Jeffrey A. Miron is senior lecturer in economics at Harvard University. A Libertarian, he was one of 166 academic economists who signed a letter to congressional leaders last week opposing the government bailout plan.

Here is some excerpts from his take on the bailout:

This bailout was a terrible idea. Here's why.

The current mess would never have occurred in the absence of ill-conceived federal policies. The federal government chartered Fannie Mae in 1938 and Freddie Mac in 1970; these two mortgage lending institutions are at the center of the crisis. The government implicitly promised these institutions that it would make good on their debts, so Fannie and Freddie took on huge amounts of excessive risk.

Worse, beginning in 1977 and even more in the 1990s and the early part of this century, Congress pushed mortgage lenders and Fannie/Freddie to expand subprime lending. The industry was happy to oblige, given the implicit promise of federal backing, and subprime lending soared.

This subprime lending was more than a minor relaxation of existing credit guidelines. This lending was a wholesale abandonment of reasonable lending practices in which borrowers with poor credit characteristics got mortgages they were ill-equipped to handle.

Once housing prices declined and economic conditions worsened, defaults and delinquencies soared, leaving the industry holding large amounts of severely depreciated mortgage assets.

The fact that government bears such a huge responsibility for the current mess means any response should eliminate the conditions that created this situation in the first place, not attempt to fix bad government with more government.

The obvious alternative to a bailout is letting troubled financial institutions declare bankruptcy. Bankruptcy means that shareholders typically get wiped out and the creditors own the company.

Bankruptcy does not mean the company disappears; it is just owned by someone new (as has occurred with several airlines). Bankruptcy punishes those who took excessive risks while preserving those aspects of a businesses that remain profitable.

Further, the current credit freeze is likely due to Wall Street's hope of a bailout; bankers will not sell their lousy assets for 20 cents on the dollar if the government might pay 30, 50, or 80 cents.

Anticipation of the bailout will engender strategic behavior by Wall Street institutions as they shuffle their assets and position their balance sheets to maximize their take. The bailout will open the door to further federal meddling in financial markets.

So what should the government do? Eliminate those policies that generated the current mess. This means, at a general level, abandoning the goal of home ownership independent of ability to pay. This means, in particular, getting rid of Fannie Mae and Freddie Mac, along with policies like the Community Reinvestment Act that pressure banks into subprime lending.
