I can usually pick up on an underlying problem, even if it's not too obvious. I recall an investment banker who visited our real-estate-finance class and asked us what might cause the Tokyo investment community a problem in attracting local investment dollars. A number of finance students in the class started trying to think of some complicated set of reasons. I decided it would have to do with getting out of a bad market quickly, and that a non-liquid investment would create problems. I said investors would be unsettled if the primary investment is local real estate and inflation has caused the paper value to exaggerate the real street value. As it ended up, that was the answer he wanted.
