Lawrence Summers :
Famously, while you can fool all of the people some of the time and some of the people all of the time, you cannot fool all of the people all of the time. In the same way, markets may well be inefficient and diverge from fundamental value, and they may well be subject to government manipulation for significant intervals, but it is a foolish government that supposes it can indefinitely maintain speculative prices at politically convenient levels, as the Chinese authorities may soon discover.
