Testing the New Keynesian Phillips curve through Vector Autoregressive models: Results from the Euro area
نویسندگان
چکیده
This paper addresses the issue of testing the ‘hybrid’ New Keynesian Phillips Curve (NKPC) through Vector Autoregressive (VAR) systems and likelihood methods, giving special emphasis to the case where the variables are non-stationary. The idea is to use a VAR for both the inflation rate and the explanatory variable(s) to approximate the dynamics of the system and derive testable restrictions. Attention is focused on the ‘inexact’ formulation of the NKPC. Empirical results over the period 1971-1998 show that the NKPC is far from providing a ‘good first approximation’ of inflation dynamics in the Euro area.

The harmful effects of chronic high inflation in the economy led the governments and country’s monetary authorities seek to reduce or eliminate this phenomenon. Therefore it’s very important to predict how inflation moves providing an appropriate economic model is a crucial factor to forecast inflation, so on. In this regard, in the present research, we attempt to generate a appropriate model f...
متن کاملEvaluating the New Keynesian Phillips Curve under VAR-based Learning
This paper proposes an econometric evaluation of the New Keynesian Phillips Curve (NKPC) in the euro area, under a particular specification of the adaptive learning hypothesis. The key assumption is that agents’ perceived law of motion is a Vector Autoregressive (VAR) model, whose coefficients are updated by maximum likelihood estimation as the information set increases over time. Each time new...

In this paper an open economy model of the New Keynesian Phillips Curve incorporating three different factors of production, domestic labor and imported as well as domestically produced intermediate goods, is developed and estimated for 9 euro area countries and the euro area aggregate. This general model nests existing closed economy and open economy models as special cases. We find that struc...
متن کاملTesting the New Keynesian Model on U.S. and Euro Area Data
I apply the Johansen and Swensen (1999, 2004) method of testing exact rational expectations within the cointegrated VAR (Vector Auto-Regressive) model, to testing the New Keynesian (NK) model. This method permits the testing of rational expectation systems, while allowing for non-stationary data. The NK-model is tested on quarterly U.S. and Euro area time series data. I find that the restrictio...

T here is always uncertainty about the soundness of an economic model’s structure and parameters. Therefore, central banks normally face with uncertainty about the key economic explanatory relationships. So, policymaker should take into account the uncertainty in formulating monetary policies. The present study is aimed to examine robust optimal monetary policy under uncertainty, by ...
