We estimate the effect of R&D spillovers on sales realized by products new to the firm (imitation) and new to the market (innovation). It turns out that spillovers from rivals lead to more imitation, while inputs from customers and research institutions enhance original innovation

This paper tests for the sensitivity of R&D to financing constraints conditional on restrictions in external financing. Financing constraints of firms are identified by an exogenously calculated rating index. Restrictions in external financing are determined by (i) the specific time period...

We develop a simple model of competition for the market that shows that, contrary to the Arrow view, endogenous entry threat in a market induces the average firm to invest less in R&D and the incumbent leader to invest more. We test these predictions with a Tobit model based on a unique dataset...

Many studies investigate the relationship between R&D expenditures as an input and patents as an intermediate product or output of a knowledge production function. We suggest that the productivity of research in patent production functions has been underestimated in the literature, as scholars...

This paper presents the results of an empirical test concerning the auction model of Gilbert and Newbery (1982). The study uses data on German companies in order to analyze expenditures for technology licenses. Aside of standard control variables the motives for innovation expenditures are also...

We study whether the incumbent or the (potential) entrant invests more into R&D, using data of about 3500 German firms from 1992 to 1995 that explicitly asks firms for their motives in undertaking innovative activity, making it possible to take account intended, not just completed, market entry....

Principle-agent theory suggests managers might under-invest into R&D for reasons of risk tied to project failure, such as reduced remuneration and job loss. However, managers might over-invest into innovation for reasons of growth implying higher remuneration, power and prestige. Using a sample...

This paper considers the effect of different firm leadership on the innovative performance of firms from seven EU countries. We investigate whether owner-led or manager-led firms achieve a larger share of their turnover with product innovations. Economic theory does not propose clear answers to...
