在多层次资本市场的大发展趋势下,建立有效的衍生品-现货互补对冲机制是完善金融市场的基本要求。期货-现货体系为投资者提供套期保值风险对冲功能对期货与现货合约的紧密联系程度提出非常高的要求,这不仅应体现在价格上,更应微观的体现在交易过程的订单流动性中。若在任何情形下,订单流动性的趋同能够立刻反应在两类金融证券中,那么异常的基差风险就很难发生,股指期货与现货之间将存在健康的"遛狗效应"。本文以期货现货合...
本文使用实物期权方法研究中国目前实施的风电固定上网电价政策。首先说明风电项目投资的实物期权原理,并建立风电固定上网电价政策实物期权模型。然后,从理论上证明了风电最优投资电价与上网电价波动率成正比(固定上网电价理论依据,即政府为了最大限度激励投资者,使得上网电价波动率等于0);最优投资电价与上网电价期望增长率成正比(固定上网电价调整理论依据)。最后,选取河北张北油篓沟元山子风电场工程项目进行实证分析...
股市收益率高阶矩风险的产生机制检验
高阶矩风险 波动率反馈 限制卖空 条件密度
2016/6/2
通过对现有理论文献的梳理,提炼了五个较为典型的关于高阶矩风险产生机制的理论假设。然后基于时变高阶矩建模思想,将这五个假设统一于同一个计量框架,并进行综合地实证检验,以期发掘具有"占优"作用的理论解释。以沪深股市收益率为样本研究发现,在这五个假设中,仅"波动率反馈"效应和"利空信息揭示"效应获得显著的实证支持。进一步分析指出,这两种效应会同时引起偏度和峰度风险,因而是高阶矩风险的主要产生机制。这一结...
基于MSVAR模型的有色金属价格波动影响因素的非线性效应研究
有色金属 价格波动 MSVAR模型 区制转换
2016/6/2
由于新兴市场需求增长和指数化投资同时出现在金属期货市场上,且供需因素与金融因素相互作用使得有色金属价格形成机制更为复杂,呈现出非线性、动态性以及结构异化等特征。基于此背景,本文提炼供需因素与金融因素影响有色金属价格波动的作用机理,选取2000年2月至2014年3月的月度数据,并构建MSVAR模型以铜为例展开实证分析。结果表明:铜价波动存在显著的区制转换特征,即膨胀期、平稳期、低迷期三种状态;三种状...
碳限额与交易政策下考虑绿色技术投入的定价策略研究
碳交易 绿色技术投入 定价策略
2016/6/2
从微观低碳经济的角度出发,建立了企业在碳限额政策,碳限额与交易政策以及在碳限额与交易政策下进行绿色技术投入三种情形下的定价策略模型。研究结果表明:(1)在碳限额政策下,企业的最优定价和期望利润均不会大于在无限额下的最优定价和期望利润。(2)在碳限额与交易政策下的最优定价低于无限额下的最优定价,高于碳限额下的最优定价。此时,企业的最优定价主要取决于限额时的产品边际利润大小,企业的期望利润主要取决于政...
