Bayesian Estimation of the GARCH(1,1) Model with Student-t Innovations

Ardia, David; Hoogerheide, Lennart F. - Tinbergen Instituut - 2010

This note presents the R package bayesGARCH (Ardia, 2007) which provides functions for the Bayesian estimation of the parsimonious and effective GARCH(1,1) model with Student-<I>t</I> innovations. The estimation procedure is fully automatic and thus avoids the tedious task of tuning a MCMC sampling...</i>

The Impact of Effect Size Heterogeneity on Meta-Analysis: A Monte Carlo Experiment

Koetse, Mark J.; Florax, Raymond J.G.M.; Groot, Henri … - Tinbergen Instituut - 2007

In this paper we use Monte Carlo simulation to investigate the impact of effect size heterogeneity on the results of a meta-analysis. Specifically, we address the small sample behaviour of the OLS, the fixed effects regression and the mixed effects meta-estimators under three alternative...

Correcting for Primary Study Misspecifications in Meta-Analysis

Koetse, Mark J.; Florax, Raymond J.G.M.; Groot, Henri … - Tinbergen Instituut - 2005

In non-experimental sciences the errors associated with model misspecifications in primarystudies carry over to meta-analysis. We use Monte Carlo simulations to analyse the effects ofthese misspecifications on results of a meta-analysis using a meta-estimator that calculates asimple average...

Testing I(1) against I(d) alternatives in the presence of deteministic components

Dolado, Juan J.; Gonzalo, Jesús; Mayoral, Laura - Department of Economics and Business, Universitat … - 2005

This paper discusses the role of deterministic components in the DGP and in the auxiliary regression model which underlies the implementation of the Fractional Dickey-Fuller (FDF) test for I(1) against I(d) processes with d € [0, 1). This is an important test in many economic applications...

A Measure-Valued Differentiation Approach to Sensitivity Analysis of Quantiles

Heidergott, Bernd; Volk-Makarewicz, Warren - Tinbergen Instituut - 2013

Quantiles play an important role in modelling quality of service in the service industry and in modelling risk in the financial industry. Recently, Hong showed in his breakthrough papers that efficient simulation based estimators can be obtained for quantile sensitivities by means of sample path...

Forecasting the Variability of Stock Index Returns with Stochastic Volatility Models and Implied Volatility

Hol, Eugenie; Koopman, Siem Jan - Tinbergen Instituut - 2000

In this paper we compare the predictive abilility of Stochastic Volatility (SV)models to that of volatility forecasts implied by option prices. We develop anSV model with implied volatility as an exogeneous var able in the varianceequation which facilitates the use of statistical tests for...

On the short-time behavior of the implied volatility for jump-diffusion models with stochastic volatility

Alòs, Elisa; León, Jorge A.; Vives, Josep - Department of Economics and Business, Universitat … - 2006

In this paper we use Malliavin calculus techniques to obtain an expression for the short-time behavior of the at-the-money implied volatility skew for a generalization of the Bates model, where the volatility does not need to be neither a difussion, nor a Markov process as the examples in...
