This paper studies the impact of process and product innovations introduced by firms on employment growth in these firms. A simple model that relates employment growth to process innovations and to the growth of sales separately due to innovative and unchanged products is developed and estimated...

This study presents a novel empirical approach to identify financing constraints for innovation based on the idea of an ideal test as suggested by Hall (2008). Firms were offered a hypothetical payment and were asked to choose between alternatives of use. If they choose additional innovation...

The previous literature on the determinants of individual well-being has failed to fully account for the interdependencies in well-being at the family level. This paper develops an ordered probit model with multiple random effects that allows to identify the intrafamily correlation in...

The paper evaluates the German health care reform of 1997, using the individual number of doctor visits as outcome measure. A new econometric model, the Probit-Poisson-log-normal model with correlated errors, describes the data better than existing count data models. Moreover, it has an...

The paper studies the demand for foreign graduates at the firm level. Using a unique dataset on recruitment policies of firms in four European countries, the determinants of demand for internationally mobile high-skilled employees are established. I investigate the number, origin, skills, and...

This study presents a novel empirical approach to identify financing constraints for innovation based on the concept of an ideal test (Hall 2008). Firms were offered a hypothetical payment and were asked to choose between alternatives of use. If they selected additional innovation projects, they...

The paper studies the demand for foreign university graduates at the firm level. Using a unique dataset on recruitment policies of firms in four European countries, the determinants of demand for internationally mobile highly skilled employees are established. I investigate the number, origin,...

The paper evaluates the German health care reform of 1997, using the individual number of doctor visits as outcome measure and data from the German Socio- Economic Panel for the years 1995-1999. A number of modified count data models allow to estimate the effect of the reform in different parts...
