The purpose of this travel was to present my research at the 2026 North American Summer Meeting of the Econometric Society in Atlanta, Georgia, and to visit Stony Brook University, where I completed my Ph.D., for research discussions with my former advisors and collaborators. Through these activities, I aimed to receive feedback on my current research, strengthen my international research network, and develop future collaborative projects in economics. I traveled to the United States from May 17 to June 11, 2026.
From May 18 to June 3, I stayed at the Department of Economics, Stony Brook University, as a visiting faculty member, hosted by Prof. Steven Stern and Prof. Ting Liu. During this period, I held a series of research meetings with them to advance our ongoing collaborative work, discussing the formulation of our theoretical model, the identification strategy, and the overall structure of our co-authored paper. The visit was particularly meaningful because both professors have continued to provide important guidance for my research since my Ph.D., and meeting in person allowed us to work through revisions, future submission plans, and possible new directions in far greater depth than would have been possible online. I also benefited greatly from interacting with other faculty members and graduate students and from the department’s active seminar culture, which helped sharpen my own thinking.
From June 4 to June 7, I participated in the 2026 North American Summer Meeting of the Econometric Society, held at Emory University in Atlanta. The Econometric Society meetings are among the most important international conferences in economics, bringing together researchers across econometrics, microeconomic theory, industrial organization, labor economics, and applied microeconomics. I presented my paper, “Equilibrium Comparative Statics as Identification: Spousal Caring in a Household Biform Game,” which develops a framework to estimate a continuous degree of cooperation within households rather than treating cooperation as a binary assumption. I received valuable comments on the theoretical model, the identification strategy, and the framing of the paper. In particular, Prof. Vijay Krishna and other researchers encouraged me to connect my comparative-statics argument to a broader literature on identification and equilibrium restrictions in economics. This was an especially constructive exchange, and we have continued to correspond since the conference.
The meeting also provided numerous opportunities for informal discussion. I exchanged views with researchers from a range of fields, including microeconomic theory, applied microeconomics, and econometrics, and was able to build new international connections. In addition, I met with my co-author, Prof. Sofia Ruiz Palazuelos, to discuss a separate ongoing project. Through our discussions, we identified concrete points for revising that paper and clarified our plan for future submission.
On June 8, I returned to Stony Brook University and continued my stay until June 10, holding further research meetings with Prof. Stern and Prof. Liu to consolidate the progress we had made and to plan
the next steps of our collaboration. I departed New York on June 10 and returned to Tokyo on June 11.
This travel provided an extremely valuable opportunity to combine international conference participation with intensive research meetings at a leading U.S. university. I was able to present my work to an international audience, receive constructive feedback, continue productive discussions with my academic mentors and collaborators, and strengthen my professional network in the United States. These experiences will directly contribute to the development of my current papers and to my broader research agenda as an early-career scholar.
I am deeply grateful to Friends of UTokyo, the FUTI Travel Award Committee, and their supporters for their generous support, which made this research travel possible.
