How long do excess savings from deficit-financed transfers affect demand?
Core argument: Excess savings from deficit-financed fiscal transfers are expected to influence the economy for up to five years as they "trickle up" the wealth distribution toward households with lower marginal propensities to consume, prolonging the effect on aggregate demand.
Excess savings from deficit-financed fiscal transfers are expected to influence the economy for up to five years, as they gradually move up the wealth distribution to individuals with lower marginal propensities to consume (MPCs). This process, known as "trickling up," implies that the impact of these savings on aggregate demand is more prolonged than previously assumed. In a closed economy, unless the government reduces the debt used for these transfers, excess savings persist even as households spend them. Tight monetary policy can modestly accelerate this process by mitigating the effects on demand, but the duration of excess savings and their impact on output remains significantly longer than conventional wisdom suggests. The effect is particularly pronounced when MPCs are lower, highlighting the importance of understanding savings distribution in macroeconomic forecasting.
