    Environmental regulation and international expansion of MNEs: The moderating role of pollution reduction resources and firm multinationality on location choice

    Malen, Joel : Junichi Yamanoi
    WP#16-13 Hitotsubashi University IIR (2016/12/07)

    We examine how stronger environmental regulations influence MNE international expansion decisions by attending to two sources of firm heterogeneity that moderate this effect: possession of pollution reduction capabilities and firm multinationality. Empirical tests on 523 cases of international manufacturing expansion into 49 potential …

      Contribution of Patent Examination to Making the Patent Scope Consistent with the Invention: Evidence from Japan

      Okada, Yoshimi : Yusuke Naito : Sadao Nagaoka
      RIETI Discussion Paper 16-E-092 Research Institute of Economy, Trade and Industry (RIETI) (2016/11/29)

      Delineating the patent scope consistently with the contribution of the disclosed invention is one of the most crucial requirements for a patent system to promote innovation effectively. Given the incentive of an applicant to set a scope for the patent as broad as possible, an important task of the Patent Office is to narrow it so that …

      • Descriptive analysis of the knowledge network formation in East Asia

        Nabeshima, Kaoru : Byeongwoo Kang : Mila Kashcheeva
        『Technology in Society』 Vol.47 pp. 66-100 (2016/11/01)

        This paper shows descriptively how the knowledge network in East Asia has been formed. In addition, the correlation between the knowledge network and economic growth is also examined. Evidence is provided to show that plugging into the knowledge network of developed economies could be a key for increasing innovativeness in an economy.

            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).

              • Testing for localization: A new approach

                WP#16-11 Hitotsubashi University IIR (2016/08/19)

                Recent empirical studies document that knowledge spillovers attenuate and industry localization decays with distance. It is thus imperative to detect localization accurately especially at short distances. We propose a new approach to testing for localization that corrects the first-order bias at and near the boundary in existing method…

                  Reverse payments and generic entry competition

                  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…

                        WP#16-07 Hitotsubashi University IIR (2016/07/13)

                        We investigate the global spread of pharmaceutical patent protections as acquired by firms, based on a novel global patent database for all significant medical drugs introduced in Japan. It gives us the propensity of filing and grant rate for each country for the granted patents in Japan. Major findings are the following. Both the fili…

                            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.

                              Claim Length as a Value Predictor of a Patent

                              Okada, Yoshimi : Yusuke Naito : Sadao Nagaoka
                              WP#16-04 Hitotsubashi University IIR (2016/04/07)

                              The claim of a patent defines the scope of patent right and provides crucial information on patent value. However, most empirical research uses only the number of claims as an indicator of patent value. We show that the breadth of a claim of Japanese patents, measured by the inverse of claim length, has significant explanatory power fo…

                                  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…
