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...

This paper uses a static and dynamic gravity model of trade to investigate the link between German development aid and exports from Germany to the recipient countries. The findings indicate that in the long run,German aid is associated with an increase in exports of goods that is larger than the...

In this paper we study the sources of wage growth. We identify the contribution to such growth of general, sector specific and firm specific human capital. Our results are interpretable within the context of a model where the returns to human capital may be heterogeneous and where firms may...

The German Environmental Liability Law (ELL) of 1991 has introduced far-reaching civil liability for environmental damages with the aim to increase firms? efforts to prevent accidents. Previous studies find poor evidence that this goal has actually been achieved. One and a half decades after the...

Labor force participation rates of mothers in Austria and Germany are similar, however full-time employment rates are much higher among Austrian mothers. In order to find out to what extent these differences can be attributed to differences in the tax transfer-system, we perform a comparative...

Motivated by economic-theory concepts - the Fisher hypothesis and the theory of the term structure - we consider a small set of simple bivariate closed-loop time-series models for the prediction of price inflation and of long- and short-term interest rates. The set includes vector...

This empirical research note documents the relationship between composition of a firm's workforce (with a special focus on age and gender) and its performance with respect to innovative activities (outlays and employment in research and development (R&D)) for a large representative sample of...

This paper contributes to the literature by providing the first evidence on the link between innovation activities (measured by the share of engineers and scientists in the workforce) and exports of German business services firms based on a large representative longitudinal sample of...

This study provides the first comparative evidence of foreign and domestic acquisitions in Germany. A propensity score matching approach combined with a difference-in-difference estimator were performed separately for foreign and domestic acquisitions to account for a general takeover effect....

This paper uses newly available data for German business services firms to test a hypothesis derived by Bustos (AER 2011) in a model that explains the decision of heterogeneous firms to export and to engage in R&D. Using a non-parametric test for first order stochastic dominance it is shown...
