  • 详情 创业企业定价的复合实物期权模型
    Abstract: In this paper, we assume the R&D research for new products and new business models of an entrepreneur will get some cash-flow in the future. And because of the patent protection, the entrepreneur will become a monopolist in that defined market. The successful R&D research represents the growth value for the entrepreneur. We assume that the value of growth is the value of the entrepreneur. The total market value of entrepreneur can be understood as a real growth option plus a discounted real exchange option. The first time in the theory, this paper gets the formula of the real compound option under three stochastic parameters. 关键词:创业企业,增长价值,定价,复合实物期权 Keywords: entrepreneur, growth value, pricing, compound real option
  • 详情 从客户关系管理角度论金融混业经营――一个新视角
    从国外实践来看,混业经营是大势所趋,但解释混业现象的国外传统理论未能得到实证结果的有力支撑,本文借鉴国外资源基础理论(Resource based theory),结合对欧美一些综合性银行的调查,从客户关系管理(Customer Relationship Management――CRM)角度分析诠释金融混业经营现象,指出混业经营的目的是维持客户关系、有效提升客户价值,其实质是银行实施的以客户为中心的经营管理战略。本文旨在为中国的金融混业探索提供新的研究视角。
  • 详情 浅析综合性银行发展的内部整合
    随着经济改革体制的不断深入,中国金融业将朝着混业经营的方向发展。综合性银行是一部分金融企业的发展方向。综合性银行是一种可以提供全方位金融服务,并可以持有金融和非金融企业股份的金融机构(Benston, 1994). Saunders and Walter (1994) 和Canals (1997) 描述了不同种类的综合性银行的组织管理形式,Holland (2001)建立了一种理想化的综合性银行管理模型。本文通过对欧美15家银行的调查,并结合中国金融业的具体情况,探讨综合性银行发展中的内部整合问题。 作者认为综合性银行不是简单的增加几个职能部门,也不是简单的并购几家公司,围绕客户关系进行内部结构重组和整合,才是发展综合性银行的关键。本文用资源为基础的理论(Resource based theory)( (Wernerfelt, 1984; Barney, 1991) 和客户价值理论(Woodruff, 1997;Slater, 1997)来分析解释综合性银行的组织结构问题,认为金融企业的客户关系是重要的竞争优势,围绕客户观系组织企业的资源,可以有效提升客户价值。本文分析了国外综合性银行中存在的问题,为中国综合性银行发展的理论和实践提供借鉴。
  • 详情 基于个体消费的银行货币需求分布研究
    文章分析了一个营业日向银行取款的客户数量,该变量服从Poisson分布。将客户按富裕程度分为三个层次,即工薪阶层、较富阶层和富裕阶层,构造出单个客户取款数量的密度函数。并分析了客户对银行货币需求的概率分布,将其归结为一个泛函极值问题,并进行了求解,结论是客户对银行货币需求的分布为指数分布。
  • 详情 美式看跌期权的闭合公式计算方法
    本文提出了基础资产为无红利分配股票的美式看跌期权的第一个闭合计算公式。美式看跌期权赋予其持有人在期权存续期的任一时刻、以约定价格出售股票的权利但非义务。在过去的几十年中,特别是在Black-Scholes模型给出欧式期权的定价公式后,人们在美式期权的定价方面做了大量探索,提出了不少方法,但尚无闭合公式求法。本文提出了一个美式看跌期权提前行权的最优策略,即当且仅当一个美式看跌期权被提前行权时的收益大于其对应的欧式看跌期权的价值时,该美式看跌期权才会被提前行权。基于这一策略,本文提出了一系列紧密关联的定理并最终推出了一个闭合计算公式。另外,基于该闭合公式得出的结论,本文还指出了Merton(1973)有关永久美式看跌期权(perpetual American put option)的模型是不妥的,明确指出永久美式看跌期权(股票无红利)的价格等于该期权的执行价格。This paper proposes a closed form solution for pricing an American put option on a non-dividend paying stock. An American put option grants its holder rights, but not obligation to sell a stock in a fixed price at any time up until maturity. In the past decades, there is no closed form solution for pricing American options although many people made great efforts. In this paper, an optimally early exercise strategy of an American put option on a non-dividend paying stock is set up. That is, an American put option should be early-exercised when the maximum option premium of early exercise is no less than the value of its European counterpart; otherwise, it should not be early-exercised. Based on this strategy, a series of lemmas is proposed and a closed form formula is drawn. Also, this paper shows that Merton (1973)’s formula does not do a good job for pricing perpetual American put options and shows the price of a perpetual American put option on a non-dividend paying stock is equal to the strike price.

  • 详情 Current Problems and Reforms of Chinese Financial System
    China’s non-performing loans were as high as 35 percent of state banks’ total loans, or about RMB 3,549 billion (about 40 percent of its GDP) in 2000. The adequacy ratios of the four state banks were only between 1.4 percent to 4.6 percent in September 2000. Moreover, non-bank financial institutions as a group as early as 1996 had non-performing assets equal to 50 percent of their total assets. By Western accounting standards, China’s most financial institutions are insolvent. Be conventional standards for measuring financial sector robustness, China is past the point at which a systemic banking crisis might be expected. China faces enormous risks delaying the state bank reforms due to increasing capital account leaks, increasing large proportion of household deposits in banks’ total liabilities, and gradual structural shift of Chinese saving behavior. China needs to resolutely address the financial reforms soon to avoid a financial crisis, which will lead to a broad anti-regime coalition against the Chinese government. Nevertheless, China faces enormous difficulties. First, the 2000 Chinese official estimate puts the financial cost of restructuring the state banks at RMB 2,260 billion ($273 billion), or close to 30 percent of GDP. Second, the current AMC scheme is fraught with difficulties. Finally, the required financial sector reforms are closely interlinked with many other reforms such that a sequential or partial approach will not be effective.
  • 详情 gamma时变过程与Black Scholes期权定价模型的改进
    本文介绍了一种Black Scholes期权定价模型的改进方法,这种方法是通过将gamma过程作为时变过程嵌入Black Scholes期权定价模型中的布朗运动来实现的。在给出了相应的欧式看涨期权价格的解析解的基础上,本文对改进模型的定价性能进行了实证检验。

  • 详情 中国股市IPOs低价发行的一种解释――风险转移补偿假说
    IPOs(Initial Public Offerings)称首次公开发行的普通股,在我国称为新股,主要争论集中在对IPOs的短期和长期表现以及IPOs低价发行原因等方面。本文将在国内外学者已有研究的基础上,进一步深入研究IPOs低价发行的成因,认为影响IPOs低价发行最关键的因素乃是不确定性即风险因素,IPOs低价发行是对老股东把风险转移给新股东的补偿。
