Due to growing skepticism over the globalisation process across countries, economists in the emerging market economies (EMEs) are anxious to know how the integration of financial markets was associated with the recent global crisis and whether there could be some key lessons for the broader...

The consistent ranking of multivariate volatility models by means of statistical loss function is a challenging research field, because it concerns the quality of the proxy chosen to replace the unobserved volatility, the set of competing models to be ranked and the kind of loss function. The...

A large number of parameterizations have been proposed to model conditional variance dynamics in a multivariate framework. This paper examines the ranking of multivariate volatility models in terms of their ability to forecast out-of-sample conditional variance matrices. We investigate how...

We assess the predictive accuracy of a large number of multivariate volatility models in terms of pricing options on the Dow Jones Industrial Average. We measure the value of model sophistication in terms of dollar losses by considering a set 248 multivariate models that differ in their...

The ranking of multivariate volatility models is inherently problematic because when the unobservable volatility is substituted by a proxy, the ordering implied by a loss function may be biased with respect to the intended one. We point out that the size of the distortion is strictly tied to the...

In this paper, we propose measures for characterizing the expected and unexpected cost of trading that can be applied to analyze automated electronic auction markets. Using a unique database which contains the full state of the order book for three stocks (Daimler-Chrysler, Deutsche Telekom and...

This article includes a description of the ARCH, GARCH, and EGARCH models and the estimation of their parameters using maximum likelihood. An alternative model is proposed for the analysis of financial series and used to study price and returns series for Gillette stock. The choice of models...

This paper studies a classical extension of the Black and Scholes model of option pricing, often known as the Hull and White model. Our specificity is that the volatility process is assumed not only to be stochastic, but also to have long memory features and properties. We study here the...
