Relation de Phillips, boucle prix-salaire : une estimation par la méthode de Johansen
Abstract
[fre] Relation de Phillips, boucle prix-salaire : une estimation par la méthode de Johansen par Eric Heyer, Hervé Le Bihan et Frédéric Lerais . Nous estimons, sur données trimestrielles françaises, une boucle prix-salaire en utilisant la méthode de Johansen, qui permet de prendre en compte la non-stationnarité des séries et le caractère simultané des interactions. Les prix et salaires étant caractérisés comme des variables I(2), nous spécifions le système en taux de croissance. La courbe de Phillips traditionnelle est alors interprétée comme une relation de cointegration. La spécification retenue permet de tester différentes hypothèses d'indexation et de modéliser les rigidités nominales de court terme. Suivant la démarche de Johansen et Juselius (1995), nous identifions et estimons des équations de prix et salaires de court terme susceptibles de recevoir une interprétation structurelle. [eng] Revisiting the Classic Augmented Phillips Curve for France: a VECM Approach by Eric Heyer, Hervé Le Bihan et Frédéric Lerais . This paper presents an empirical model of a price- wage loop based on French quarterly data. We apply the Johansen maximum likelihood technique to deal with the series' non-stationarity and capture nominal rigidities. Given that prices and wages can be treated as I(2) variables, we estimate a VECM in terms of price and wage differences. The classic augmented Phillips curve is hence interpreted as a cointegration relation. Our specification is used to test different wage and price indexation assumptions and to model short-run nominal rigidities. Two other long-run relations are identified: the mark-up of value-added prices over labour costs and a consumer price inflation equation involving import prices. We also use the Johansen and Juselius (1995) approach to identify and estimate a set of structural short-run price and wage equations.Download Info
