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...

This paper develops a model of unemployment fluctuations. The model keeps the architecture of the Barro and Grossman (1971) general disequilibrium model but replaces the disequilibrium framework on the labor and product markets by a matching framework. On the product and labor markets, both...

In this paper, I investigate the scope of a model with exogenous habit formation - or 'catching up with the Joneses', see Abel (1990) - to generate the observed equity premium as well as other key macroeconomic facts. Along the way, I derive restrictions for four out of eight parameters for a...

We build an analytically and computationally tractable stochastic equilibrium model of unemployment in heterogeneous labor markets. Facing search frictions within markets and reallocation frictions between markets, workers endogenously separate from employment and endogenously reallocate between...

Average hourly real wage series from the Labor Productivity and Costs (LPC) program and the Current Employment Statistics (CES) program have evolved very differently over the past decades. While the LPC wage has grown consistently over time and become markedly more volatile since the mid-1980s,...

By international comparison the productivity development of the overall economy in Germany has taken a serious hit after the reunification boom. Since then Germany has fallen behind not only in comparison to the USA and emerging-market nations like South Korea, but also in comparison to other EU...

Die gesamtwirtschaftliche Produktivitätsentwicklung in Deutschland ist nach dem Wiedervereinigungsboom im internationalen Vergleich deutlich eingebrochen. Nicht nur gegenüber den USA und Schwellenländern wie Südkorea, sondern auch im Vergleich zu anderen EU-Staaten fiel Deutschland seitdem...

This paper examines the stability of balanced paths of expansion or contraction in closed macroeconomic models as typical cases of homogeneous dynamical systems. Examples of known two-dimensional deterministic and stochastic models are discussed. The appendix presents the mathematical tools and...
