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...

In this article we demonstrate how challenging greenhouse gas reduction targets of up to 95% until 2050 can be achieved in the German electricity sector.1 In the analysis, we focus on the main requirements to reach such challenging targets. To account for interdependencies between the...

Es wird das Konzept für ein makroökonomisches Strukturmodell mit integriertem Innovationsprozesskern zur Analyse und Projektion der Wirtschaftsentwicklung in Deutschland vorgestellt. Das geplante Modell soll explizit die Auswirkungen des immer bedeutsamer werdenden IuK-technologischen...

The paper develops a sequential migration model and derives a worker's optimal policies for migration and employment. With the worker's simulated reservation wage functions for employment and migration, a stationary equilibrium is defined. In that equilibrium, stationary distributions of...

A nonparametric Data Envelopment Analysis (DEA) is performed on hospitals in the federal state of Saxony (Germany) and in Switzerland. This study is of interest from three points of view. First, contrary to most existing work, patient days are not treated as an output but as an input. Second,...

We use a dynamic framework and panel methodology to investigate the determinants of a firms' time-varying capital structure. Our sample comprises 706 European firms from France, Germany, Italy and the U.K. over the period from 1983 to 2002. If capital structure adjustment is costly, firms may...

This paper studies the role of inflation in the determination of financial asset prices. We estimate an Intertemporal Capital Asset Pricing Model à la Merton (1973), with inflation as an independent source of risk, for France and Germany. Our study also allows us to evaluate how the different...

This paper estimates a structural dynamic life-cycle model of outmigration where, in each period, immigrants choose whether to work in the host country, not to work but remain in the host country, or outmigrate. The model incorporates several features of existing life-cycle theories of...

This paper quantifies the degree of market power in the German wholesale electricity market. A fundamental model is used to derive competitive marginal cost estimators which are compared with observed electricity prices. Marginal costs are calculated focusing on market fundamentals such as plant...

Europe's increasing import dependency in natural gas facilitates a number of new infrastructure projects. However, up to now it has always been diffcult to assess the full impact of these projects as interdependencies within the whole European gas infrastructure system were hard to predict. We...
