信用衍生品市场的国际经验与中国发展——基于金融结构和宏观稳定的分析

信用衍生品是国际资本市场上最具创新性的金融工具之一。发展信用衍生品市场不仅可以转移金融机构的信用风险,同时也可以缓解金融脱媒问题,防止资本市场快速膨胀、扭曲银行和金融体系。然而,信用衍生品也有其另一面。美国金融危机显示信用衍生品与金融结构具有复杂的联系机制,可能冲击宏观稳定。本文提出,我国应深入剖析美国的信用衍生品市场与金融结构关系,跟踪国际市场的改革和发展方向,探索符合国情的信用衍生品市场发展道路。     

The price of power: The valuation of power and weather derivatives

Pricing contingent claims on power presents numerous challenges due to (1) the unique behavior of power prices, and (2) time-dependent variations in prices. We propose and implement a model in which the spot price of power is a function of two state variables: demand (load) and fuel price. In this model, any power derivative price must satisfy a PDE with boundary conditions that reflect capacity limits and the non-linear relation between load and the spot price of power. Moreover, since power is non-storable and demand is not a traded asset, the power derivative price embeds a market price of risk. Using inverse problem techniques and power forward prices from the PJM market, we solve for this market price of risk function. During 1999–2001, the upward bias in the forward price was as large as $50/MWh for some days in July. By 2005, the largest estimated upward bias had fallen to $19/MWh. These large biases are plausibly due to the extreme right skewness of power prices; this induces left skewness in the payoff to short forward positions, and a large risk premium is required to induce traders to sell power forwards. This risk premium suggests that the power market is not fully integrated with the broader financial markets.     

结构性金融衍生产品之探讨

结构性金融衍生产品是把固定收益金融产品和金融衍生品进行组合设计出的一种新型金融产品,种类繁多、结构多样。在美洲、欧洲和亚洲都有非常大的市场规模和繁多的产品种类。结构性金融衍生产品增加了资本市场的完备性、深化了市场的风险配置功能、增强了资本的流动性以及提高了金融衍生市场的信用水平。在我国结构性金融衍生产品首先以外币结构性存款的形式出现,自2003年以来得到快速发展。借鉴国际经验,应在鼓励结构性衍生产品发展的同时,着重加速金融衍生品交易所市场的发展。     

Portfolio sensitivity to changes in the maximum and the maximum drawdown

In this article, we define new ‘Greeks’ for financial derivatives: sensitivities to the running maximum and the running maximum drawdown of an underlying asset. Some types of portfolios, such as the net asset value of a hedge fund or performance fees, are sensitive to these parameters. In order to illustrate the concept of the new ‘Greeks’, we derive probabilistic representations of sensitivities for two classes of financial contracts: forwards on the maximum drawdown and lookback options. These results allow us to interpret the delta-hedge of the contracts in a novel way.     

Volatility Spillovers and Contagion During the Asian Crisis: Evidence from Six Southeast Asian Stock Markets

Using a multivariate generalized autoregressive conditional heteroskedasticity (GARCH-M) model, we investigate volatility spillovers in six Southeast Asian stock markets around the time of the 1997 Asian crisis. We focus on interactions with the U.S. market as a world financial market, and with the Japanese market as a regional financial market. We also use bivariate GARCH-M models to examine the behavior of individual markets and their interactions with other markets in the region. All models lend support to the idea of the "Asian contagion," which started in Thailand and rapidly spread to other markets.
