Joseph Stiglitz reviews past and present global fiscal and monetary crises for a common thread and found that
financial sectors behaved badly and failed to assess creditworthiness and manage risk as they were supposed to do.The New York Fed has done some research and found that speculators ramped up values and lenders were a party to this inflation.
We conclude that investors were much more important in the housing boom and bust during the 2000s than previously thought. The availability of low- and no-down-payment mortgages in the nonprime sector enabled investors to make these bets..
..We conclude that it’s very important for lenders (and regulators) to manage leverage as asset bubbles are inflating.
..Effective regulation of speculative borrowing, like what is being attempted in China today, may be needed to prevent this kind of crisis from recurring.It has becoming obvious that self regulation is the flaw.
