James Hamilton on the liquidity trap over at Econbrowser:
Some of my colleagues still talk of the possibility of a liquidity trap, in which the central bank supposedly has no power even to cause inflation. Their theory is that interest rates fall so low that when the Fed buys more T-bills, it has no effect on interest rates, and the cash the Fed creates with those T-bill purchases just sits idle in banks.
To which I say, pshaw! If the U.S. were ever to arrive at such a situation, here’s what I’d recommend. First, have the Federal Reserve buy up the entire outstanding debt of the U.S. Treasury, which it can do easily enough by just creating new dollars to pay for the Treasury securities. No need to worry about those burdens on future taxpayers now! Then buy up all the commercial paper anybody cares to issue. Bye-bye credit crunch! In fact, you might as well buy up all the equities on the Tokyo Stock Exchange. Fix that nasty trade deficit while we’re at it! Print an arbitrarily large quantity of money with which you’re allowed to buy whatever you like at fixed nominal prices, and the sky’s the limit on what you might set out to do.
Of course, the reason I don’t advocate such policies is that they would cause a wee bit of inflation. It’s ridiculous to think that people would continue to sell these claims against real assets at a fixed exchange rate against dollar bills when we’re flooding the market with a tsunami of newly created dollars. But if inflation is what you want, put me in charge of the Federal Reserve and believe me, I can give you some inflation.
