The paper discusses several issues related to how monetary policy should be conducted in an era of price stability. Low inflation (with base drift in the price level) and price-level stability (without such base drift) are compared, and a suitable loss function (corresponding to flexible...

We show that if the central bank operates without commitment and faces constraints on its balance sheet, helicopter drops can be a useful stabilization tool during a liquidity trap. With commitment, even with balance sheet constraints, helicopter drops are irrelevant

We empirically characterize episodes of large inflation surges that have been observed worldwide in the last three decades. We document four facts. (1) Inflation following surges tends to be persistent, with the duration of disinflation exceeding that of the initial inflation increase. (2)...

This paper analyzes the dramatic rise in U.S. inflation since 2020, which we decompose into a rise in core inflation as measured by the weighted median inflation rate and deviations of headline inflation from core. We explain the rise in core with two factors, the tightening of the labor market...

The European Central Bank is unique in setting monetary policy for several sovereign states with heterogeneous debt levels and different maturity structures. The monetary-fiscal nexus is central to the functioning of the euro area. We focus on one particular aspect of that nexus, the effect the...

Existing proposals to escape from a liquidity trap and deflation, including my Foolproof Way,' are discussed in the light of the optimal way to escape. The optimal way involves three elements: (1) an explicit central-bank commitment to a higher future price level; (2) a concrete action that...

This paper considers whether 'liquidity trap' issues have important bearing on the desirability of inflation targeting as a strategy for monetary policy. From a theoretical perspective, it has been suggested that 'expectation trap' and 'indeterminacy' dangers are created by variants of inflation...

We design a new experimental framework to study policy interventions to combat secular stagnations and liquidity traps in an overlapping-generations environment where participants form expectations and make real economic decisions. We observe that participants can learn to coordinate on high...

This paper discusses how price stability can be defined and how price stability can be maintained in practice. Some lessons for the Eurosystem are also considered. With regard to defining price stability, the choice between price-level stability and low (including zero) inflation and the...

We study whether a central bank should deviate from its objective of price stability to promote financial stability. We tackle this question within a textbook New Keynesian model augmented with capital accumulation and microfounded endogenous financial crises. We compare several interest rate...
