Macro models generally assume away heterogeneous welfare in assessing policies. We investigate here within two aggregative models ó one with a representative agent, the other a long-used forecasting model of the UK ó whether allowing for di§erences in welfare functions (speciÖcally between...

This paper examines the relationship between cyclical output and inflation in models commonly used for monetary policy analysis. This includes models that incorporate the New Keynesian, Fuhrer-Moore and backward-looking Phillips curves. The main finding is that these models imply a strong...

This paper explicitly models strategic interaction between two independent national fiscal authorities and a single central bank in a simple New Keynesian model of a monetary union. Monetary policy is constrained by the zero lower bound on nominal interest rates. Coordination of fiscal policies...

This paper examines the contemporaneous relationship between the exchange rate re-gime and structural economic reforms for a sample of CEEC/CIS transition countries. We investigate empirically whether structural reforms are complements or substitutes for monetary commitment in the attempt to...

Die Staatsanleihekäufe der EZB sind zu einem Fall für das Bundesverfassungsgericht geworden. Die Autoren des IW Köln argumentieren, dass das Outright-Monetary-Transactions-Programm noch innerhalb der Grenzen des EZB-Mandats liegt, aber wegen seiner Nachteile nur temporär eingesetzt werden...

Nach der EZB-Zinssenkung Anfang November 2013 hat sich Bundesbankpräsident Jens Weidmann mehrfach zu Wort gemeldet, um die Sicht der Bundesbank zum derzeitigen Kurs der Geldpolitik zu erläutern. In seinen Stellungnahmen rechtfertigt er grundsätzlich den derzeit expansiven Kurs der...

This paper develops a model featuring both a macroeconomic and a financial stability objective that speaks to the interaction between monetary and macroprudential policies. First, we find that interest rate rigidities in a monopolistic banking system have an asymmetric impact on financial...

Estimation of conventional Taylor rules for Brazil, Chile, Colombia and Peru shows that central banks increase their repo rate in response to increases in the output gap and, except in Peru, to deviations of inflation expectations from target. Using a Markov-Switching methodology, it is found...

Empirical data suggest that new fi rms tend to grow faster than incumbent firms in terms of their productivity. A sticky-price model with learning-by-doing in new firms fi ts this data and predicts that for plausible calibrations, the optimal long-run inflation rate is positive and between 0.5%...

This paper examines the policy rate recommendations of the Bank of Canada's Governing Council (GC) and the C.D. Howe Institute's Monetary Policy Council (MPC) since 2003. We find, first, that differences in the median recommendations between the MPC and the GC are persistent but small (i.e., 25...
