The ECB Strategy Review

📖 The Scoop

This paper investigates two important elements of the ECB's 2021 monetary policy strategy review in an estimated structural open-economy macro model of the euro area: (a) explicit symmetry of the 2% inflation target, which can be expected to lower the risk of hitting the effective lower bound (ELB) on short-term interest rates by raising average inflation towards the target, and (b) commitment to forceful or persistent monetary accommodation in a low interest rate environment, here interpreted as low-for-longer response in the recovery from the ELB. We simulate the model with draws from the estimated distribution of shocks. Both elements increase average inflation and reduce the average output gap. Stabilisation gains are modest in quantitative terms, however, for the given illustrative policy rules, and they are more pronounced when the economy operates at the ELB. Important in the current context, the low-for-longer policy in the model does not jeopardise inflation stabilisation in the event of (inflationary) negative supply shocks at the exit from the ELB. With private sector 'myopia' instead of fully rational expectations, the low-for-longer rule still yields stabilisation gains at the ELB, but they shrink in quantitative terms.
