Social Science Seminar

ProfessorISHIKAWA, Jota

Economics is a kind of grammar of economy. In the case of language, you can speak to some extent without understanding the correct grammar, but grammar is essential for speaking accurately and writing logical sentences. Similarly, you can live without knowing economics, but without knowledge of economics, you cannot accurately understand and logically explain how economy works. Not all knowledge of economics may be immediately useful, but economic thinking and perspectives will help us survive a rapidly changing economy.

Graduation Thesis

My classes aim to let students know the fun of economics, focusing on its perspectives and ways of thinking, and at the same time, enable them to organize, understand, and analyze various economic issues on their own. In "Introduction to the Global Economy" and "Japan in the World Economy," students will broaden their knowledge of both Japanese and world economies by examining international economic dependencies. "Game theory" and "Industrial Organization" consider the movements and formation of the society by analyzing the interdependence of the various actions and decision-making of economic agents.

Seminar

The university is a place for independent learning. In the seminar class, the supervisor is just a support role. The seminar class is just like a "dojo," where students learn various things on their own and cultivate an attitude of carving out paths on their own with the help of the supervisor. My seminar class places particular emphasis on "strategic thinking," "utilization of data," and "audience-friendly presentation."

Research content

What kind of economic policies should countries adopt as globalization progresses and international dependence deepens? The field of international economics provides the knowledge necessary to answer this question. In that field, I mainly conduct research on international trade theory dealing with cross-border movements of goods and services. For example, my research interests include non-tariff barriers that hinder free trade by means other than tariffs, and cross-border economic activities by multinational enterprises. I have also studied how trade and trade policies affect the environment, and how environmental policies such as countermeasures against global warming affect trade. Recently, I am also interested in the effects of the progress of digital economy.
