We extend a recent methodology, Bayesian stochastic model specification search (SMSS), for the selection of the unobserved components (level, slope, seasonal cycles, trading days effects) that are stochastically evolving over time. SMSS hinges on two basic ingredients: the non-centered...

This paper considers the performance of different long-memory dynamic models when forecasting volatility in the stock … market using implied volatility as an exogenous variable in the information set. Observed volatility is separated into its … performance. Implied volatility conveys incremental information about future volatility in both specifications, improving …

This paper provides theory as well as empirical results for pre-averaging estimators of the daily quadratic variation of asset prices. We derive jump robust inference for pre-averaging estimators, corresponding feasible central limit theorems and an explicit test on serial dependence in...

Recent work by Engle and Lee (1999) shows that allowing for long-run and short-run components greatly enhances a GARCH model’s ability fit daily equity return dynamics. Using the risk-neutralization in Duan (1995), we assess the option valuation performance of the Engle-Lee model and compare...

Our analysis is motivated by the recent literature on realized (volatility) measures, such as the realized variance, that … are imperfect estimates of actual volatility. In an empirical analysis using realized measures for the DJIA stocks we find …
