If you start bailing the firms out when they lose, you have to regulate the gambles they take. You can no longer count on the creditors to limit the firms' leverage, as the creditors are counting on Uncle Sam if things go wrong. But the more regulated these firms are, the lower their productivity will be.
The bottom line: The Bear Stearns bailout may have saved the economy from an episode of financial contagion in the short run, but in the long run it will likely leave us with a more regulated and less vibrant financial system.
My Comments: Bear Stearns should have been allowed to fail.
