I saw Shiller speak awhile back and
like Felix I was quite puzzled by his desire to fix things buy adding even more financial "innovation." One proposal involved insurance against falling home prices, which just seemed to be kind of absurd. The whole game seems to involve injecting as much risk into the system and then conning or forcing the suckers to pay to remove it again. Oh, and then repackaging that risk and conning still more suckers into buying it.
