    Specialization / Quantitative Macroeconomic Analysis

I obtained my PhD in Economics from the University of California, Los Angeles (UCLA). After working at the Institute for Monetary and Economic Studies at the Bank of Japan for two years, I taught at Sophia University's Faculty of Liberal Arts for two years and at the University of Kent in the UK for seven years. Since 2017, I have held my current position at the ÎçÒ¹¾ç³¡ Faculty of Business and Commerce. Moving between various workplaces unexpectedly has blessed me with opportunities to interact with many different researchers.

Research activity is an important duty for university faculty. This is an essential task for reflecting the rapid progress of academic research in higher education. My field of research is called "Quantitative Macroeconomic Analysis," which uses economic models that simplify the real economy to its necessary minimum to perform factor analysis of macroeconomic phenomena such as economic growth and business cycles, and to estimate policy effects.

The research I am currently focusing on is the analysis of the impact of aging on the economy. In Japan, which has become a super-aging society at a speed unparalleled in the world, it is an extremely important task to clarify to what extent various economic policies can mitigate the negative effects that aging has on economic growth through a shrinking labor force and increasing social security burdens.

These research results are published in the form of academic papers, but the impact of the paper itself and the evaluation of the researcher depend on which academic journals they can be published in. Economists hope that the real economy will be improved by the findings they discover. Therefore, we work hard every day to have our papers accepted by prestigious journals that can be seen by more people.

Papers on quantitative macroeconomic analysis generally consist of economic trend analysis based on macroeconomic data, the construction of macroeconomic theoretical models, and quantitative analysis using those models. Therefore, by having multiple co-authors specialize and divide tasks into areas they are relatively good at¡ªsuch as data analysis, economic theory, or programming¡ªwe can efficiently produce high-quality research results. This is a concept called "comparative advantage" in economics.

I myself conduct joint research with excellent researchers, such as my former mentors and classmates from UCLA, former bosses and colleagues from the Bank of Japan, friends I met at Sophia University, and former colleagues from the University of Kent. In order to continue solving important research issues, I will cherish my connections with people and look forward to being blessed with new encounters.
