This paper compares technologies across space and time on the basis of factual and counterfactual substitution elasticities and argues that differences in estimated substitution elasticities should be decomposed into two counterfactual components. While the first component is designed to...

This paper analyzes the persistence of firms' exporting behavior in a panel of West German manufacturing firms. Dynamic binary choice models allow us to distinguish between true and spurious state dependence in firm performance. Using random effects models as well as a recent fixed effect...

This paper deals with the effects of publicly funded research at universities, polytechnics and federal research labs on industrial innovations in Germany. We discuss the characteristics of companies that benefit from the findings of public research institutions. In questioning 2,300 companies...

I study the causal effect of the European Union Emissions Trading System (EU ETS) on the productivity of German manufacturing firms. Using administrative firm-level data, I estimate robust production functions for narrowly defined industries. This approach allows for an endogenous dynamic...

This paper analyses the relevance of information and communication technologies (ICT) for firms' probability of global sourcing of inputs. Using firm-level data from Germany in 2009, which include mainly small and medium-sized firms, the empirical analysis differentiates between manufacturing...

In this paper, I analyse the relationship between offshoring and ICT at the firm level differentiating between manufacturing and services. Using firm-level data from the manufacturing and service sector in Germany and a broad range of ICT measures, overall, the results reveal a positive...

Does investment in social infrastructure affect the productivity of manufacturing firms in developing countries? To test this question, I empirically investigate the impact of social infrastructure indicators at district level on firm productivity using firm level data from Pakistan. I split my...

We investigate the effect of the European Union Emissions Trading System (EU ETS) on the economic performance of manufacturing firms in Germany. Our difference-in-differences framework relies on several parametric conditioning strategies and nearest neighbor matching. As a measure of economic...

Increasing energy efficiency is one of the main goals in current German energy and climate policies. We study the determinants of energy efficiency in the German manufacturing sector based on official firm-level production census data. By means of a stochastic frontier analysis, we estimate the...
