This paper examines the existence of Berge equilibrium. Colman et al. provide a theorem on the existence of this type of equilibrium in the paper [Colman, A. M., Körner, T. W., Musy, O. and Tazdaït, T. [2011] Mutual support in games: Some properties of Berge equilibria, J. Math. Psychol. 55,...

Nous décrivons les dynamiques de l'inflation issues des différentes hypothèses d'ajustement des prix rencontrées dans la littérature néo-keynésienne. Pour chaque modèle nous calculons la réponse de l'inflation et du produit suite à un choc sur le taux de croissance de la masse...

La Persistance de l'Inflation dans les Modèles Néo-Keynésiens, by Mohamed Safouane Ben Aïssa and Olivier Musy We derive the inflation dynamics implied by the different hypothesis on price adjustment existing in the New Keynesian litterature. We study the response of output and inflation in...

We analyse the behaviour of an economy characterized by staggered pricing, with price contracts either specified in nominal terms (Taylor, 1980), or in real terms (Fuhrer and Moore, 1995). We focus on the response of these models to a permanent and unexpected disinflation policy. It is advanced...

This paper analyses the impact of the disinflation policy timing on the sign and the magnitude of the sacrifice ratio in a modified price and wage staggered model of Blanchard (1986). When wages are updated every four quarters and prices every two quarters, we show that a “cold-turkey”...

This paper presents a classification of the different new Phillips curves existing in the literature as a set of choices based on three assumptions: the choice of the structure of price adjustments (Calvo or Taylor), the presence of backward indexation, and the type of price contracts (fixed...

We consider a static game with conjectural variations where some firms make conjectures while others do not. Two propositions are proved. We first show that there exists a continuum of conjectural variations such that the conjectural equilibrium locally coincides with the Stackelberg equilibrium...
