In the midst of the current Keynesian fervor, we would do well to remember the work of the man who predicted the Great Depression, Ludwig von Mises. His theories just so happen to apply to recent financial crisis as well, but that doesn't mean more people are heeding his wisdom. Hopefully those managing things will wake up and take note:

Taking his cue from David Hume and David Ricardo, Mises explained how the banking system was endowed with the singular ability to expand credit and with it the money supply, and how this was magnified by government intervention. Left alone, interest rates would adjust such that only the amount of credit would be used as is voluntarily supplied and demanded. But when credit is force-fed beyond that (call it a credit gavage), grotesque things start to happen.

Government-imposed expansion of bank credit distorts our "time preferences," or our desire for saving versus consumption. Government-imposed interest rates artificially below rates demanded by savers leads to increased borrowing and capital investment beyond what savers will provide. This causes temporarily higher employment, wages and consumption.

Ordinarily, any random spikes in credit would be quickly absorbed by the system—the pricing errors corrected, the half-baked investments liquidated, like a supple tree yielding to the wind and then returning. But when the government holds rates artificially low in order to feed ever higher capital investment in otherwise unsound, unsustainable businesses, it creates the conditions for a crash. Everyone looks smart for a while, but eventually the whole monstrosity collapses under its own weight through a credit contraction or, worse, a banking collapse.

The system is dramatically susceptible to errors, both on the policy side and on the entrepreneurial side. Government expansion of credit takes a system otherwise capable of adjustment and resilience and transforms it into one with tremendous cyclical volatility.
