Terms of use: Documents in AbstractThis paper quantifies the impact of the Hartz reforms on matching efficiency, using monthly SOEP gross worker flows . We show that, until the early 2000s, close to 60% of changes in the unemployment rate are due to changes in the inflow rate (job separation). On the contrary, since the implementation of the reforms in the mid-2000s, the importance of the outflow rate (job finding) has been steadily increasing. This indicates that matching efficiency has improved substantially in recent years. Results from an estimated matching function -pointing to efficiency gains of more than 20% -corroborate this finding. JEL Classifications: E24, E32, J63, J64

Abstract This paper develops a 9-dimensional SVAR to investigate the sources of the U.S. business cycle. We extend the standard set of identified shocks to include unexpected changes in commodity prices. Our main result is that commodity price shocks are a very important driving force of macroeconomic fluctuations, second only to investment-specific technology shocks. In particular, we find that commodity price shocks explain a large share of cyclical movements in inflation. Neutral technology shocks and monetary policy shocks seem less relevant at business cycle frequencies. The impulse response dynamics provide support for medium-scale DSGE models, but not for strong price rigidities. Terms of use: Documents inJEL Classification: C32, E32, E52, Q43

This paper evaluates the effectiveness of short-time work [STW] extensions -e.g. relaxing eligibility criteria or implementing new STW schemes -in the OECD during and after the Great Recession. First, we find that the dampening effect of STW on the unemployment rate diminishes at higher take-up rates. Second, only countries with preexisting STW schemes were able to fully exploit the benefits of STW. Third, the effects of STW are strongest when GDP growth is deeply negative at the beginning of recessions. Our results indicate that STW is most effective when used as a fast-responding automatic stabilizer.

This article decomposes fluctuations in the German unemployment rate into changes in inflows (job separation) and outflows (job finding). For this purpose, we construct and examine monthly labour market transition rates from the West German sample of the SOEP (and the CPS) for the period 1984-2009. We explicitly take account of the low level of labour market transition rates in Germany. Our article shows that in West Germany, changes in the inflow rate are more important (about 60%) than changes in the outflow rate, whereas in the USA close to 80% are due to changes in the outflow rate.

The textbook search and matching model suffers from too little amplification and weak internal propagation. We argue that the double failure is due to two negative feedback channels. Intuitively, a decline (rise) in unemployment (vacancies) rises both the wage rate, the "wage channel," and the effective cost to fill a vacancy, the "hiring cost channel." Therefore, we introduce hiring costs and strategic wage bargaining. The interaction between these two modifications limits the impact of both channels effectively and persistently. Thus, the modified model is able to closely match the (inversely) u-shaped impulse responses of vacancies and unemployment.
