This paper presents a comparison of alternative option pricing models based either on jump-diffusion nor stochastic volatility data generating processes. We assume either a smooth volatility function of some previously defined explanatory variables or a model in which discrete-based observations...

This paper proposes a GARCH-type model allowing for time-varying volatility, skewness and kurtosis. The model is estimated assuming a Gram-Charlier series expansion of the normal density function for the error term, which is easier to estimate than the non-central t distribution proposed by...

We document a surprising pattern in market prices of S&P 500 index options. When implied volatilities are graphed against a standard measure of moneyness, the implied volatility smirk does not flatten out as maturity increases up to the observable horizon of two years. This behavior contrasts...

In this study, we use both parametric and non-parametric methods to test the property of martingale restriction in KOSPI 200 index options market. Our results provide strong evidence that the property is violated. Further regression analysis and robustness checks suggest that market friction...

This paper empirically examines the relationship between trading volume and conditional volatility of returns in the Tunisian stock market within the framework of the mixture of distribution hypothesis (MDH) and the sequential information arrival hypothesis (SIAH). Through this study, we...

This paper employs multivariate GARCH models with a BEKK specification to show significant shock and volatility spillovers from mature bond markets into select emerging Asian local currency bond markets. Results reveal that while the growth of individual bond markets in recent years has been...

Despite the high volatilities recorded for electricity prices, there seems to be little demand for options on electricity. One reason for the disinterest in electricity options could arise from uncertainty about how to price these options. This study uses recent econometric advances to...
