Purpose – The aim of this paper is to examine the accuracy of GARCH and provide a comparison of GARCH-type and the other time series models in financial commodity markets. Design/methodology/approach – First, a model fitting is performed to choose suitable models with conditional volatility...

This paper presents a mathematical model for contingent claim pricing in a preannounced policy. There are some properties in the model. First, one can distinguish the preannouncement effects on the mean and volatility of asset returns. Second, the European call option pricing solution in the...

With the intersection of market and credit risk, the first contribution is to derive the analytic formulas of the Credit Linked Notes (CLNs) and the leveraged total return CLNs issued by an Special Purpose Vehicle (SPV) or the protection buyer. The second contribution is to prove that the values...

The article makes two contributions to the literature. The first contribution is to derive a closed-form solution of Taiwanese capped options. We also provide the properties of Taiwanese capped options and the phenomenon of delta jump at monitoring dates. When the interest rate changes...

This article provides a closed-form valuation formula for the Black-Scholes options subject to interest rate risk and credit risk. Not only does our model allow for the possible default of the option issuer prior to the option's maturity, but also considers the correlations among the option...

This paper uses a multivariate normal inverse Gaussian model to develop closed-form pricing formulas for both geometric and arithmetic basket options. For geometric basket options, an exact analytical solution is possible; for arithmetic basket options, the formula is an approximation. The model...

In this study, we empirically investigate the properties of gold returns, and the European gold options are priced when the underlying gold price dynamics are driven by Markov-modulated jump-diffusion processes. Specifically, the jump events are captured by a compound Poisson process with a...

This paper aims to establish a portfolio strategy using information of lead–lag relationship. The efficient frontier in mean–variance theory has confirmed that the spectrum strategy established by the lead–lag relationship yields superior performance assuming the same volatility. And then...

In this article, we construct a general model, which considers the borrower's financial and non-financial termination behavior, to derive the closed-form formula of the mortgage value for analyzing the yield, duration and convexity of the risky mortgage. Since the risks of prepayment and default...
