Asymmetric Response of Volatility: Evidence from Stochastic Volatility Models and Realized Volatility [PDF]

open access: yes, 2004
This paper examines the asymmetric response of equity volatility to return shocks. We generalize the news impact function (NIF), originally introduced by Engle and Ng (1993) to study asymmetric volatility under the ARCH-type models, to be applicable to both stochastic volatility (SV) and ARCH-type models.
