Identifying the New Keynesian Phillips Curve
نویسندگان
چکیده
Phillips curves are central to discussions of inflation dynamics and monetary policy. New Keynesian Phillips curves describe how past inflation, expected future inflation, and a measure of real marginal cost or an output gap drive the current inflation rate. This paper studies the (potential) weak identification of these curves under generalized methods of moments (GMM) and traces this syndrome to a lack of persistence in either exogenous variables or shocks. The authors employ analytic methods to understand the identification problem in several statistical environments: under strict exogeneity, in a vector autoregression, and in the canonical three-equation, New Keynesian model. Given U.S., U.K., and Canadian data, they revisit the empirical evidence and construct tests and confidence intervals based on exact and pivotal Anderson-Rubin statistics that are robust to weak identification. These tests find little evidence of forward-looking inflation dynamics. JEL classification: E31, C32

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...

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 ...

Abstract In this paper, the effect of foreign sector macro-variable on inflation dynamics and firms’ pricing behavior has been investigated in the context of a small open economy New Keynesian Phillips Curve. This curve is derived and estimated for a developing oil-exporting economy suffering from Dutch Disease. This version of NKPC is an extension of Leith and Malley’s (2007) small open econom...
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...
متن کاملThe Nonlinearity of the New Keynesian Phillips Curve: The Case of Tunisia
This article seeks to check the nonlinearity of the Phillips curve in Tunisia for the 1993–2012 period, relying on a hybrid new Keynesian Phillips curve modeled via a Logistic Smooth Transition Regression (LSTR) model with endogenous variables. We estimate this model using the nonlinear instrumental variables. The empirical results corroborate the new Keynesian assumption ofprice rigidity and s...
متن کاملThe Phillips Curve: Forward-Looking Behavior and the Inflation Premium
We use the inflation premium—the difference between nominal and real interest rates—as a proxy for expected inflation in the context of the New Keynesian Phillips Curve. Using data from inflation-indexed and nominal bonds we estimate a forward-looking Phillips curve for the United Kingdom over the period 1985-2004. The proposed model describes UK inflation dynamics considerably better than does...
