A New Keynesian Phillips curve for Tunisia : Estimation and analysis of sensitivity

In this paper, we study some empirical issues in the estimation of a New-Keynesian Phillips curve for Tunisia. In this purpose, we compare the performance of the strict and hybrid forms in the validation of data. In addition, we try to establish the sensitivity of the Phillips curve estimation to some empirical speci�cations. It includes the measures to be used for the output gap variable, as well as the implementation of the generalized method of moments for the estimation of this curve.
