Recent labor market reforms in Germany aim, among other things, at reducing unemployment by restricting passive unemployment measures, emphasizing local labor market policies and re-structuring public employment services. This paper uses extensive individual administrative and regional aggregate...

This paper analyses two aspects of environmental regulations triggered by ecoinnovations. First, whether there are long term effects of regulation on innovation. Second, whether the impact of different types of regulation differ by type of the environmental benefit of the innovations. To answer...

In this paper we derive nonparametric bounds for the cumulative incidence curve within a competing risks model with partly identified interval data. As an advantage over earlier attempts our approach also gives valid results in case of dependent competing risks. We apply our framework to...

This paper examines the determinants of gross labour flows in a context where modeling the migration decision as a wage-maximizing process may be inadequate due to regional wage rigidities that result from central wage bargaining. In such a context, the framework that has been developed by...

Many countries, especially in Europe, have ambitious goals to transform their national energy systems towards renewable energies. Technological change in both renewable production and efficient use of energy can help to make these targets come true. Using a panel of German firms linked to the...

This study investigates productivity effects to firms introducing new environmental technologies. The literature on within-firm organisational change and productivity suggests that firms can get higher productivity effects from adopting new technologies if complementary organisational changes...

This paper aims to shed light on the role of technological opportunities for green innovation by studying the case of Green ICT innovation. We test two hypotheses: (1) Firms active in low-opportunity technological areas are less innovative; (2) Firms active in low-opportunity technological areas...

The literature on within-firm organizational change and productivity suggests that firms can make more efficient use of certain technologies if complementary forms of organization are adopted. This issue may be of even greater importance for the case of greenhouse gas (GHG) abatement...

In many situations the applied researcher wants to combine different data sources without knowing the exact link and merging rule. This paper introduces a theoretical framework how two different regional administrative data sources can be merged. It presents different merging schemes based on...

We compare two options of integrating discrete working time choice of heterogenous households into a general equilibrium model. The first, known from the literature, produces household heterogeneity through a working time preference parameter. We contrast this with a model that directly...
