A possible arrangement, set up in advance, might work as follows: Ask Congress to create, by statute, a special Treasury account at the Fed, and to give the Fed . . . the sole authority to “fill” the account, perhaps up to some prespecified limit. At almost all times, the account would be empty; the Fed would use its authority to add funds to the account only when the [Fed] assessed that a [helicopter drop] of specified size was needed to achieve the Fed’s employment and inflation goals.
Should the Fed act, under this proposal, the next step would be for the Congress and the Administration—through the usual, but possibly expedited, legislative process—to determine how to spend the funds (for example, on a tax rebate or on public works). Importantly, the Congress and Administration would have the option to leave the funds unspent. If the funds were not used within a specified time, the Fed would be empowered to withdraw them.
