Abstract

Evidence suggests that monetary policy can affect long-term real interest rates, but it is not clear what drives this outcome. We argue this occurs because very persistent policy-induced interest rate changes may have only weak effects on activity. This can arise when consumption-savings decisions are not primarily driven by intertemporal substitution, but also by life-cycle forces associated with retirement. Within such an environment, we show that the impact of highly persistent monetary policy shocks on activity is determined by two forces: an asset valuation effect, and the response of the average marginal propensity to consume out of financial wealth. Our quantitative analysis indicates that these forces likely cancel each other out, allowing monetary policy to (unconsciously) drive trends in long-run real rates. Our findings also imply that very precise knowledge of r* might not be essential to the successful conduct of monetary policy.
