This paper presents the business cycle model that Trygve Haavelmo developed as part of his research program in macroeconomic and monetary theory. Driven by a mismatch between the marginal return to capital and the rate of return required by capital owners, this model generates endogenous cycles....

In their work, Galí, Gertler and Lopez-Salido, GGL, assert that the hybrid New Keynesian Phillips curve (NPC) with dominance of forward-looking behavior and real marginal costs is robust to choices of estimation procedure, details of variables definitions and choice of data samples. In an...

Using a panel data set for OECD countries we replicate the typical features of the New Keynesian Phillips curve models (NPCs) that have been estimated on country data. While this corroborates the NPC also on the macro panel data set, a different conclusion is reached when we test whether the NPC...

We derive aggregate supply (AS) relationships for an intermediate-run macro model. The wage-price spiral provides the conceptual framework for a synthesis of different contesting theoretical and empirical perspectives on the AS curve: the Phillips curve model (PCM) and the wage-price equilibrium...

We give an appraisal of the New Keynesian Phillips curve (NPC) as an empirical model of European inflation. We show that existing evidence reported in favour of the NPC on Euro-area and country data is due to a corroborative research strategy. In particular, goodness-of-fit is a weak criterion,...

Three classes of inflation models are discussed: Standard Phillips curves, New Keynesian Phillips curves and Incomplete Competition models. Their relative merits in explaining and forecasting inflation are investigated theoretically and empirically. We establish that Standard Phillips-curve...

Inflation targeting requires inflation forecasts, yet most models in the literature are either theoretical or calibrated. The motivation for this paper is therefore threefold: We seek to test and implement an econometric model forforecasting inflation in Norway–one economy recently opting for...

We present a dynamic model of real wages in the open economy that encapsulates the well-known “competing claims model” or “incomplete competition model” of real wage determination. In general, the model determines the development of inflation, real wages and the real exchange rate for...

We investigate the importance of employing a valid model for monetary policy analysis. Specifically, we investigate the economic significance of differences in specification and empirical validity of models. We consider three alternative econometric models of wage and price inflation in Norway....
