The two oil shocks of the 1970s reduced the GDP growth rate. Since that period, sudden oil price increases have been considered as a major source of economic slowdown. We estimate VAR models and Markov-Switching models to evaluate the impact of oil price increases on French growth. Our results...

Statistical tests in vector autoregressive (VAR) models are typically based on large-sample approximations, involving the use of asymptotic distributions or bootstrap techniques. After documenting that such methods can be very misleading even with fairly large samples, especially when the number...

We propose methods for testing hypothesis of non-causality at various horizons, as defined in Dufour and Renault (1998, Econometrica). We study in detail the case of VAR models and we propose linear methods based on running vector autoregressions at different horizons. While the hypotheses...

French Abstract:Plusieurs matières premières « critiques » jouent un rôle central dans le déploiement detechnologies essentielles à la transition vers une économie bas-carbone. L'approvisionnementfiable et abordable de ces ressources est soumis à des risques du côté de l'offre, face...
