Main Point:explain the SLE in Financial market----"rational irrational" aggregated the marketplace.
P1: explain what is SLE by the example of walk on Bridge
more people ----adjust to same pedestrians stride---sideways forces---bridge's swing
P2: there is also SLE happened in financial markets
Trade in orderly--- crisis---biggest player will reduce their exposure---then everybody moving in lockstep----just like people walk in the bridge--- then markets unstable
P3: example of argument in P2----Great Crunch
House Price falling----Mortgage bonds for Poor and Middle-income home delinquencies rising----banks pull back the credit lines----More and more banks did so----economy collapse
P4: Conclusion: what is truly caused the crisis?
---- not the false of bankers, not such easy but more scary reason.
---- caused by "rational irrational" behaviour: rational in individual level, but aggregated the market
