This paper analyzes the cost of disinflation under real wage rigidities in a micro-founded New Keynesian model. Unlike Blanchard and Galí (2007) who carried out a similar analysis in a linearized framework, we take non-linearities into account. We show that the results change dramatically, both...

In the standard New Keynesian sticky price model the central bank faces no contradiction between the stabilization of inflation and the stabilization of the welfare relevant output gap after a productivity shock hits the economy. When the standard model is enhanced by real wage rigidities or...

We analyze optimal monetary policy when a central bank has to learn about an unknown coefficient that determines the effect of surprise inflation on aggregate demand. We derive the optimal policy under active learning and compare it to two limiting cases---certainty equivalence policy and...

We analyze determinacy and stability under learning (E-stability) of rational expectations equilibria in the Blanchard and Galí (2006, 2008) New-Keynesian model of inflation and unemployment, where labor market frictions due to costs of hiring workers play an important role. We derive results...

Bei Vorliegen nach unten starrer Nominallöhne erschwert niedrige Inflation Reallohnanpassungen und führt so möglicherweise zu erhöhter gleichgewichtiger Arbeitslosigkeit. Dieser Aufsatz analysiert die wachsende Evidenz zu nach unten starren Nominallöhnen. Es werden nicht nur die...

What is the influence of stock market valuations on monetary policy? We use a forward-looking Taylor rule model to examine if monetary policy since the 19 October 1987 stock market crash has been influenced by the valuation of the stock market. We estimate the model using revised and real-time...

This article shows how the existence of production inflexibilities in the form of capacity utilization constraints conditions the magnitude of the response of macroeconomic variables to a money supply stimulus. Capacity is modeled under explicit microfoundations, where the existence of...

Inflation has been low when productivity growth has been high. This occurs because the Federal Reserve has not adjusted nominal income growth in response to changes in productivity growth, implying that an acceleration in trend productivity growth leads to a deceleration in inflation. The...

Previous proposals suggesting monetary policy makers target private-sector forecasts have been shown to be problematic. As policy becomes more effective, private-sector forecasts become less informative. Under perfect stabilization private-sector forecasts provide no useful guidance to monetary...
