The asymmetric and persistent adjustment of the European real exchange rates is investigated using the framework of non-linear cointegration. The episodes of slow mean-reversion dynamics over the period from 1979 to 1999 are explained. A test of unit root against STAR cointegration is proposed...

Cet article analyse le comportement cyclique du cours du Dow Jones et notamment ses propriétés de mémoire longue à travers une nouvelle classe de modèles ARFIMA semiparamétriques avec erreurs GARCH hyperboliques, notée SEMIFARMA-HYGARCH ; cette classe inclut une tendance déterministe non...

This paper presents a 2-regime SETAR model with different long-memory processes in both regimes. We briefly present the memory properties of this model and propose an estimation method. Such a process is applied to the absolute and squared returns of five stock indices. A comparison with simple...

We revisit the evidence of the existence of a long-run link between financial intermediation and economic growth, by testing of cointegration between the growth rate of real GDP, control variables and three series reflecting financial intermediation. We consider a model with a factor structure...

This article studies the world stock markets integration for developed and emerging countries and investigate its effects on diversification. We test a partially segmented ICAPM using an asymmetric multivariate GARCH-in-Mean specification. Our results support the integration hypothesis and...
