Abstract
Most empirical studies show that three factors are sufficient to explain all the relevant uncertainties inherent in option prices. In this paper, we consider a three-factor CIR model exhibiting unspanned stochastic volatility (USV), which means that it is impossible to fully hedge volatility risk with portfolios of bonds or swaps. The incompleteness of bond markets is necessary for the existence of USV. Restrictions on the model parameters are needed for incompleteness. We provide necessary and sufficient conditions for a three-factor CIR model that generates incomplete bond markets. Bond prices are exponential affine functions of only the two term-structure factors, independent of the unspanned factor. With our three-factor CIR model exhibiting USV, we derive the dynamic form of bond futures prices. By introducing the exponential solution of a transform and using the Fourier inversion theorem, we obtain a closed-form solution for the European zero-coupon option prices. The pricing method is efficient for taking into account the existence of unspanned stochastic volatility.
期刊介绍：
The proliferation of derivative assets during the past two decades is unprecedented. With this growth in derivatives comes the need for financial institutions, institutional investors, and corporations to use sophisticated quantitative techniques to take full advantage of the spectrum of these new financial instruments. Academic research has significantly contributed to our understanding of derivative assets and markets. The growth of derivative asset markets has been accompanied by a commensurate growth in the volume of scientific research. The Review of Derivatives Research provides an international forum for researchers involved in the general areas of derivative assets. The Review publishes high-quality articles dealing with the pricing and hedging of derivative assets on any underlying asset (commodity, interest rate, currency, equity, real estate, traded or non-traded, etc.). Specific topics include but are not limited to: econometric analyses of derivative markets (efficiency, anomalies, performance, etc.) analysis of swap markets market microstructure and volatility issues regulatory and taxation issues credit risk new areas of applications such as corporate finance (capital budgeting, debt innovations), international trade (tariffs and quotas), banking and insurance (embedded options, asset-liability management) risk-sharing issues and the design of optimal derivative securities risk management, management and control valuation and analysis of the options embedded in capital projects valuation and hedging of exotic options new areas for further development (i.e. natural resources, environmental economics. The Review has a double-blind refereeing process. In contrast to the delays in the decision making and publication processes of many current journals, the Review will provide authors with an initial decision within nine weeks of receipt of the manuscript and a goal of publication within six months after acceptance. Finally, a section of the journal is available for rapid publication on `hot'' issues in the market, small technical pieces, and timely essays related to pending legislation and policy.
