Relative forecasting performance of volatility models : Monte Carlo evidence
Lux, Thomas; Morales-Arias, Leonardo - 2010
A Monte Carlo (MC) experiment is conducted to study the forecasting performance of a variety of volatility models under alternative data generating processes (DGPs). The models included in the MC study are the (Fractionally Integrated) Generalized Autoregressive Conditional Heteroskedasticity...

Parameter estimation and forecasting for multiplicative lognormal cascades
Leövey, Andrés E.; Lux, Thomas - 2011
We study the well-known multiplicative Lognormal cascade process in which the multiplication of Gaussian and Lognormally distributed random variables yields time series with intermittent bursts of activity. Due to the non-stationarity of this process and the combinatorial nature of such a...

Financial power laws : empirical evidence, models, and mechanism
Lux, Thomas (contributor) - 2006
Financial markets (share markets, foreign exchange markets and others) are all characterized by a number of universal power laws. The most prominent example is the ubiquitous finding of a robust, approximately cubic power law characterizing the distribution of large returns. A similarly robust...

Modeling and forecasting crude oil price volatility : evidence from historical and recent data
Lux, Thomas; Segnon, Mawuli; Gupta, Rangan - 2015
This paper uses the Markov-switching multifractal (MSM) model and generalized autoregressive conditional heteroscedasticity (GARCH)-type models to forecast oil price volatility over the time periods from January 02, 1875 to December 31, 1895 and from January 03, 1977 to March 24, 2014. Based on...
