Much recent research has focused on the development and analysis of extensions of the New Keynesianframework that model labor market frictions and unemployment explicitly. The present paper describessome of the essential ingredients and properties of those models, and their implications for...

Diese Studie untersucht, ob Veränderungen kurzfristiger Zinsen die Kosten liquider Mittel beeinflussen und somit über Preissetzungsentscheidungen der Firmen auf die Inflationsdynamik in Industrieländern wirken. Barth und Ramey (2001) haben zum Beispiel für die USA gezeigt, dass...

For decades economists have considered money illusion aslargely irrelevant. Here we show, however, that money illusion haspowerful effects on equilibrium selection. If we represent payoffs innominal terms almost all subjects play at or close to an inefficientequilibrium whereas if we lift the...

This paper extends a New Keynesian model to include roles for currency and depositsas competing sources of liquidity services demanded by households. It showsthat, both qualitatively and quantitatively, the Barnett critique applies: While a Divisiaaggregate of monetary services tracks the true...

It is common knowledge that the standard New Keynesian model is not able to generate a persistent response in output to temporary monetary shocks. We show that this shortcoming can be remedied in a simple and intuitively appealing way through the introduction of labor turnover costs (such as...

In this paper we propose a novel methodology to analyze optimal policies undermodel uncertainty in micro-founded macroeconomic models. As an application weassess the relevant sources of uncertainty for the optimal conduct of monetary policy within (parameter uncertainty) and across models...

This paper examines whether the existence and the timing of real balance effects contribute to the determination of the absolute price level, as suggested byPatinkin (1949,1965), and if they affect conditions for local equilibrium uniqueness and stability. I show that there exists a unique price...

This paper studies optimal monetary policy with the nominal interest rate as the single policy instrument in an economy, where firms set prices in a staggered way without indexation and real money balances contribute separately to households' utility. The optimal deterministic steady state under...

This paper examines how money demand induced real balance effects contribute to the determination of the price level, as suggested by Patinkin (1949,1965), and if they affect conditions for local equilibrium uniqueness and stability. There exists a unique price level sequence that is consistent...
