  • Spin-Outs and Patterns of Subsequent Innovation: Technological Development of Laser Diodes in the US and Japan

    Shimizu, Hiroshi : Naohiko Wakutsu
    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 expanding Empire and spatial distribution of economic activity: the case of Japan's colonization of Korea during the prewar period

      Nakajima, Kentaro : Tetsuji Okazaki
      『The Economic History Review』 Vol.71 No.2 pp. 593-616 (2017/06/09)

      In 1910, Japan annexed Korea and integrated it into the Empire of Japan. According to its policy of assimilating colonies, the Japanese government intended to remove the tariffs between Japan and Korea, an aim which had almost been realized by 1923. The removal of the tariff barrier was supposed to improve market access between Japan a…

          • Did China’s Coal Mine Regulation Positively Affect Economic Growth?

            Xu, Hangtian : Kentaro Nakajima
            『Resources Policy』 Vol.50 pp. 160-168 (2016/12/01)

            In response to high mortality rates and low productivity in coal mining, China began regulating coal mines in the 1990s, reshaping its coal economy. We investigate the relationship between coal mine regulation and economic growth. Using the difference-in-difference approach to compare the pre- and post-regulation periods as well as reg…

              Kawata, Keisuke : Kentaro Nakajima : Yasuhiro Sato
              『Regional Science and Urban Economics』 Vol.61 pp. 114-129 (2016/11/01)

              We develop a competitive search model involving multiple regions, geographically mobile workers, and moving costs. Equilibrium mobility patterns are analyzed and characterized, and the results indicate that shocks to a particular region, such as a productivity shock, can propagate to other regions through workers' mobility. Moreover, e…

                  Innovation and the Merger Paradox

                  Miyagiwa, Kaz: Yunyun (Jiangyun) Wan
                  『Economics Letters』 Volume 147 October 2016 pp. 5-7 (2016/10/01)

                  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.

                          WP#16-01 Hitotsubashi University IIR (2016/01/13)

                          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…

                              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…
