We extend the basic (representative-household) New Keynesian [NK] model ofthe monetary transmission mechanism to allow for a spread between the interestrate available to savers and borrowers, that can vary for either exogenous orendogenous reasons. We nd that the mere existence of a positive...

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...

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...

This paper discusses the paper "The Source of Historical Economic Fluctuations: An Analysis using Long-Run Restrictions" by Neville Francis and Valerie A. Ramey. It argues that these authors have made great progress both in the precise measurement of labor input as well as determining the effect...

Stylized facts on output and interest rates in the U.S. have so far proved hard to match with business cycle models. But these findings do not acknowledge that the economy might well be driven by different shocks, and by each in different ways. I estimate covariances of output, nominal and real...

New Keynesian models of monetary policy predict no role for monetary aggregates, in the sense that the level of output, prices, and interest rates can be determined without knowledge of the quantity of money. This paper evaluates the empirical validity of this prediction by studying the effects...

In this paper, we examine formally Keynes' idea that higher order beliefs can drivea wedge between an asset price and its fundamental value based on expected future payoffs. In a dynamic noisy rational expectations model, higher order expectations add an additional term, which we call the higher...

We study identification in a class of linear rational expectations models. For any givenexactly identified model, we provide an algorithm that generates a class of equivalentmodels that have the same reduced form. We use our algorithm to show that a modelproposed by Jess Benhabib and Roger...

In a simple New Keynesian model, we derive a closed form solution for the inflationpersistence parameter as a function of the policy weights in the central bank’s Taylorrule. By estimating the time-varying weights that the FED attaches to inflationand the output gap, we show that the...

Die Hauptthese dieses Beitrags betrifft das bleibende Verdienst von Milton Friedman alsÖkonom und Gesellschaftstheoretiker. Sie besagt, dass die Ökonomik als wissenschaftlicheDisziplin durch Keynes und den Keynesianismus in eine Grundlagenkrise gestürzt wurde, ausder sie maßgeblich durch die...
