This paper studies the relationship between wages and the degree of firm heterogeneity in a given industry under different wage setting structures. To derive testable hypotheses, we set up a theoretical model that analyses the sensitivity of wages to the variability in productivity conditions in...

Using combined data from the German Pension Insurance and the Federal Employment Agency (BASiD), this study proposes different procedures for imputing the pre-unification education variable in the BASiD data. To do so, we exploit information on education-related periods that are creditable for...

Innovation activities in the German enterprise sector showed two opposing trends over the past two decades: While total innovation expenditures grew substantially, the number of firms conducting innovation activities fell sharply. Innovation expenditures hence concentrate on fewer firms. In this...

In this paper we analyze the conditions under which firms decide to offshore innovation. We consider the role of internal technological capabilities and technological dynamism in the firm environment, distinguishing speed and uncertainty of technological change. Using unique data from the German...

This paper analyses the effects of a social assistance reform in Germany. In contrast to studies which are based on microsimulation methods we use a computable general equilibrium model which incorporates a discrete choice model of labour supply to simulate a variety of reform scenarios. The...

Der Beitrag untersucht, inwieweit hinter der oft konstatierten Investitionsschwäche der europäischen Wirtschaft eine Strukturverschiebung von materiellen zu immateriellen Investitionen steht. Da letztere nur zum Teil unter den Investitionsbegriff der Volkswirtschaftlichen Gesamtrechnung...

This paper investigates the impact of energy policies on the export performance of firms. There has been a long policy debate on potentially negative impacts of cost-increasing energy policies on international competitiveness. We use firm-level data from three countries with similar industry...

The global economic crisis of 2008/2009 hit many firms hard. Faced with rapidly declining sales and highly uncertain economic prospects, firms had to cut costs and reconsider their business strategies. With respect to innovation, cost cutting often means to stop or underresource innovation...

The success of an energy turnaround towards renewables highly depends on the willingness and ability of firms to adopt energy technologies using renewable sources. Existing studies focused on the role of regulation and energy markets (e.g. the price for fossil energy) to explain the diffusion of...

We structurally estimate an equilibrium search model using German administrative data and use this for counterfactual analyses of a uniform minimum wage. The model with worker and firm heterogeneity does not restrict the sign of employment effects a priori and allows for different job offer...
