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...

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...

The empirical performance of macroeconomic exchange rate models is more than disappointing. This dismal result is also reflected in the forecasting capabilities of professional analysts: all in all, analysts are not in a position to beat native random walk forecasts. The root for this deficient...

The study analyses the characteristics of professional exchange rate forecasts for the € /US-$ rate. The results indicate that the quality of forecasts produced by professional economists is rather poor and incompatible with the rational expectations hypothesis. This dismal result is according...

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...
