We show that TFP reacts counter-cyclically to macroeconomic shocks, which we identify by imposing sign restrictions. Counterfactual simulations, based on a New Keynesian DSGE model, show that firms manage to employ labor more efficiently during downturns, which leads to a muted drop in the...

Using a sign restrictions approach, we document that total factor productivity (TFP) moves counter-cyclically in the aftermath of supply and demand side shocks. To interpret our empirical results, we conduct counter-factual simulations, based on a New Keynesian DSGE model in which TFP fluctuates...

We analyze the influence of the fiscal position on the transmission of government spending shocks in a New Keynesian model. We find that once we allow for positive levels of government debt in the steady state, the size of the fiscal multiplier depends strongly on the horizon at which the...

Although the IS/LM-AS/AD model is still the central tool of macroeconomic teaching in most macroeconomic textbooks, it has been criticized by several economists. Colander (1995) demonstrated that the framework is logically inconsistent, Romer (2000) showed that it is unable to deal with a...

Can monetary policy trigger pronounced boom-bust cycles in house prices and create persistent business cycles? We address this question by building heuristics into an otherwise standard DSGE model. As a result, monetary policy sets off waves of optimism and pessimism ('animal spirits') that...

Svensson auf der einen und McCallum und Nelson auf der anderen Seite haben in einer Reihe von Beiträgen kontrovers diskutiert, an welcher geldpolitischer Regel sich eine Notenbank orientieren sollte (vgl. Svensson, L., 2003a, 2003b, 2005, Svensson L., u. Woodford, M. 2005). Hierbei plädiert...
