Usually, cooperation in Prisoner's Dilemma (PD) is regarded as problematic or paradoxical. Cooperation is explainable in the iterative version of PD,  in the form of reputation building, and nice, retaliatory and forgiving strategies. But even then respect for selfish defection is in the air.

But in the financial market situation, cooperation seems to be prevailing - market participants wish to cooperate as long as possible. "Cooperation" is based on something different than usual iteration - is it a wonder of so wide manipulation, or we still have to learn PD better? It seems that market failure is clearly unacceptable to anyone, so people try to hold on to hopes. That may explain why it is difficult to time financial collapses in advance.
