A Simple Test of the New Keynesian Phillips Curve
نویسنده
چکیده
We propose a way to test the New Keynesian Phillips Curve (NKPC) without estimating the structural parameters governing the curve, i.e. price stickiness and firms’ backwardness. Using this strategy we can test the NKPC avoiding the identification problems related to the GMM approach. We find that it does not exist a combination of the structural parameters which is consistent with US data. This result does not necessarily imply that the idea of a forward looking price setting behaviour should be entirely disregarded, as the rejection might be due to the failure of the joint hypothesis of rational expectations. Thus further research should be aimed at providing alternative models for agents’ expectations. JEL Classification: C32, E31

متن کاملIntroduction to the New Keynesian Phillips Curve
I n most industrialized economies inflation tends to be pro-cyclical; that is, inflation is high during times of high economic activity. When economic activity is measured by the unemployment rate this statistical relationship is known as the Phillips curve. The Phillips curve is sometimes viewed as a menu for monetary policymakers, that is, they can choose between high inflation and low unempl...

This paper presents a simple New-Keynesian small open economy model allowing for labour to be supplied both domestically and abroad with a locational preference to work at home rather than abroad. From this small change in the otherwise standard setup follows an important implication for the Phillips-curve: The opening of the "labour account" reduces the output-ination trade-o¤, i.e. the Phill...
