The most recent headlines on this topic have centred around Japan. As the Bank of Japan approaches practical limits on its purchase of government bonds, several economists have argued that it might be time to consider helicopter money.
Simply put, helicopter money is a direct transfer of money to raise inflation and output in an economy running substantially below potential. Thus far, conventional QE has not achieved Japan’s 2% inflation target.
According to a paper by the St. Louis Fed, this could be due to expectations that it would eventually be unwound, diminishing the policy’s credibility. Since helicopter money is free and never has to be repaid, this approach may have a better shot at achieving Japan’s inflation target.
One form of helicopter money being discussed is the issuance of a zero coupon perpetual bond (with no maturity) by the Ministry of Finance to the Bank of Japan. The Bank of Japan “prints money” via an electronic credit of cash on its balance sheet, and uses the cash to buy the bonds. Because the bonds will pay no coupon and no principal, the Ministry of Finance would never have to pay it back.
It is important to point out the distinction between this “helicopter money” approach and QE. In QE, the central bank prints money and uses the money to buy bonds. However, the bonds eventually have to be repaid, so it adds to the overall debt levels of the country. The distinction here is the permanent nature of a perpetual bond. With QE, assets purchased are expected to be unwound at some point in the future, i.e. future generations would still have to pay back the money spent by today’s generation. With a zero coupon perpetual bond, the debt is never repaid, making this tool “helicopter money” rather than conventional QE.
Continuing with the helicopter analogy, QE is like the helicopters spilling 1,000 yen bills from the sky, but Japanese consumers and investors have been reluctant to pick up these 1,000 yen bills because the bills come with a string attached, a promise to pay back 999 yen sometime in the future. (One can think of negative interest rates as paying back less than the principal borrowed.) The zero coupon perpetual bond would instead give the money to the government for free—call it a gift. With this free money, the government should be able to embark on the most ambitious public works program ever—hire people to upgrade roads, for example, or just deposit the money directly into its citizen’s bank accounts.
But once a government undertakes helicopter money, how easy is it to wean a populous hooked on free money? Can helicopter money be done incrementally? What if the Bank of Japan manages expectations by explicitly stating that this would be a “unique event which will never be repeated” as per Milton Friedman? Can taking baby steps lead to a gradual rise in inflation, wage growth a mild depreciation of the yen, and nominal GDP growth?
