  • Message to Prospective Students

    We expect our students to have basic knowledge of high-school level math, including calculus and basic probability theory, because they are essential for studying economics. At the same time, economics is not just about math. It is not just about money, either. Economists study various social issues and evaluate the effects of policies. For instance, I am studying and how school lunch affects junior high students’ body weight, and it is economics, too!
