Economic Crisis is Crisis for Economic Theory

"Extremely preliminary and incomplete" Alan Kirman:

Thus the really basic issue, is that we continue in much of macroeconomic analysis to dismiss the aggregation problem and to treat economic aggregates as though they correspond to economic individuals although this is theoretically unjustified. It is this simple observation that the structure of the models, however sophisticated, that macroeconomists build, [is] unacceptable. But what is worse is that in the anxiety to preserve the scientific foundations, macroeconomists also dismiss the questioning of the soundness of the so-called scientific foundations.
