Using firm-level data from the German manufacturing sector, we estimate a dynamic, structural model of the firm’s decision to invest in R&D and quantify the cost and longrun benefit of this investment. The model incorporates and quantifies linkages between the firm’s R&D investment, product...

In this paper, human capital investments are evaluated by assuming heterogeneous returns to education. We use the potential outcome approach to measure the causal effect of human capital investments on earnings as a continuous treatment effect. Empirical evidence is based on a sample of West...

We contribute to the literature on the long-run effect of fiscal consolidation on economic growth by applying a novel method for quantitative case studies. Relying on a qualitative (narrative) definition of fiscal consolidations based on an examination of historical policy documents and using...

We investigate the sensitivity of consumer surplus estimates to parametric assumptions on individual preference heterogeneity in a discrete choice framework. We compare results from a parametric random coefficients logit model and a recently proposed nonparametric sieve estimator. In particular,...

Using data from the 1997 and 2002 waves of the German Socio-Economic Panel and from official statistics, the present paper studies whether natives are less supportive of state help for the unemployed in regions where the share of foreigners among the unemployed is high. The effect of immigration...

Knowledge and technological change are often assumed to be the driving forces for long run economic growth. Regions with a higher level of knowledge compared to other regions exhibit a higher per-capita income on average. Agglomeration effects can lead to a steady increase of income and widen...

Economic theory suggests that financing constraints may occur due to capital market imperfections. These particularly affect investments in innovation projects as such projects are typically characterized by a high degree of uncertainty, complexity and specificity. Financing innovation...

This paper analyses the impact of business process outsourcing (BPO) on firm productivity based on a comprehensive German firm-level panel data set covering manufacturing and service industries. The growing importance of service inputs into the production process is undisputed. Firms...

In this paper, we analyze oil price impacts on unemployment for Germany. Firstly, we survey theoretical and empirical literature on the oil-unemployment relationship and relate them to the German case. Secondly, we illustrate this issue within the framework of a vector autoregression (VAR)...

The paper aims at testing Florida's concept of the Creative Class using panel data for 323 West German regions for the time period 1975-2004. Applying a dynamic system approach based on GMM, we find that the local concentration of the Creative Class has predictive power for the economic...
