In this paper, we explore the benefits from a supply-side oriented fiscal tax policy within the framework of a New Keynesian DSGE model. We show that countercyclical tax rules, which are contingent on the observed welfare gap or on the cost-push shock and levied on value added, remarkably reduce...

In this paper we carry over a static version of a New Keynesian Macro Model developed in previous papers (see Bofinger, Mayer, and Wollmershäuser 2002) to a monetary union. For a similar approach see (Uhlig 2002). We will show in particular that a harmonious functioning of a monetary union...

This paper explores whether the cost channel solves the price puzzle. We set-up a New Keynesian DSGE model and estimate it for the euro area by adopting a minimum distance approach. Our findings suggest that - under certain parameter restrictions which are not rejected by the data - the cost...

This paper presents a New Keynesian model that dwells on the role of banks in the cost channel of monetary policy. Banks extend loans to firms in an environment of monopolistic competition by setting the loan rate according to a Calvo-type staggered price setting approach, which means that the...

This paper addresses the credit channel in Germany by using aggregate data. We present a stylized model of the banking firm, in which banks decide on their loan supply in the light of uncertainty about the future course of monetary policy. Applying a vector error correction model (VECM), we...

Dieses vorläufige Papier beinhaltet keinerlei neuen Erkenntnisse, sondern fasst lediglich einige zentrale Aspekte der makroökonomischen Lerntheorie (siehe Evans, Honkajohja (2001)) knapp zusammen. Es wird der Frage nachgegangen ob rationale Erwartungsgleichgewichte lernbar sind. Lernen...

Within this paper we specify a symmetric two country model for the euro area to evaluate monetary and fiscal policy interaction with decentralized fiscal authorities. Obviously this calls for rules which neatly balance the chances and perils. Thereby we show that stringent rules are a...

For the open economy the workhorse model in intermediate textbooks still is the Mundell-Fleming model, which basically extends the IS-LM model to open economy problems. The purpose of this paper is to present a simple New Keynesian model of the open economy, that introduces open economy...

While the IS/LM-AS/AD model is still the central tool of macroeconomic teaching it has been criticised by several economists. The model is unable to deal with a monetary policy that uses the interest rate as its operating target ( Romer [2000]). Walsh [2002] has criticised that it is not suited...

The last years have witnessed a sharp increase of interest in monetary policy rules (see Taylor [1999]). This normative branch of monetary policy tries to evaluate the performance of alternative monetary policy rules in terms of associated monetary policy outcomes. Nevertheless this exercise is...
