The New York Times / April 19, 2009 Economic View It May Be Time for the Fed to Go Negative By N. GREGORY MANKIW (Copyright 2009 The New York Times Company)
... Until recently, most economists relied on monetary policy. Recessions result from an insufficient demand for goods and services — and so, the thinking goes, our central bank can remedy this deficiency by cutting interest rates. Lower interest rates encourage households and businesses to borrow and spend. More spending means more demand for goods and services, which leads to greater employment for workers to meet that demand. The problem today, it seems, is that the Federal Reserve has done just about as much interest rate cutting as it can. Its target for the federal funds rate is about zero, so it has turned to other tools, such as buying longer-term debt securities, to get the economy going again. But the efficacy of those tools is uncertain, and there are risks associated with them. In many ways today, the Fed is in uncharted waters. So why shouldn’t the Fed just keep cutting interest rates? Why not lower the target interest rate to, say, negative 3 percent? At that interest rate, you could borrow and spend $100 and repay $97 next year. This opportunity would surely generate more borrowing and aggregate demand. The problem with negative interest rates, however, is quickly apparent: nobody would lend on those terms. Rather than giving your money to a borrower who promises a negative return, it would be better to stick the cash in your mattress. Because holding money promises a return of exactly zero, lenders cannot offer less. Unless, that is, we figure out a way to make holding money less attractive. At one of my recent Harvard seminars, a graduate student proposed a clever scheme to do exactly that. (I will let the student remain anonymous. In case he ever wants to pursue a career as a central banker, having his name associated with this idea probably won’t help.) 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. Of course, some people might decide that at those rates, they would rather spend the money — for example, by buying a new car. But because expanding aggregate demand is precisely the goal of the interest rate cut, such an incentive isn’t a flaw — it’s a benefit. [Wait a sec, Greg! most money -- as usually defined -- is not currency. Most of it is entries in account books representing obligations of banks, i.e., their promises to allow us to access our checking accounts at a moment's notice and our savings accounts after a small delay. This program only encourages people to shun currency, not money. It encourages banks to shun vault cash, but not other reserves (deposits in the Fed) or quasi-reserves (T-bills). I'm quite surprised that a Harvard economist could fall for this confusion. ] The idea of making money earn a negative return is not entirely new. In the late 19th century, the German economist Silvio Gesell argued for a tax on holding money. He was concerned that during times of financial stress, people hoard money rather than lend it. John Maynard Keynes approvingly cited the idea of a carrying tax on money. With banks now holding substantial excess reserves, Gesell’s concern about cash hoarding suddenly seems very modern. [We could impose a tax on holding of _all_ money including the bookkeeping money discussed above.] If all of this seems too outlandish, there is a more prosaic way of obtaining negative interest rates: through inflation. Suppose that, looking ahead, the Fed commits itself to producing significant inflation. In this case, while nominal interest rates could remain at zero, real interest rates — interest rates measured in purchasing power — could become negative. If people were confident that they could repay their zero-interest loans in devalued dollars, they would have significant incentive to borrow and spend. Having the central bank embrace inflation would shock economists and Fed watchers who view price stability as the foremost goal of monetary policy. But there are worse things than inflation. And guess what? We have them today. A little more inflation might be preferable to rising unemployment or a series of fiscal measures that pile on debt bequeathed to future generations.... [By the way, this is _exactly_ what Krugman proposed for Japan during the 1990s. Did Mankiw ever hear about that? [It's interesting that Mankiw is ignoring the foreign exchange-rate impact of this policy. It may have made sense to drive the Yen down relative to other currencies during the 1990s, but does Mankiw want to do the same to the US$ now? Might not the greenback find its international reserve status undermined? If Mankiw's Krugmaniac policy is instituted, it would work best if major US trading partners pursue a similar policy.] [In the end, the fact that a conservative like Mankiw is going pretty radical is a sign of how much trouble capitalism is in.] -- Jim Devine / "Segui il tuo corso, e lascia dir le genti."
