Inflation Coming Soon

Wow. Greg Mankiw has written an unusually provocative argument in favor of inflation, even outright monetary destruction. Addressing the problem that the Fed can only push rates to zero, (and if that doesn't stimulate lending, what will?) he writes:

Imagine that the Fed were to announce that, a year from today, it would pick a digit from zero to 9 out of a hat. All currency with a serial number ending in that digit would no longer be legal tender. Suddenly, the expected return to holding currency would become negative 10 percent.

That move would free the Fed to cut interest rates below zero. People would be delighted to lend money at negative 3 percent, since losing 3 percent is better than losing 10.

I am shocked by how reckless his proposal is. Unbelievable. The way out of the financial collapse is to basically render useless one-tenth our money. (As Mankiw no doubt realizes, in practical terms this wouldn't work, since the overwhelming portion of the money supply is not attached to paper notes. Only about $800 bil of the money supply is paper currency, while M3, the broad measure of the money supply, is nearly $15 tril)

Imagine if stimulating the economy were as easy as Mankiw suggests. If destroying 10% of our money is this good, why not destroy 50%? Why not simply build immense fires and burn all our paper Federal Reserve notes that we call money? What a fantastic stimulus that would be.

Destroying money through inflation will not cause a stimulus of any kind, it will cause chaos. Inflation introduces distortions into the economy. Businesses cannot easily calculate future returns; inflation transfers money from worker to employer, from saver to borrower, from the poor who tend to be far away from the money-generating mechanism, to the wealthy and well-connected, who tend to be nearer to the source, and hence can spend their income before prices rise.

Because Greg Mankiw is a towering figure in the economics establishment (professor at Harvard, chair of the Council of Economic Advisors under Bush, influential blogger and textbook author), and because this interesting article appears in the NY Times, (where it is immediately heralded by Paul Krugman) I suggest that Mankiw is striking a chord that will resonate with the central banking and political establishment, which no doubt sees the logic of inflation.

Though the CPI indicates that deflation has been our recent history, that will not last under a determined attempt to produce inflation. Remember, the Fed can print money and drop it from Helicopters. The Fed can write the US government a check for a trillion dollars. (The Fed can even write me a check for a trillion dollars, but I'm afraid I will not stop blogging.) If the Fed wants inflation, the Fed will get inflation. Mankiw simply says what needs to be said to ease the way toward that inflation.

By the way, it is completely wrong to say that inflation will stimulate bank lending. Banks are extremely reluctant to lend under inflationary conditions, unless interest rates are fully flexible, indexed to inflation and all other relevant conditions. Does that sound familiar? That is what an adjustable rate mortgage is all about. But even if rates are fully adjustable, there are two additional problems:

1) what if raising the rate high enough to cover the bank and ensure that the loan is profitable destroys the borrower?

2) how many borrowers are willing to borrow with such uncertain costs of borrowing?

If inflation was such a reliable way to stimulate bank lending, Zimbabwe would've become the world's banker, instead of the world's most recent example of the failure of central banking.

Within a year, we'll see double-digit inflation rates.
