存款保险定价模型与中国模式选择

本文引进了存款保险定价的期权定价模型和预期损失模型,针对中国现阶段的商业银行经营状况,在预期损失模型的基础上,真实测算了存款保险费率,并建设性地从中国国情出发提出了存款保险费率的基本模式和基于混合方法的拓展模式。最后评价了本文所涉及的存款保险定价模型,并基于实务的角度提出了存款保险费率确定机制。     

期权定价理论在存款保险定价问题中的应用

存款保险制度的核心问题是存款保险费率的确定。本文在深入分析存款保险自身的特点的基础上,应用Black-scholes期权定价模型对存款保险价格问题进行了探讨。并以一个具体的实例对这一应用进行实证分析。分析结果表明,这一应用是科学的,可行的。从而可以为各国存款保险制度的正确确立提供了一定的依据。     

存款保险定价模型研究

存款保险作为三大金融安全之一,在美国二十世纪三十年代首次建立以来,在保护存款人利益的同时,防范系统性金融危机的发生。我国于2015年5月1日正式实施《存款保险条例》,标志着我国从政府担保的隐性存款保险制度向显性存款保险制度的转变。存款保险的核心是存款保险定价,而合理的定价模型至关重要。本文从存款保险的理论定价模型和各国采用的定价模型入手,分析各方法的优缺点,通过比较分析提出适合我国未来存款保险定价模型的思路。     

我国银行存款保险定价研究——基于我国16家上市银行的实证分析

建立存款保险制度是我国"十二五"规划金融改革中提出的重要举措,也符合我国完善金融体系和金融市场的制度建设中的需要,这对我国未来金融发展具有重大的意义。而存款保险制度建立的一个核心问题是存款保险的定价,本文通过分析比较三种存款保险定价模型,采用考虑了监管者宽容的RV模型,运用2011年我国16家上市银行的数据得出我国更适合风险费率及各个银行适用的存款保险费率,而不适合单一保险费率。     

对期权和期权定价模型(BSPM)的探析

期权及其期权定价模型一直都是金融学研究的重点领域,从它产生发展到现在,在金融学中占着举足轻重的地位.特别是期权定价模型(BSPM)更是得到了广泛的运用,本文就是对期权和该模型的相关理论知识进行了梳理,之后对期权定价模型(BSPM)在我国的运用进行了评价.     

随机支付红利的跳-扩散模型下幂期权的定价

假设股票价格服从Poisson跳-扩散过程,且随机时间支付红利,建立股票价格行为模型。应用保险精算法给出欧式看涨和看跌幂期权的定价公式,推广了Merton关于期权定价的结果。     

期权定价思维和保险精算思维的关联分析

论述了期权定价与保险精算的概念界定,探讨了以及两者之间的联系及相似点,将期权定价思维流程借鉴到保险定价思维的建构之中,并围绕着有关话题展开相关论述。     

期权模型在财产保险偿付能力研究中的应用

期权模型已广泛应用于金融保险业。本文将期权定价模型运用于财产保险的偿付能力分析。在保险被视为公司的负债且保险的需求函数与偿付能力不足风险成反比的假设下,可通过选择偿付能力不足风险的水平来实现保险人的利润最大化。     

中国商品期货期权定价及实证研究

本文是在我国没有期权交易实践的情况下进行的超前研究。目的是寻找中国商品期货期权定价特点，为制定各项交易制度提供实证支持。本研究首次运用郑州商品交易所期权交易模拟数据确定基础资产价格与期权价格之间的因果关系，并对希腊字母（风险参数）进行详尽分析和研究，为期权上市后的风险控制奠定基础。研究表明，期权定价模型实用、可行，为未来上市期权交易提供了佐证。     

认股权证定价理论探讨

认股权证在性质上也是一种期权,但并不是一种单纯的期权,其定价要比普通期权复杂。期权定价理论不仅支撑着期权市场的发展,同时推动了整个金融衍生市场的发展。本文回顾了经典的期权定价理论及欧式期权定价模型。本文还在Black-Scholes模型的基础上,通过改变B-S模型的基本假设,给出了几种基本的修正模型及定价公式。     

Revisiting the valuation of deposit insurance

This study proposes a framework for pricing deposit insurance that evaluates the effect of depositor preference laws and the issuance of contingent capital bonds. Four main findings emerge from this study. First, traditional option pricing models of deposit insurance overestimate insurance premiums. Second, only large issuances of contingent capital bonds decrease deposit insurance premiums under depositor preference. Third, the issuance of contingent capital bonds can partially offset banks' excessive risk-taking caused by regulatory forbearance. Finally, although large banks have implied too-big-to-fail risks, the deposit insurer's costs from large banks are not nearly as high as reported in previous studies.     

二叉树方法在风险投资决策中的应用

在过去的20年中,许多学者开始应用期权定价方法去估计实物资产价值,并在此基础上对公司的最优投资决策进行了大量研究。利用二叉树方法,通过对一个欧式期权与一个美式期权构成的复合期权进行定价,完成对风险投资问题的估价。主要有两个方面的内容:用实例说明怎样用二叉树方法对投资期权进行估价;把从期权模型获得的价值与用净现值方法得到的价值相关联,从而获得风险投资的最终的价值。     

THE EARLY EXERCISE PREMIUM REPRESENTATION OF FOREIGN MARKET AMERICAN OPTIONS1

The note deals with the pricing of American options related to foreign market equities. the form of the early exercise premium representation of the American option's price in a stochastic interest rate economy is established. Subsequently, the American fixed exchange rate foreign equity option and the American equity-linked foreign exchange option are studied in detail.     

ANALYTICAL COMPARISONS OF OPTION PRICES IN STOCHASTIC VOLATILITY MODELS

This paper gives an ordering on option prices under various well-known martingale measures in an incomplete stochastic volatility model. Our central result is a comparison theorem that proves convex option prices are decreasing in the market price of volatility risk, the parameter governing the choice of pricing measure. The theorem is applied to order option prices under q -optimal pricing measures. In doing so, we correct orderings demonstrated numerically in Heath, Platen, and Schweizer ( Mathematical Finance , 11(4), 2001) in the special case of the Heston model.     

实物期权及其在风险投资中的应用

从广义的期权定义中引出实物期权的概念,对金融期权和实物期权进行比较分析;并借鉴金融期权的定价方法,得出实物期权的定价公式。通过计算风险投资项目中实物期权的价值,比较含有实物期权的风险投资项目与一般投资项目的价值,可以看出在风险投资中引入实物期权的思想,对风险投资家做出正确的投资决策,以及对风险资本的保值增值有重大的指导意义。

OPTION PRICING AND HEDGING WITH EXECUTION COSTS AND MARKET IMPACT

This paper considers the pricing and hedging of a call option when liquidity matters, that is, either for a large nominal or for an illiquid underlying asset. In practice, as opposed to the classical assumptions of a price‐taking agent in a frictionless market, traders cannot be perfectly hedged because of execution costs and market impact. They indeed face a trade‐off between hedging errors and costs that can be solved by using stochastic optimal control. Our modeling framework, which is inspired by the recent literature on optimal execution, makes it possible to account for both execution costs and the lasting market impact of trades. Prices are obtained through the indifference pricing approach. Numerical examples are provided, along with comparisons to standard methods.     

Optimal Stopping and the American Put

We show that the problem of pricing the American put is equivalent to solving an optimal stopping problem. the optimal stopping problem gives rise to a parabolic free-boundary problem. We show there is a unique solution to this problem which has a lower boundary. We identify an integral equation solved by the boundary and show that it is the unique solution to this equation satisfying certain natural additional conditions. the proofs also give a natural decomposition of the price of the American option as the sum of the price of the European option and an "American premium."     

Long memory in continuous-time stochastic volatility models

This paper studies a classical extension of the Black and Scholes model for option pricing, often known as the Hull and White model. Our specification is that the volatility process is assumed not only to be stochastic, but also to have long-memory features and properties. We study here the implications of this continuous-time long-memory model, both for the volatility process itself as well as for the global asset price process. We also compare our model with some discrete time approximations. Then the issue of option pricing is addressed by looking at theoretical formulas and properties of the implicit volatilities as well as statistical inference tractability. Lastly, we provide a few simulation experiments to illustrate our results.
