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...

This note shows that the Svensson versus McCallum and Nelson controversy battled in the Federal Reserve Bank of St. Louis Review (September/ October 2005) can be mapped into a static version of a New Keynesian macro model that consists of an IS-equation, a Phillips curve and an inflation...

Over the last decade a new consensus model has emerged in monetary macroeconomics, labelled New Keynesian macroeconomics (Clarida et al., 1999). It consists of three simple building blocs: a forward-looking IS-equation that is derived from the optimization problem of a representative household,...

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...

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...

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...

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...

It is often said that after the crisis economic textbooks have to be rewritten. However, as surveys show, almost all professors continue using the standard IS-LM/AS-AD model as the workhorse for undergraduate training. This paper shows that the IS-LM/AS-AD model is not only full of obvious...
