国有资产在产权交易中的定价问题--产权交易招标转让方式下的交易价格分析及改进

本文从博弈论的角度分析了国有企业产权在招标转让交易方式下的交易价格的确定和影响交易价格的因素,分析了招标转让不能使国有企业的所有者得到实际价值的原因,并给出了在招标转让方式下提高国有企业交易价格的方法与途径。     

最优再保险的期权博弈分析

期权博弈理论把期权定价和博弈论结合起来分析在连续时间和不确定性下的动态多人决策问 题。本文运用这种方法首先分析了超额损失再保险的期权特性,用期权定价技术为其定价,然后构建一个 完全信息动态博弈模型分析了原保险人和再保险人的最优策略和均衡结果,给出了无套利条件下的最优超 额损失再保险。与传统精算及其它经济分析文献不同,在此框架下得到的最优再保险保费体现了市场因 素,并反映了利益冲突的保险主体之间顺序动态决策的事实。     

农业水权:农民的紧箍咒还是护身符

在水资源日益短缺、新增水源困难、用水效益较高的形势下,工业用水与城镇用水需从农业水权转让中获得,关于农业水权的研究因此成为水权管理中的重要课题。本文从产权的权利位阶出发,探讨了农业水权的定位,论述了明晰农业水权的必要性与可行性,认为农业水权的界定既是农民的紧箍咒,也是农民的护身符。     

企业剩余分享及其产权机理

企业剩余由资本所有者独享向其他要素所有者共同分享的演进是现代企业治理结构发展的一个重要趋势。本文对剩余和剩余分享进行了界定,分析了剩余分享的几种情形,阐释了剩余分享的内在产权机理及其主要途径。     

论上海产权制度改革与法律支持

伴随现代企业制度改革进程,上海市产权制度改革也取得初步成效。然而,由于产权法律法规跟不上产权制度改革的需要,使之各类产权的界定不准,导致产权交易难和产权市场化程度不高,产权改革的深化遭遇产权法制薄弱的“瓶颈”。产权制度改革最关键的是需要相应的法律支持。因此,一方面,建议全国人大或国务院修改完善有关法律和行政法规;另一方面,加快上海市地方产权法制建设。     

环境产权问题的博弈分析

环境产权是最广泛意义的公有产权,在环境产权的行使中,各行为主体的个体经济目标和环境目标常常存在极大的差异,运用博弈理论阐述环境产权行使中的纳什均衡,旨在说明环境资源保护的社会意义。     

Convergence of numerical methods for valuing path-dependent options using interpolation

One method for valuing path-dependent options is the augmented state space approach described in Hull and White (1993) and Barraquand and Pudet (1996), among others. In certain cases, interpolation is required because the number of possible values of the additional state variable grows exponentially. We provide a detailed analysis of the convergence of these algorithms. We show that it is possible for the algorithm to be non-convergent, or to converge to an incorrect answer, if the interpolation scheme is selected in appropriately. We concentrate on Asian options, due to their popularity and because of some errors in the previous literature.

Pricing U.S. Dollar Index Futures Options: An Empirical Investigation

This paper develops a pricing model and empirically tests the pricing efficiency of options on the U.S. Dollar Index (USDX) futures contract. Empirical tests of the model indicate that the market consistently overprices these options relative to the derived model. This overpricing is more pronounced for out‐of‐the‐money options than for in‐the‐money options and more pronounced for put options than for call options. To validate the above results, delta neutral portfolios are created for one‐ and two‐day holding periods and consistently generate positive arbitrage profits, indicating that on average the market overprices the options on the USDX futures contracts.     

Sub-Replication and Replenishing Premium: Efficient Pricing of Multi-State Lookbacks

The direct valuation procedure of performing discounted expectation to obtain the prices of multi-state lookback options may lead to insurmountable complexity and numerical difficulties. The computation may require numerical differentiation of the joint distribution function of the extremum values, then followed by numerical integration over a semi-infinite domain. In this paper, we illustrate the use of an alternative approach that significantly simplifies the calculations of multi-state lookback option prices. The financial intuition behind the new approach involves the choice of a sub-replicating portfolio and the adoption of the corresponding replenishing strategy to achieve the subsequent full replication of the derivative. The replenishing premium is obtained by performing the integration of an appropriate distribution function over the range of asset price within which under replication occurs. The sub-replication and replenishment procedures may be utilized as hedging strategies for the lookback options. The pricing and hedging properties of multi-state lookback options are also discussed.
