In this paper we examine the empirical performance of affine jump diffusion models with stochastic volatility in a time … method. The support for a stochastic volatility model including jumps in both prices and volatility is strong and the model …

metal price series is investigated, as well as time-varying volatility. The results demonstrate that allowing for jumps and … time-varying volatility provides statistically important improvements in the modelling or prices, relative to GBM. These …

This paper tests the expectations hypothesis of the term structure of implied volatility for several national stock … market indexes. The tests indicate that the slope of at-the-money implied volatility over different maturities has predictive … ability for future short-dated implied volatility, although not to the extent predicted by the expectations hypothesis. The …

Bermudan cancelable features. We consider a three-factor pricing model with FX volatility skew which results in a time …

Recent empirical studies report predictable dynamics in the volatility surfaces implied by observed index option prices …

We apply the directed acyclic graph and spillover index models and find significant evidence of both implied volatility … contagion and spillover. First, the global implied volatility smiles exhibit strong regional clustering. The European and … them, the European index options markets demonstrate the strongest implied volatility smile contagion. Second, there exists …

This paper examines the cross-dynamics of volatility term structures implied by foreign exchange options. The data used … common factors can explain a vast proportion of the variation in volatility term structures across currencies. Furthermore …, the results indicate that the euro is the dominant currency, as the implied volatility term structure of the euro is found …
