Liquidity and asset prices: how strong are the linkages?
Dreger, Christian; Wolters, Jürgen - 2009
The appropriate design of monetary policy in integrated financial markets is one of the most challenging areas for central banks. One hot topic is whether the rise in liquidity in recent years has contributed to the formation of price bubbles in asset markets. If strong linkages exist, the...

Causal inference by independent component analysis with applications to micro- and macroeconomic data
Moneta, Alessio; Entner, Doris; Hoyer, Patrik; Coad, Alex - 2010
Structural vector-autoregressive models are potentially very useful tools for guiding both macro- and microeconomic policy. In this paper, we present a recently developed method for exploiting non-Gaussianity in the data for estimating such models, with the aim of capturing the causal structure...

Testing the new Keynesian Phillips curve
Bårdsen, Gunnar; Jansen, Eilev S.; Nymoen, Ragnar - 2002
The dynamic properties of the The New Keynesian Phillips curve (NPC) is analysed within the framework of a small system of linear di.erence equations.We evaluate the empirical results of existing studies which uses ‘Euroland’ and US data. The debate has been centered around the...

Tail-dependence in stock-return pairs
Fortin, Ines; Kuzmics, Christoph - 2002
The empirical joint distribution of return-pairs on stock indices displays high tail-dependence in the lower tail and low tail-dependence in the upper tail. The presence of tail-dependence is not compatible with the assumption of (conditional) joint normality. The presence of asymmetric-tail...

Specification Testing in Hawkes Models
Gresnigt, Francine; Kole, Erik; Franses, Philip Hans - 2015
We propose various specification tests for Hawkes models based on the Lagrange Multiplier (LM) principle. Hawkes models can be used to model the occurrence of extreme events in financial markets. Our specific testing focus is on extending a univariate model to a multivariate model, that is, we...

Out-of-sample Comparison of Copula Specifications in Multivariate Density Forecasts
Diks, Cees; Panchenko, Valentyn; van Dijk, Dick - 2008
We introduce a statistical test for comparing the predictive accuracy of competing copula specifications in multivariate density forecasts, based on the Kullback-Leibler Information Criterion (KLIC). The test is valid under general conditions: in particular it allows for parameter estimation...

Comparing the Accuracy of Copula-Based Multivariate Density Forecasts in Selected Regions of Support
Diks, Cees; Panchenko, Valentyn; Sokolinskiy, Oleg; van … - 2013
This paper develops a testing framework for comparing the predictive accuracy of copula-based multivariate density forecasts, focusing on a specific part of the joint distribution. The test is framed in the context of the Kullback-Leibler Information Criterion, but using (out-of-sample)...

Messung des Marktrisikos mit generalisierter autoregressiver bedingter heteroskedastischer Modellierung der Volatilität: Ein Vergleich univariater und multivariater Konzepte
Krasnosselski, Nikolai; Cremers, Heinz; Sanddorf, Walter - 2014
The globalisation on financial markets and the development of financial derivatives has increased not only chances but also potential risk within the banking industry. Especially market risk has gained major significance since market price variation of interest rates, stocks or exchange rates...

Estimating the rank of the spectral density matrix
Camba-Méndez, Gonzalo; Kapetanios, George - 2004
The rank of the spectral density matrix conveys relevant information in a variety of statistical modelling scenarios. This note shows how to estimate the rank of the spectral density matrix at any given frequency. The method presented is valid for any hermitian positive de?nite matrix estimate...
