We propose a general form of vector Multiplicative Error Model (MEM) for the dynamics of duration, volume and price volatility. The vector MEM relaxes the two restrictions often imposed by previous empirical work in market microstructure research, by allowing interdependence among the variables...

This paper presents theoretical models and their empirical results for the return and variance dynamics of German stocks. A factor structure is used in order to allow for a parsimonious modeling of the first two moments of returns. Dynamic factor models with GARCH dynamics (GARCH(1,1)-M,...

This article investigates the effectiveness of TAIEX (Taiwan Stock Exchange) futures, Taiwan 50 futures, and nonfinance nonelectronics subindex (NFNE) futures for cross hedging the price risk of stock sector indices traded on the Taiwan stock exchange. A state-dependent volatility spillover...

We discuss several multivariate extensions of the Multiplicative Error Model to take into account dynamic interdependence and contemporaneously correlated innovations (vector MEM or vMEM). We suggest copula functions to link Gamma marginals of the innovations, in a specification where past...

We test the importance of multivariate information for modelling and forecasting inflation's conditional mean and variance. In the literature, the existence of inflation's conditional heteroskedasticity has been debated for years, as it seemed to appear only in some datasets and for some lag...

Does a multilateral fiscal rule improve market discipline in a monetary union? This paper studies the impact of political events that systematically undermined the Stability and Growth Pact (SGP) on EMU sovereign default risk for the period 2001 to 2005. For various EMU member countries our...

This paper studies the impact of political events that systematically undermined the Stability and Growth Pact (SGP) on the euro's foreign exchange expectation bias for the period 2001 to 2005. Our findings suggest that euro foreign exchange markets were attentive to the political dispute over...

This paper investigates whether rumours about Greek exit from the euro area have spilled over into other European countries’ sovereign bond yields. Our empirical analysis is based on more than 64,000 daily news items on Grexit between December 2014 and October 2015. We build a Grexit intensity...
