About 27 years ago, when I was a junior scholar, I gave a talk at the Massachusetts Institute of Technology. Professor Oliver Hart attended the seminar and asked me many tough questions. For me, it was valuable on-the-job training. Even with his renowned achievements and contributions to society, Hart today still attends a lot of seminars as an ordinary participant.
Professor Bengt Holmstrom also inspired me with his unique insights. He invited me to a seminar when he was teaching at the Yale School of Management and helped me publish one of my academic works, which was related to his work, by giving me valuable advice.
