Optimal oil production under mean-reverting Lévy models with regime switching
This paper models the evolution of the oil price as a mean-reverting regime-switching jump–diffusion process.
Modeling impacts of stock jumps on real estate investment trust returns with application to value-at-risk
This paper aims to model the impact of extreme stock jumps on REIT returns.
Pricing and hedging options with rollover parameters
This paper consists of a “horse race” study comparing (i) a number of option pricing models, and (ii) roll-over estimation procedures.
Forecasting scenarios from the perspective of a reverse stress test using second-order cone programming
This paper proposes a model for forecasting scenarios from the perspective of a reverse stress test using interest rate, equity and foreign exchange data.
Does higher-frequency data always help to predict longer-horizon volatility?
This paper shows that realized conditional autocorrelation in return residuals is a strong predictor of the relative performance of different frequency models of volatility.
