Open Market Operations in Equities

UCLA economist Roger Farmer suggests the Fed buy some stock:

So where do we go from here? The only actor large enough to restore confidence in the US market is the US government. The current policy of quantitative easing by the Fed is a move in the right direction but it does not, as yet, go nearly far enough.

It is time for a greatly increased role for monetary policy through direct intervention of central banks in world stock markets to prevent bubbles and crashes. Central banks control interest rates by buying and selling securities on the open market.

A logical extension of this idea is to pick an indexed basket of securities: one candidate in the US might be the S&P 500, and to control its price by buying and selling blocks of shares on the open market.

Even the credible announcement that a policy of this kind was being considered should be enough to boost the markets and restore consumer and investor confidence in the real economy.

Critics will argue that this policy is dangerous socialist meddling. But I am not arguing that the government should pick winners and losers: only that it should stabilise a broad
basket of stocks. This policy would still allow poorly run firms to fail but it would not allow all firms to fail at the same time.

I believe that James Tobin suggested something similar many years ago.
