Revisiting incremental product innovations in the food manufacturing industry: An empirical study on the effect of intellectual property rights

Yoshioka-Kobayashi, Tohru: Tomofumi Miyanoshita: Daisuke Kanama
『Journal of Economic Structures』 (2020/04/20)

The highly competitive and mature food industry has long been process innovation-oriented while largely neglecting product/technological innovation. However, recent innovation debates have raised two issues. First, imitations of product innovations likely underestimate the value of innovation in this industry; second, exaggerations of …

                Management of science, serendipity, and research performance: Evidence from a survey of scientists in Japan and the U.S.

                Murayama, Kota: Makoto Nirei: Hiroshi Shimizu
                『Research Policy』 Vol.44 No.4 pp.862-873 (2015/05/01)

                In science, research teams are increasing in size, which suggests that science is becoming more organisational. This paper aims to empirically investigate the effects of the division of labour in management and science on serendipity, which has been considered one of the great factors in science. Specifically, in examining the survey o…

                    Patents and Cumulative Innovation:Causal Evidence from the Courts

                    Galasso, Alberto : Mark Schankerman
                    WP#13-16 Hitotsubashi University IIR (2013/08/20)

                    Cumulative innovation is central to economic growth. Do patent rights facilitate or impede such follow-on innovation? This paper studies the causal effect of removing patent protection through court invalidation on subsequent research related to the focal patent, as measured by later citations. We exploit random allocation of judges a…

                      WP#13-13 Hitotsubashi University IIR (2013/05/13)

                      This study investigates the impact of management style on research performance in science. If a managerial role is played by a leading scientist in the research team, that is considered management-research integration. If not, we consider that management and research are separated. We found that separating the managerial and research r…

                          WP#13-02 Hitotsubashi University IIR (2013/01/15)

                          How to design and manage a research team has become an increasingly important issue in knowledge creation in science. This paper aims to understand how young scholars contribute to scientific research in the context of a research team. We have found that the likelihood of the involvement of postdoctoral fellows is high in research team…
