Barry Eichengreen, the pre-eminent historian of the international monetary system, delivers a withering retort to those who urge inaction in the face of financial crisis:
inflicting intense pain upon innocent bystanders through a long period of high unemployment is not the best way of discouraging irrational exuberance in financial markets. Nor is precipitating a depression the most expeditious way of cleansing bank and corporate balance sheets. Better is to stabilize the level of economic activity and encourage the strong expansion of the economy. This enables banks and firms to grow out from under their bad debts. In this way, the mistaken investments of the past eventually become inconsequential. While there may indeed be a problem of moral hazard, it is best left for the future, when it can be addressed by imposing more rigorous regulatory restraints on the banking and financial systems.
