This paper analyses the level of relative specialisation in terms of gross fixed capital formation in EU regions for the period between 1985 and 1994. Controlling for heteroscedasticity and potential endogeneity problems, we get consistent econometric results. Larger market and regional sizes...

Based on a large data set containing information on occupations between 1979 and 1999, this study explores the "black box" surrounding the skill-biased technological change hypothesis by analyzing the mechanisms that induce information technologies to be complementary to employees with higher...

In this paper it is tested which of the various alternative approaches for constructing knowledge spillover pools suggested in existing literature measures the extent to which a firm can costlessly receive external knowlegde best. Since knowledge spillovers are unmeasurable, a 'goodness of fit'...

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,...

Applying a variant of a non-parametric matching estimator, we consider European funding and national funding as heterogeneous treatments, distinguishing and simultaneously analyzing the effect these treatments have on innovation input and performance. In terms of input, getting funding from both...

The effects of childbirth on future labor market outcomes are a key issue for policy discussion. This paper implements a dynamic treatment approach to estimate the effect of having the first child now versus later on future employment for the case of Germany, a country with a long maternity...

We analyze the potential influence of a number of factors on the distribution of equivalized net incomes in Germany over the period 2005/2006 to 2010/11. While income inequality considerably increased in the years before 2005/2006, this trend was stopped after 2005/2006. Among many other...

This paper presents a methodology to identify net demand shocks as well as wage rigidities in heterogeneous labor markets on the basis of nonparametric regression. We show how this approach can be used to make suggestions for immigration policy in economies with labor market rigidities. In an...

We analyze the performance of firms in the German business-related services sector. A quarterly business survey provides the panel data base of our study. Firm performance is measured by the survey respondents' ordinal indication of their changes in total sales. We use a firstorder Markov chain...

This paper makes an empirical contribution to confirm the stylized fact that the performance of firms deteoriates in the years before exit. For this reason we evaluate whether market exits differ significantly in their employment development in the years before market drop-out compared to...
