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...

[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...

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...

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...

Empirical analysis of firm-level investment in research and development (R&D) and its effect on innovation patterns and productivity has advanced as a result of innovation surveys in many countries. The weak link in the analysis of these surveys is the empirical model of firm R&D choice. In this...

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 long-run benefit of this investment. The model incorporates and quantifies linkages between the firm's R&D investment, product and...

This article investigates how a firm's financial strength affects 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...

This paper estimates a dynamic structural model of discrete R&D investment and quantifies its cost and long-run benefit for German manufacturing firms. The dynamic model incorporates linkages between the firm's R&D choice, product and process innovations, and future productivity and profits. The...

This paper studies the factors underlying the heterogeneity in inventory behavior and performance across retail stores. We use a dynamic model of multi-product retailers and local competition to estimate store productivity and consumers' perceived quality of the shopping experience, and we...
