We estimate the determinants of various types of product innovation. Knowledge spillovers from rivals have a positive impact on incremental innovations. This impact is largely independent of the participation in R&D cooperations. Spillovers exert no such independent influence on drastic...

University research provides valuable inputs to industrial innovation. It is therefore not surprising that private sector firms increasingly seek direct access through funding public R&D. This development, however, spurred concerns about possible negative long-run effects on scientific...

Information about the success of a new technology is usually held asymmetrically between the research and development (R&D)-performing firm and potential lenders and investors. This raises the cost of capital for financing R&D externally, resulting in financing constraints on R&D especially for...

This study shows for a large sample of R&D-active manufacturing firms that collaborative R&D has a positive effect on firms' patenting in terms of both quantity and quality. When distinguishing between alliances that aim at joint creation of new knowledge and alliances that aim at exchange of...

This paper tests a number of hypotheses on the use and effectiveness of patents and trade secrets designed to protect innovation. While previous studies have often considered patents and trade secrets as substitutes for one another, we investigate the complementary role of the two protection...

Successful innovative activity is a major contribution to the intangible capital of firms. Although its importance is generally acknowledged, the contribution to companies? profits is a priori unclear. We present the results of an empirical study on the effects of the patent stock on...

The present paper first discusses theoretically the different incentives of manager- versus owner-controlled firms for investment into innovative activity. In addition, the role of debt financing is analyzed. Subsequently the results from an empirical study on the determinants of innovative...

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...
