基于Black-Scholes模型的沪深300股指期权定价研究

2013年11月8日,沪深300股指期权仿真交易开始在中国金融期货交易所运行,这意味着我国即将正式推出股指期权交易项目。基于Fischer Black、Myron Scholes和Robert Merton于1973年建立的Black-Scholes期权定价模型可以对沪深300股指期权定价进行模拟实证研究,计算出期限为1个月的沪深300股指期权合约的看涨期权价格和看跌期权价格,通过比较模拟交易数据,可以看出使用该定价模型可以较为准确地模拟出沪深300股指期权价格,从而显示出Black-Scholes期权定价模型对沪深300股指期权定价的有效性。     

连续贝塔、非连续贝塔与股票风险溢酬

本文利用高频数据将传统的CAPM贝塔分解为连续贝塔和非连续贝塔（跳跃贝塔和隔夜贝塔），并在此基础上进一步考虑正向市场和负向市场的非对称性，将跳跃贝塔又细分为正向跳跃贝塔和负向跳跃贝塔，以探讨不同类型系统性风险的特征差异及其所对应的风险溢酬。实证结果表明，个股对市场发生的非连续变动比连续变动更加敏感，投资者对市场发生的负向跳跃比正向跳跃反应更加强烈；中国股票市场上的系统性非连续风险溢酬（跳跃风险溢酬和隔夜风险溢酬）显著为正，但系统性连续风险并没有得到定价；其中，跳跃风险溢酬则主要来源于对系统性负向跳跃风险的补偿，而正向跳跃风险对股票横截面收益率没有显著的影响。     

A New Pearson-Type QMLE for Conditionally Heteroscedastic Models

This article proposes a novel Pearson-type quasi-maximum likelihood estimator (QMLE) of GARCH(p, q) models. Unlike the existing Gaussian QMLE, Laplacian QMLE, generalized non-Gaussian QMLE, or LAD estimator, our Pearsonian QMLE (PQMLE) captures not just the heavy-tailed but also the skewed innovations. Under strict stationarity and some weak moment conditions, the strong consistency and asymptotic normality of the PQMLE are obtained. With no further efforts, the PQMLE can be applied to other conditionally heteroscedastic models. A simulation study is carried out to assess the performance of the PQMLE. Two applications to four major stock indexes and two exchange rates further highlight the importance of our new method. Heavy-tailed and skewed innovations are often observed together in practice, and the PQMLE now gives us a systematic way to capture these two coexisting features.

Estimation of an Asymmetric Stochastic Volatility Model for Asset Returns

A stochastic volatility model may be estimated by a quasi-maximum likelihood procedure by transforming to a linear state-space form. The method is extended to handle correlation between the two disturbances in the model and applied to data on stock returns

Efficiency and stock performance of EU banks: Is there a relationship?

The purpose of this paper is to examine whether the stock performance of EU listed banks is related to their efficiency. Our sample consists of 171 banks operating in 15 EU markets over the period 2002–2006. First, we use stochastic frontier analysis to estimate the cost and profit efficiency of banks, while controlling for environmental factors. Then, we investigate if changes in profit and cost efficiency are reflected in changes in stock prices. Our results indicate that the change in profit efficiency has a positive and significant impact on stocks prices; however, there is no relationship between changes in cost efficiency and stock returns.     

内蒙古自治区资本存量K的估算

在分析经济增长过程中,不可避免的要涉及对资本存量K的估算。近年来,国内外一些学者对中国的资本存量进行了估测,但由于在方法和细节处理上的差异,从而造成估算的结果存在很大的差距。对于我国民族地区而言,由于统计数据的缺乏,因而对资本存量进行估算则更加困难。本文基于现有研究成果和相关统计资料,对内蒙古1952-2003年间资本存量进行了估算,以弥补相关文献空缺。     

上海股票市场分形特征的实证研究

以有效市场假说为基础的现代资本市场理论被越来越多的实践证明与现实情况不符,而分形理论则考虑到资本市场的复杂性和EMH的缺陷,以非线性范式为分析基础,解释了有效市场理论无法解释的许多市场现象,为更深入地分析资本市场提供了新的思路和方法。文章以上海股票市场为例,用分形理论对上海股市的分形特征进行了研究,其结果表明上海股票市场具有明显的分形特征。
