You know you will not be able to understand some big guys' speech, but you still want to torture yourself and see them. That's exactly what I did last night for Tirole. Well, not until last night had I realized how bad my micro foundation was and how poor my knowledge of finance was.

It was one of the "Barcelona GSE Lecture Series", and

Prof. Jean Tirole (Toulouse School of Economics)

"Regulating systemic risk"

Hence, with the words "risk" and "regulation", you can imagine what he was talking about. I knew so little about finance, and then it became a disaster for me to stay there. In contrast, a friend who sat besides me was really enjoying the lecture and benefited a lot - he is a Ph.D in Econ/Finance. That's fair~

Anyway, it is a little out of my initial expectation but fair, that in UPF, the traditional Macro school, I have touched more macro compared to micro, although I was so interested in micro. Maybe it is a good thing that I do not need to close myself within a narrow room. Who knows? You can never go back and do something different. Whatever I have archived, I appreciate.
