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.

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. 相似文献

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.

This paper examines the variance ratio tests in studies of transitory volatility and concludes that the variance ratio is an appropriate test of trading structure differences only under certain assumptions regarding the evolution of underlying stock prices and the autocorrelation structure of returns. This result raises caution as to the interpretation of results bases upon the 24-hour variance ratio methodologies in studies of transitory volatility and trading structure effects. A numerical example indicates that errors in inferences can be severe. 相似文献

This paper uses a probabilistic change-of-numeraire technique to compute closed-form prices of European options to exchange
one asset against another when the relative price of the underlying assets follows a diffusion process with natural boundaries
and a quadratic diffusion coefficient. The paper shows in particular how to interpret the option price formula in terms of
exercise probabilities which are calculated under the martingale measures associated with two specific numeraire portfolios.
An application to the pricing of bond options and certain interest rate derivatives illustrates the main results. 相似文献

This research presents a method for estimating the parameters of the binomial option pricing model necessary to appropriately price calls on assets with asymmetric end-of-period return distributions. Parameters of the binomial model are shown to be a function of the mean, variance, and skewness of the underlying return distribution. It is also shown that failure to incorporate skewness results in the mispricing of the call. 相似文献

In this paper we study the pricing and hedging of options whose payoff is a polynomial function of the underlying price at
expiration; so-called ‘power options’. Working in the well-known Black and Scholes (1973) framework we derive closed-form
formulas for the prices of general power calls and puts. Parabola options are studied as a special case. Power options can
be hedged by statically combining ordinary options in such a way that their payoffs form a piecewise linear function which
approximates the power option's payoff. Traditional delta hedging may subsequently be used to reduce any residual risk. 相似文献

Instead of concentrating on the selection of the optimal transfer pricing method, this paper focuses on the consequences of international transfer pricing for multinational entities. A sample of U.S.-based multinational firms is employed to determine if transfer pricing results in measurable financial outcomes. Results of the study indicate that firms employ international transfer pricing to meet a variety of objectives. The dollar value of international transfers and the foreign sales percentage are both significant explanatory variables for the financial outcomes of these objectives. 相似文献
