WP#17-14 Hitotsubashi University IIR (2017/08/28)

By exploring the technological development of laser diodes in the US and Japan, this study examines how the existence or absence of an entrepreneurial strategic choice for spin-outs influences patterns of subsequent technological development. The results show that spin-outs could hinder the subsequent development of existing technology…

          The merger paradox in Cournot oligopoly is revisited in the presence of R&D investment. Two cases are presented in which firms merge profitably without satisfying the 80-percent threshold requirement of Salant et al. (1983).

              WP#16-09 Hitotsubashi University IIR (2016/08/19)

              In the United States, brand-name drug manufacturers often pay generic companies to delay marketing of their generic products. In this paper we develop an analytical framework to examine the implications of banning reverse payment settlements. We first find that reverse payment settlements occur when generic firms face relatively high e…

                The measurement of scope economies using multi-product composite cost function

                Konno, Yukiko
                WP#16-05 Hitotsubashi University IIR (2016/04/08)

                This study employs a multi-product composite cost function to examine whether the major Japanese general contractors obtain scope economies by diversification. The analysis results indicate that the contractors do not obtain scope economies by the sector and client diversification.

                  Facing generic competition, a brand-name drug company sometimes launches its own generic called an "authorized generic"(AG) through a third-party entity. If an authorized party transfers a substantial part of its profits to the brand-name drug company, the letter's total profit increases as a result and every branded drug that comes of…

                      WP#15-21 Hitotsubashi University IIR (2015/09/28)

                      The merger paradox is revisited in the presence of cost-reducing R&D in Cournot oligopoly. Two cases are found, in which merger is profitable without satisfying the 80-percent threshold requirement of Salant et al (1983).

                            In order to assess the disclosure function of the patent system, this study examined the impact of the pre-grant publication system introduced in the United States in 2000. Unlike earlier studies, the applicant (inventor) non-self-citations (excluding examiner citations) were used to track knowledge flow. The causal effects of disclosu…
