The "New Keynesian" Phillips Curve (NKPC) states that inflation has a purely forward-looking dynamics. In this paper, we test whether European and US inflation dynamics can be described by this model. For this purpose, we estimate hybrid Phillips curves, which include both backward and...

Estimating a forward-looking monetary policy rule by the Generalized Method of Moments (GMM) has become a popular approach since the influential paper by Clarida, Gali, and Gertler (1998). However , an abundant econometric literature underlines to the unappealing small- samples properties of GMM...

We study how changes in the value of the steady-state real interest rate affect the optimal inflation target, both in the U.S. and the euro area, using an estimated New Keynesian DSGE model that incorporates the zero (or effective) lower bound on the nominal interest rate. We find that this...

We document the presence of both small and large price changes in individual price records from the CPI in France and the US. After correcting for measurement error and cross-section heterogeneity, the size-distribution of price changes has a positive excess kurtosis. We propose an analytical...

[eng] Break Tests : An Application to French Trend GDP by Hervé Le Bihan . This paper presents and applies to GDP recently developed tests for structural change , which allow for the endogenous statistical determination of trend growth break dates and numbers of break-points . These tests serve...

[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...
