5 Stochastic volatility
E Ghysels, AC Harvey, E Renault - Handbook of statistics, 1996 - Elsevier
Publisher Summary The class of stochastic volatility (SV) models has its roots in both,
mathematical finance and financial econometrics. In fact, several variations of SV models …

There is a risk-return trade-off after all
This paper studies the intertemporal relation between the conditional mean and the
conditional variance of the aggregate stock market return. We introduce a new estimator that …

Macroeconomics and the reality of mixed frequency data
E Ghysels - Journal of Econometrics, 2016 - Elsevier
Many time series are sampled at different frequencies. When we study co-movements between
such series we usually analyze the joint process sampled at a common low frequency. …

Alternative models for stock price dynamics
This paper evaluates the role of various volatility specifications, such as multiple stochastic
volatility (SV) factors and jump components, in appropriate modeling of equity return …

Stock market volatility and macroeconomic fundamentals
We revisit the relation between stock market volatility and macroeconomic activity using a
new class of component models that distinguish short-run from long-run movements. We …

Predicting volatility: getting the most out of return data sampled at different frequencies
We consider various mixed data sampling (MIDAS) regressions to predict volatility. The
regressions differ in the specification of regressors (squared returns, absolute returns, realized …

Ex ante skewness and expected stock returns
We use option prices to estimate ex ante higher moments of the underlying individual securities’
risk‐neutral returns distribution. We find that individual securities’ risk‐neutral volatility, …
