Effects of early patent publication on knowledge dissemination: Evidence from U.S. patent law reform

Okada, Yoshimi :Sadao Nagaoka
『Information Economics and Policy』 （2020/01/25）

In order to assess effects of early publication of patent applications on the dissemination of the disclosed technological knowledge, this study examines the impacts of the 18-month pre-grant publication system introduced in the United States in 2000. It focuses on the variations of the applicant non-self-citations driven by the actual…

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…

No. 654 IDE Discussion Papers （2017/04/01）

Many countries are interested in strengthening their technological capabilities to achieve high growth rates. Knowledge flow is a key to build technological capabilities…

Mobility of Highly Skilled Retirees from Japan to the Republic of Korea and Taiwan

Kang, Byeongwoo : Yukihito Sato : Yasushi Ueki
ERIA Discussion Paper 2016-31 Economic Research Institute for ASEAN and East Asia （2017/02/28）

Attracting highly skilled workers is a major element in the economic development of many countries, especially developing ones. However, workers generally move from developing countries to developed ones. Historical evidence indicates that Korean and Taiwanese firms scout for highly skilled (retired or soon-to-retire) Japanese workers …

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.

Testing for localization: A new approach

Murata, Yasusada : Ryo Nakajima : Ryuichi Tamura
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…
