Ben Bernanke earned the sobriquet “Helicopter Ben” for his observations in a 2002 speech that “the U.S. government has a technology, called a printing press (or, today, its electronic equivalent), that allows it to produce as many U.S. dollars as it wishes at essentially no cost”, that the existence of this technology means that “sufficient injections of money will ultimately always reverse a deflation”, and that using this technology to finance a tax cut is “essentially equivalent to Milton Friedman’s famous “helicopter drop” of money.” But just because he’s called “Helicopter Ben” doesn’t mean that he knows how “Helicopter Money” would actually work.
His column “What tools does the Fed have left? Part 3: Helicopter money” discusses both the nuts and bolts of actually implementing a “Helicopter Drop” (or as he more accurately describes it, “an expansionary fiscal policy—an increase in public spending or a tax cut—financed by a permanent increase in the money stock”) and also discusses how such a policy might affect the real economy. While his discussion of the nuts and bolts is realistic, his discussion of how it would work is fantasy.

The nuts and bolts are straightforward (and Bernanke has a good practical suggestion for how to implement it too, which I’ll discuss at the end of this post). “Helicopter money” (or as he excitingly renames it, “a Money-Financed Fiscal Program, or MFFP”) is a direct injection of money from the government into people’s bank accounts, which is financed by a loan from the Federal Reserve to the Treasury. This differs from the standard way that Government spending is financed, which is by issuing Treasury Bonds that are then bought by the public.
The standard method doesn’t put additional money into circulation in the economy, because the increase in some private sector bank accounts caused by the government spending—a tax rebate, for example—is completely offset by the fall in other private sector bank accounts as they buy the Treasury Bonds that financed the tax rebate.
But with “MFFP”, the tax rebate is financed by new money created by the Federal Reserve “at essentially no cost”. It thus directly increases the money supply, and this is where Friedman’s “Helicopter” analogy comes from. In the private sector economy, the money supply is increased when private banks lend to the public. Money created by private bank lending also goes by the nickname of “inside money”, since it is created by institutions that are “inside” the private sector—private banks.
