Using the Difference In Difference methodology during the Spanish flu pandemic, the study carefully examines how joint application activities were inhibited by the pandemic.
This is the first empirical study in Japan we developed based on the long-term, since the Meiji period, patent data. The study provides valuable insights useful for studies on the effect of the COVID-19 situation. I feel very honored to be added to the list of co-authors of this Dr’Nakajima’s outstanding study.
