Sequential Arbitrage Measurements and Interest Rate Envelopes

This paper proposes new measures that provide us with the level of sequential arbitrage in bond markets. All the measures vanish in an arbitrage-free market and all of them are positive otherwise. Each measure is generated by a dual pair of optimization problems. Primal problems permit us to compute optimal sequential arbitrage strategies, if available. Each dual problem generates a concrete proxy for the term structure of interest rates. The set of proxies allows us to obtain the exact market price of any bond and may measure several effects. For instance, the credit risk spread of nondefault free bonds, or the embedded option price of callable or extendible bonds. The developed theory has been tested empirically.     

有交易成本的回望期权定价研究

基于标的资产价格的几何布朗运动假设，Black—Seholes模型运用连续交易保值策略成功解决了完全市场下的欧式期权定价问题。然而，在实际的金融市场中，存在着数量可观的交易成本。本文主要研究了在不完全市场下有交易成本的回望期权的定价问题，并且利用Ito公式，得到了在该模型下期权价格所满足的微分方程。     

障碍期权推广到几何平均资产情况下的定价公式

平均期权是亚式期权,其到期收益依赖于某个形式的整个期权有效期内或是其一部分时段内标的资产的平均价格.障碍期权指的是期权是否有效或是否执行决定于标的资产价格在期权有效期内是否碰上障碍.本文主要讨论几何平均资产在期权有效期内设有障碍的期权定价公式,并运用反射原理和回望期权的方法来推导出期权的定价公式.     

An Eulerian‐Lagrangian method for option pricing in finance

This article is devoted to the development and application of an Eulerian‐Lagrangian method (ELM) for the solution of the Black‐Scholes partial differential equation for the valuation of European option contracts. This method fully utilizes the transient behavior of the governing equations and generates very accurate option's fair values and their derivatives also known as option Greeks, even if coarse spatial grids and large time steps are used. Numerical experiments on two standard option contracts are presented which show that the ELM method (favorably) compares in terms of accuracy and efficiency to many other well‐perceived methods. © 2006 Wiley Periodicals, Inc.

美式利率期权定价的抛物型变分不等式

应用PDE方法对美式利率期权定价问题进行理论分析.在CIR利率模型下美式利率期权定价问题可归结为一个退化的一维抛物型变分不等式.通过引入惩罚函数证明了该变分不等式的解的存在唯一性,然后研究了自由边界的一些性质,如单调性,光滑性和自由边界在终止期的位置.     

LAND DEVELOPMENT AND WILDERNESS CONSERVATION POLICIES UNDER UNCERTAINTY: A SYNTHESIS

The effects of uncertainty and irreversibility on land management are examined in an infinite horizon Arrow-Fisher-Henry conservation model with non-linear land-use welfare function which accounts for the possible role of breakthrough benefits stemming from the genetic resources of wilderness. The effects of uncertainty on optimality and certainty-equivalent development strategies are examined. Crucially, “jump” decision rules are shown to be generally non-optimal for managing wilderness areas.

Vector Majorization and a Robust Option Replacement Trading Strategy

We show that vector majorization and its related preference sets can be used to establish useful option pricing bounds for a robust option replacement investment strategy. This robust trading strategy can help to overcome some of the difficulties in implementing arbitrage option trading strategies when there exists model inaccuracy. Dedicated to Boris Mordukhovich on his 60th birthday.
