  • An Economic Analysis of Deferred Examination System: Evidence from Policy Reforms in Japan

    Yamauchi, Isamu : Sadao Nagaoka
    WP#14-05 Hitotsubashi University IIR (2014/06/26)

    We investigate how a deferred patent examination system promotes ex-ante screening of patent applications, which reduces both the number of granted patents and the use of economic resources for examinations, without reducing the return from R&D. Based on a real option theory, we develop a model of examination request behaviors. Exploit…

                  In Japan, as in many developed countries, the government's agencies for science have implemented several reforms to the scienti c research system, which has concentrated research resources in the top research universities. However, the growth of research papers has stagnated in Japan during the 2000s. To analyze the reason for this, th…

                          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…

                              The US government criticized Japanese environmental policies, which promoted eco-friendly car (eco-car) purchases via measures such as tax exemptions and subsidies, as disguised forms of protection by arguing that the fuel economy standard for the subsidy qualification was designed to be more beneficial to domestic firms.
