Rather than trying to spur private-sector spending through asset purchases or interest-rate changes, central banks, such as the Fed, should hand consumers cash directly. In practice, this policy could take the form of giving central banks the ability to hand their countries’ tax-paying households a certain amount of money. The government could distribute cash equally to all households or, even better, aim for the bottom 80 percent of households in terms of income. Targeting those who earn the least would have two primary benefits. For one thing, lower-income households are more prone to consume, so they would provide a greater boost to spending. For another, the policy would offset rising income inequality.
Such an approach would represent the first significant innovation in monetary policy since the inception of central banking, yet it would not be a radical departure from the status quo. Most citizens already trust their central banks to manipulate interest rates. And rate changes are just as redistributive as cash transfers. When interest rates go down, for example, those borrowing at adjustable rates end up benefiting, whereas those who save — and thus depend more on interest income — lose out.
Most economists agree that cash transfers from a central bank would stimulate demand. But policymakers nonetheless continue to resist the notion. In a 2012 speech, Mervyn King, then governor of the Bank of England, argued that transfers technically counted as fiscal policy, which falls outside the purview of central bankers, a view that his Japanese counterpart, Haruhiko Kuroda, echoed this past March. Such arguments, however, are merely semantic. Distinctions between monetary and fiscal policies are a function of what governments ask their central banks to do. In other words, cash transfers would become a tool of monetary policy as soon as the banks began using them.
Other critics warn that such helicopter drops could cause inflation. The transfers, however, would be a flexible tool. Central bankers could ramp them up whenever they saw fit and raise interest rates to offset any inflationary effects, although they probably wouldn’t have to do the latter: in recent years, low inflation rates have proved remarkably resilient, even following round after round of quantitative easing. Three trends explain why.
