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 and...

This paper investigates empirically rm investment behavior in research and development (R&D). Firms make investments in R&D in order to produce innovations. These innovations in turn improve the rm s future productivity level, pro tability and incentives to invest in R&D. Using German rm-level...

This article investigates how a firm's financial strength affcts its dynamic decision to invest in R&D. We estimate a dynamic model of R&D choice using data for German firms in high-tech manufacturing industries. The model incorporates a measure of the firm's financial strength, derived from its...

In this article we study differences in the returns to R&D investment between firms that sell in international markets and firms that only sell in the domestic market. We use German firm-level data from the high-tech manufacturing sector to estimate a dynamic structural model of a firm's...

Economic theory predicts that outsourcing public services to private firms will reduce costs, but the effect on quality is ambiguous. We explore quality differences between publicly and privately owned ambulances in a setting where patients are as good as randomly assigned to ambulances of...

In this paper, we estimate a dynamic structural model of a rm s decision to invest in R&D and use it to measure the expected long-run bene t from R&D investment. We apply the model to German rms in ve high-tech manufacturing industries and distinguish rms by whether they sell in just the...

In this paper we develop a structural empirical model that allows us to estimate the impact of R&D on firm profitability through two channels. In the first channel, R&D investment by the firm can impact the firm's production efficiency and lower its marginal cost. This productivity channel...

[Introduction] Over the last few years there has been an increasing debate on supply security in the German healthcare system. In particular, concerns have been raised with respect to the shortage of pharmacies in rural regions. While the low level of demand for pharmaceutical services and...

We investigate the interdependence of debt financing and R&D activities of young firms. Using micro-level data of the KfW/ZEW Start-up Panel, our estimation results show that firm characteristics are more important than personal characteristics of the founders for explaining young firms'...
