We study optimal monetary policy in an analytically tractable New Key-nesian DSGE-model with an emission externality. Empirically, emissions are strongly pro-cyclical and output in the flexible price equilibrium overreacts to productivity shocks, relative to the efficient allocation. At the same...

I derive the imperfect-common-knowledge Phillips curve under the assumption of Rotemberg pricing. The curve differs from the Calvo version in one important aspect. Expectations of future relative prices impact in ation.

Those of professional forecasters do. For a wide range of time series models for the euro area and its member states we find a higher average forecast accuracy of models that incorporate information on inflation expectations from the ECB’s SPF and Consensus Economics compared to their...

We show that if business cycles are driven by financial shocks, the interplay between the effective lower bound (ELB) and the costs of external financing can generate an additional supply-side channel, which causes a disconnect between inflation and output. In normal times, factor costs dominate...

This paper examines the reasons for the declining path of inflation since the 1970s. In particular, it focusses on the role of globalization - covering both changes in the global market structure and technical and structural developments in trade and production. In addition, the paper deals with...

The standard New Keynesian model suffers from the so-called .macro-micro pricing conflict: in order to match the dynamics of inflation implied by macroeconomic data, the model needs to assume an average duration of price contracts which is much longer than what is observed in micro data. Here I...
