In a textbook New Keynesian model extended to allow for uninsurable household income risk, any path of inflation and output implementable via interest rate policy is similarly implementable through uniform lump-sum transfers ("stimulus checks"). A dual-mandate policymaker can thus use checks to perfectly substitute for conventional monetary policy when rates are constrained by a lower bound. In a quantitative heterogeneous-agent (HANK) model, the stimulus check policy that implements a given monetary allocation is well-characterized by a small number of measurable sufficient statistics. In the household cross-section, the transfer policy is associated with lower consumption inequality than the equivalent rate cut.
