Has heightened uncertainty been a major contributor to the Great Recession and the slow recovery in the U.S.? To answer this question, we identify exogenous changes in six uncertainty proxies and quantify their contributions to GDP growth and the unemployment rate. Our results are threefold....

In this paper we analyse to what extent movements in oil prices can help to explain business cycle fluctuations in Germany.We proceed in several steps:As a starting point we use a standard real business cycle model for the German economy and introduce energy as an additional factor in the...

We present an Uncertainty Perception Indicator (UPI) for Germany based on the dynamic topic modelling technique RollingLDA. In contrast to conventional LDA, where all data is processed in one go, the recursive structure of RollingLDA ensures that data is made available for modeling as soon as it...

In this paper, we estimate a small New Keynesian dynamic stochastic general equilibrium (DSGE) model for Germany for the period from 1975 to 1998 and use it to identify the structural shocks, which have driven the business cycle. For this purpose we apply indirect inference methods, that is we...
