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...

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...

This paper investigates empirically firm 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 firm's future productivity level, pro tability and incentives to invest in R&D. Using German...

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...
