While GFPs are often justified by their domestic benefits, their international effects remain less clear. We posit that GFPs amplify international spillovers by signalling technological promise: government selection legitimises priority fields and attracts foreign attention. Using patent data from Japanese GFPs and a matched sample of private R&D, we find that GFPs' patents receive significantly more international forward citations, especially when projects are highlighted in

Drawing on multiple case studies of three Nordic multinational enterprises (MNEs) and their longstanding subsidiaries in Japan, the United States, and Western Europe, we develop a model of how institutionally derived enablers of subsidiary influence facilitate subsidiary avoidance of and involvement in headquarter strategy initiatives. We uncover how

Policies targeting emerging sectors like AI offer the groundwork for understanding policy directionality through how policy objectives and mechanisms evolve. The analytical framework employed includes policy objectives, level of implementation, and dynamics. The findings reveal that both countries follow similar stepwise approaches, but

We show that travel is frequently undertaken as part of a travel itinerary, defined as a journey starting and ending at home that can include more than one intermediate stop on a given day. We show that these travel itineraries provide microfoundations for consumption externalities and generate both complementarity and substitutability between locations. We

This study aims to quantitatively measure the impact of military technology development on civilian innovation activities using prewar and wartime Japanese patent data from 1916 to 1945. By exploiting Japan's secret patent system, which classified particularly critical military-related technologies not disclosed to the public, we identify important technological developments. The result shows

Influenced by its culture and social background, Japan’s AI governance policy focuses on promoting innovation, taking an agile, “soft-law approach” to governance, and emphasizing international interoperability of AI systems. The Japanese government recently strengthened its legal efforts regarding AI by introducing legislation in the Diet (parliament) at a time of dramatically shifting debate on global AI governance policies in 2025. With the

Using unique patent bibliographic data for this period, we estimate the pandemic’s impact on innovation in technologies requiring intensive human interaction for invention. Specifically, we define patent technology classes with large fractions of collaborative patents before the

Existing research has yielded contradictory conclusions between SSOs and firm innovation, engendering a complexity for both practitioners and academic researchers in thoroughly understanding this domain. This study investigates the influence of SSOs on solid innovation and moderating factors, such as network size, membership policy, and firm size. The dataset was collected from 339 firms of the HDMI
