    Technology standards are considered important tools for increasing bargaining power and licensing revenues by combining the strategies of firms with the standard-setting organizations (SSOs) standardization processes. The essential patents declared by members of the SSOs play a critical role in such standardization processes. Some former researchers have found that, when using network analysis for measuring the knowledge positions in the “main-path” of standards-based markets, the essential patents did not match very well with the actual knowledge positions of the firms, in most cases. In this paper, we focus on the essential patents declared by the member firms in JTC1, an SSO that provides a standards development environment related to the development of the worldwide information and communication technology (ICT) standards for business and consumer applications, and that employs social network analysis techniques to investigate the knowledge positions of the patents, not only in the “main-path” discussed in the earlier literature, but also in the brokerage processes. We found that the brokerage-process approach helped us to better understand the roles of the essential patents that dominate transactions, relations, and the exchange of knowledge in the patent citation network than that of the main-path. Our findings suggest that claiming essentiality depends on the strategic behavior not only of the patents’ owners, but also of the SSOs.

    This article studies the effects of international and intranational knowledge flows. Contributions include comparing the effects of knowledge flows on the formal and informal sectors and determining multilateral spatial spillovers of innovation. Results show that formal entrepreneurs respect intranational intellectual property rights, but benefit from international spillovers, especially from patents granted. In contrast, informal entrepreneurs somewhat respect intranational patents granted, but not patent applications and citations. International spillovers to the informal sector are mainly from patents granted. Spillover magnitudes are greater internationally than intranationally, and greater in the informal sector than the formal sector (except for trademarks). (JEL O33, L26, K42)

  • Trade patterns and international technology spillovers: evidence from patent citations 査読

    In this paper, we empirically examine the relationship between bilateral trade patterns and international technology spillovers for a sample of 55 countries during 1995-2006. Technology spillovers are measured by using patent citation data taken from the United States Patent and Trademark Office. The main contribution of this paper is to provide new evidence that the size of technology spillovers significantly varies according to bilateral trade patterns. In particular, horizontal intra-industry trade is associated with larger technology spillovers than vertical intra-industry trade, and the size of technology spillovers is smallest when the trade pattern is inter-industry trade. Given the fact that trade between technologically advanced countries has a higher share of horizontal intra-industry trade than trade between other combinations of countries, our findings suggest that trade may enlarge, rather than narrow, the technology gap between technologically advanced and less-advanced countries.

  • Innovation and underground entrepreneurship 査読

    This paper examines the impact of innovation on the underground economy, focusing on differences between informal entrepreneurship and the overall shadow economy. Using cross-national data and measuring innovative activity alternately by patent grants and patent applications, results show that increases in innovative activity spur informal entrepreneurship. The effects of innovation on the overall shadow economy are insignificant. Further, general improvements in government effectiveness seem more effective in checking the underground sector than specific initiatives related to minimum wages or taxes. Transition countries, ceteris paribus, have lower informal entrepreneurship, but higher overall underground economy.

  • International Knowledge Flows and Productivity: Intra- vs. Inter-Industry Spillovers 査読

    Abstract: The effects of international knowledge spillovers on total factor productivity (TFP) at the industry level are examined by using a panel of 13 manufacturing industries across 15 OECD countries over 23 years. We distinguish between intra- and inter-industry spillovers from the information on patent applications and citations. Patent data are taken from the Japan Patent Office and the United States Patent and Trademark Office. Using four alternative spatial panel estimation techniques, we find that international knowledge spillovers within the same industry significantly contribute to sectoral TFP. In contrast, there is little evidence of a positive effect of international knowledge spillovers on TFP across industries.

  • Gender dynamics and smoking prevalence in Japan 査読

    Using recently available data spanning four decades, this paper examines the determinants of smoking prevalence in Japan. Main contributions include (i) examining differences across demographics
    (ii) studying the effect of intra-household spousal economic power on smoking
    and (iii) providing evidence on the efficacy of the Framework Convention on Tobacco Control (FCTC). Results show that higher cigarette prices are more effective at reducing smoking prevalence among males than females, with significant differences across age groups. Greater economic prosperity and FCTC also deter male smoking, as does a higher relative income share of the wife in the household. © 2012 © Springer Science+Business Media, LLC (outside the USA) 2012.

  • Why do Japanese companies file patents in China? Revisited 査読

    Purpose: The purpose of this paper is to revisit the Chinese patent application upsurge among Japanese MNEs. Design/methodology/approach: The authors extended the sample provided by Nakata and Zhang, from the period of 1995 and 2003 to 1995 and 2007, and paid more attention to the market advantage of Japanese MNEs and competitive relationships such as those between Japanese MNEs and domestic as well as other foreign firms in China. Findings: The present findings indicated that after China revised its patent law for the second time and joined the WTO, patenting by Japanese MNEs became increasingly driven by those that operated diversified businesses in China. Competition in IPR measured by the technology proximity of Japanese MNEs with domestic as well as other foreign firms showed a positive correlation with regard to increased patenting. Originality/value: To the best of the authors' knowledge, this is the first paper that focused on the effects of Chinese IPR reform on the Chinese patenting behavior by Japanese MNEs. © Emerald Group Publishing Limited.

    Our research on patent filing in Japan identified major determinants of the time between application filing and the lodging of an examination request, and considered the influence of two factors on requests: patent value indices, as well as patent filing and innovation strategies. Our sample covered patent applications of 214 listed Japanese electrical and electronics manufacturers during 1988-2001. The empirical results show that, in the early 1990s, large firms and those with high R&amp
    D intensity and patent propensity tended to delay requests
    in the late 1990s, their requests accelerated, with those for applications likely to be granted being lodged earlier. Meanwhile, such patent value indices as degree of originality, number of self-citations and external citations had a positive correlation to early examination requests for most periods covered in the sample
    joint application and generality showed mixed effects
    and such time-varying factors as competitive filings produced diverse results. © 2012 Copyright Taylor and Francis Group, LLC.

    In this paper, we examine international technology diffusion by using patent citations as a proxy for technology diffusion. We focus on some Asian economies, i. e., Korea, Taiwan, China and India, to investigate the relationship between technology diffusion and their trade experience with the U. S., Japan, and other G7 countries. Our empirical results reveal that trade specialization has a significant correlation with technology diffusion. Some policy implications are discussed. © 2009 Springer Science+Business Media, LLC.
