We augment a standard New Keynesian model with a financial accelerator mechanism and show that financial frictions generate large state-dependent amplification effects. We fit the model to US data and show that, when shocks drive the model far away from the steady state, the nonlinear model...

In this paper, we examine the link between political transparency of a common central bank (CCB) and decentralized supply-side fiscal policies in a monetary union. We find that the opacity of a conservative CCB has a restrictive effect on national fiscal policies since each government...

We show that firms which face higher uncertainty adjust their investment less in response to monetary policy shocks. We find corroborating evidence of this differential effect from firm-level stock returns on FOMC announcement days. Our results are explained by a real options or...

The enlargement of the European Monetary Union is likely to lead to an increase in uncertainty regarding the transmission of monetary policy for the larger union. Adding new members to the central bank council will in addition imply that the policy reaction of the enlarged council will be...

The article reviews the literature on the relationship between climate change and central bank policies. Central banks conduct monetary policy and are responsible for macroprudential supervision. The article focuses on the consequences of transition and physical risks for financial stability and...

This paper explores the effects of central bank transparency on the performance of optimal inflation targeting rules. I assume that both the central bank and the private sector face uncertainty about the correct model of the economy and have to learn. A transparent central bank can reduce one...

The implications of uncertain policy preferences for the targeting and contracting approaches to monetary policy are investigated. It is shown that, in the presence of uncertain preferences, a linear incentive contract in the sense of Walsh performs better than an explicit inflation target as...

After the Lehman default, but also during the euro area sovereign debt crisis, central banks have tended to extend the ability of banks to take recourse to central bank credit operations through changes of the collateral framework (e.g. CGFS, 2008 – in consistence with previous narratives,...

When communicating with the public about the state of the economy, central bankers not only need to decide the messages they want to convey, but also how much to focus on various relevant economic variables. I consider a policymaker whose objective is to minimise the mean-squared error of...

Uncertainty is a ubiquitous concern emphasized by policymakers. We study how uncertainty affects decision-making by the Federal Open Market Committee (FOMC). We distinguish between the notion of Fed-managed uncertainty vis-a-vis uncertainty that emanates from within the economy and which the Fed...
