Numerous tests designed to detect realized jumps over a fixed time span have been proposed and extensively studied in … the financial econometrics literature. These tests differ from 'long time span tests' that detect jumps by examining the … implications of these findings, and 'time-span robust' tests indicate that the prevalence of jumps is not as universal as might be …

We discuss several multivariate extensions of the Multiplicative Error Model to take into account dynamic interdependence and contemporaneously correlated innovations (vector MEM or vMEM). We suggest copula functions to link Gamma marginals of the innovations, in a specification where past...

This paper develops a method to improve the estimation of jump variation using high frequency data with the existence of market microstructure noises. Accurate estimation of jump variation is in high demand, as it is an important component of volatility in finance for portfolio allocation,...

Estimation of GARCH models can be simplified by augmenting quasi-maximum likelihood (QML) estimation with variance targeting, which reduces the degree of parameterization and facilitates estimation. We compare the two approaches and investigate, via simulations, how non-normality features of the...

We provide empirical evidence of volatility forecasting in relation to asymmetries present in the dynamics of both … return and volatility processes. Using recently-developed methodologies to detect jumps from high frequency price data, we … estimate the size of positive and negative jumps and propose a methodology to estimate the size of jumps in the quadratic …
