For central banks, conducting policy in an environment of uncertainty is a daily fact of life. This uncertainty can take many forms, ranging from incomplete knowledge of the correct economic model and data to future economic and geopolitical events whose precise magnitudes and effects cannot be...

The 1970s and early 1980s witnessed two main approaches to the analysis of monetary policy. The first is the early new classical approach of Lucas, based on the assumptions of rational expectations and market clearing. The second is the atheoretical econometrics of Sims' VAR program. Both have...

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...

This paper updates the standard workhorse model of banks' reserve management to include frictions inherent to money markets. We apply the model to study monetary policy implementation through an operating regime involving voluntary reserve targets (VRT). When reserves are abundant, as is the...

According to most academics and policymakers, transparency in monetary policymaking is desirable. I examine this proposition in a small theoretical model emphasizing forwardlooking private sector behavior. Transparency makes it easier for price setters to infer the central bank's future policy...

Bank leverage constraints can emerge from regulatory capital requirements as well as from central bank collateral requirements in reserve lending facilities. While these two channels are usually examined separately, we are able to compare them with the help of a bank money creation model in...

We study the macroeconomic effects of central bank digital currency (CBDC) in a dynamic general equilibrium model. Timing and information frictions create a need for inside (bank deposits) and outside money (CBDC) to finance production. To steer the quantity of CBDC, the central bank can set the...

To study implications of an interest-bearing CBDC on the economy, we integrate a New Monetarist-type decentralised market that explicitly accounts for the means-of-exchange function of bank deposits and CBDC into a New Keynesian model with financial frictions. The central bank influences the...
