Pourquoi n’a-t-on rien vu venir ? La mise en cause des économistes face à la crise financière

The international financial crisis of 2007-2010 occurred in the historical context of a deregulated financial capitalism. The combination of a wave of financial innovations and not controlled macroeconomic disequilibrium allowed a generalized debt burden leading to the rise of systemic risk. By their works and appraisals, the economists contributed to legitimate the risked innovations and to underestimate the macroeconomic disequilibrium. Therefore it is urgent to renew the research agenda of the economists and especially to rehabilitate the Keynes’s heritage.
