El presente artículo analiza la correlación entre Estados Unidos y Asia teniendo en cuenta el impacto de la crisis financiera actual. Dentro de los países asiáticos se escoge un mercado desarrollado, Japón, y distintos mercados emergentes, entre los cuales se encuentran los tigres...

The persistent nature of equity volatility is investigated by means of a multi-factor stochastic volatility model with time varying parameters. The parameters are estimated by means of a sequential matching procedure which adopts as an auxiliary model a time-varying generalization of the HAR...

Using dynamic conditional correlations and networks, we bring a novel framework to define the integration and segmentation of emerging countries. The individual EMBI+ spreads of 13 emerging countries from 01/2003 to 12/2013 are used to compare their interaction structure before (phase 1) and...

This article evaluates a large collection of systemic risk measures based on their ability to predict macroeconomic downturns. We evaluate 19 measures of systemic risk in the US and Europe spanning several decades. We propose dimension reduction estimators for constructing systemic risk indexes...

The paper is dedicated to the methodology of calculation, description of the properties and practical appliance of the realized volatility estimation, and its usage in the VaR calculation. The aim of the research is comparing of the realized volatility calculation methods, some of them are...

We studied systemic risk in European sovereign debt markets before and after the onset of the Greek debt crisis, taking the conditional value-at-risk (CoVaR) as a systemic risk measure, characterized and computed using copulas. We found that, before the debt crisis, sovereign debt markets were...

In this paper, we introduce a new class of bivariate threshold VAR cointegration models. In the models, outside a compact region, the processes are cointegrated, while in the compact region, we allow different kinds of possibilities. We show that the bivariate processes from a 1/2-null recurrent...

We introduce a methodology for measuring default risk connectedness that is based on an out-of-sample variance decomposition of model forecast errors. The out-of-sample nature of the procedure leads to \realized" measures which, in practice, respond more quickly to crisis occurrences than those...

Scholars worldwide have provided both theoretical and empirical insights into financial market contagion. The devastation from the recent financial crisis is immeasurable, and researchers commonly believe that the crisis seemingly originated from the U.S. and spread immediately to the other...

Forecasting portfolio risk requires both, estimation of marginal return distributions for individual assets and the dependence structure of returns as well. In this paper, we concentrate on Value at Risk as a popular risk measure and combine elliptical copulas with time varying Dynamic...
