Alternative sources of technology: An analysis of induced innovations

This paper considers why firms differ in the degree to which they rely on their internal R&D organization for generating new technologies (induced innovations) rather than on existing external technology markets (purchased innovations). An empirical model is suggested to explan inter-firm differences in the percentage of new technology induced through R&D efforts. The analysis suggests that such differences are systematically related to the firm's size, its competative environment, and its degree of diversification.     

Entrepreneurship and knowledge spillovers from the public sector

A compelling body of research has found that investments in knowledge from other firms and universities spill over to enhance the performance of entrepreneurial firms. This literature has shown that firm performance is positively related to investments in new knowledge by other firms and research universities. This paper addresses a gap in the literature by positing that public sector knowledge is also conducive to enhancing performance by knowledge intensive entrepreneurial (KIE) firms. Our findings suggest that the public sector provides a fertile source of knowledge for enhancing KIE firm performance.

     

Scientific and Commercial Incentives in R&D: Research versus Development?

This paper proposes a framework to analyze the effects of scientific and commercial incentives in R&D organizations. We build a simple repeated model of a researcher capable of obtaining innovative ideas. Although they reduce the time spent on research, we show that commercialization incentives also affect the choice of research projects. Commercial rewards induce a more intensive search for (ex post) path-breaking innovations, which are more likely to be generated through (ex ante) riskier research programs. We derive the organization's optimal incentive scheme in terms of the researcher's characteristics. We show that organizations should use a high level of commercial incentives for scientists who have strong or weak intrinsic preferences for research. For those with strong preferences, the organization needs to induce development, whereas for those with weak ones, it needs to induce effort.     

Investment in Africa's Manufacturing Sector: A Four Country Panel Data Analysis

Firm level data for the manufacturing sector in Africa, presented in this paper, shows very low levels of investment. The importance of profit effects on investment is investigated using a flexible accelerator, a specification based on the Euler equation and a simple generalisation of these specificiations. There are controls for firm fixed effects. It is shown that the profit effect is very similar for both the accelerator and Euler equation specifications. A comparison with other studies shows that, for small firms, the effect is much smaller in Africa than for other countries. Reasons for the relative insensitivity of investment to profits in African firms are suggested. For the most general specification tested there are no significant differences in the size of the profit effect across the four countries in the study.
