Tatsuo Tanaka

Executive Research Fellow
Bachelor of Economics

■Research Area
Copyright, Personal Information, Content Industry, Platform Industry, Internet and Democracy

My research fields are seemingly disparate, but I am quantitatively investigating the impact of digitization on the economy and society. To make it easier to understand my background, let me summarize conclusions of my research. “As for Copyright? -> Loosen up, look at my latest paper, ‘The ultimate copyright system that I have thought up’ “, “Personal information? -> There is a good way to protect and use it at the same time, come and see me. “Entertainment industry? -> Giving contents away for free is a good way to make money”, “Platform industry? -> They are already big, so let’s think about everyone else’s needs”, “Internet and democracy? -> People say the Internet is dividing society, but don’t worry, the Internet will make society better! I have some good ideas.” Please feel free to contact me if you would like to hear more on the above. Have paper – will travel
