发电机组中;基于排放绩效方法,对2015年、2020年不同火电厂的碳排放配额进行了分配;最后给出在我国推广排放绩效机制所需的政策支持。研究结果表明,利用排放绩效机制能有效分配碳排放配额,控制二氧化碳排放量,是电力行业实施碳减排的一种有效机制。  相似文献
