Several approaches for subset recovery and improved forecasting accuracy have been proposed and studied. One way is to apply a regularization strategy and solve the model selection task as a continuous optimization problem. One of the most popular approaches in this research field is given by...

Changing the income tax progressivity in labour markets with collective wage bargaining generates a trade-off. On the one hand, higher progressivity distorts individual labour supply decisions at the hours-of-work margin, on the other hand, it reduces unemployment by exerting downward pressure...

This paper deals with the impact of the $/€ exchange rate on German exports in the period from 1995Q1 to 2008Q4. Our main aim is to identify 'pain thresholds' for German exporters. We rely on a non-linear model according to which suddenly strong spurts of exports occur when changes of the EXR...

This paper provides evidence that interbank markets are tiered rather than flat, in the sense that most banks do not lend to each other directly but through money center banks acting as intermediaries. We capture the concept of tiering by developing a core-periphery model, and devise a procedure...

The increased wind energy supplied to many electricity markets around the world has to be balanced by reliable back up units or other complementary measures when wind conditions are low. At the same time wind energy impacts both, the utilization of thermal power plants and the market prices....

We review the labor market implications of recent real-business-cycle models that successfully replicate the empirical equity premium. We document the fact that all models considered in this survey with the exception of Boldrin, Christiano, and Fisher (2001) imply a negative correlation of...

Im Vorfeld der Bundestagswahl 2013 findet in Deutschland eine intensive Debatte über die Umverteilungswirkung der Einkommensteuer statt. Insbesondere mit der Senkung des Spitzensteuersatzes auf zwischenzeitlich 42 und nun 45 Prozent wird eine überproportionale Bevorzugung hoher Einkommen...
