Although policymakers and commentators have repeatedly stressed the impact of uncertainty about the true state of the economy on the setting of interest rates, the academic literature has largely ignored this issue. This paper provides a theoretical analysis of how uncertainty about the true...

We present empirical evidence that the marked rise in liquidity in 2001-2007 was due to large and persistent current account deficits and loose monetary policy. If this increase in liquidity was a pre-condition for the financial crisis that began in July 2007, we can conclude that loose monetary...

We argue that although UK monetary policy can be described using a Taylor rule in 1992-2007, this rule fails during the recent financial crisis. We interpret this as reflecting a change in policymakers’ preferences to give priority to stabilising the financial system. Developing a model of...

The opportunistic approach to monetary policy is an influential but untested model of optimal monetary policy. We provide the first tests of the model, using US data from 1983Q1 to 2004Q1. Our results support the opportunistic approach. We find that policy-makers respond to the gap between...

This paper analyses the impact of uncertainty about the true state of the economy on monetary policy rules in the US since the early 1980s. Extending the Taylor rule to allow for this type of uncertainty, we find evidence that the predictions of the theoretical literature on responses to...

The “sub-prime” crisis, which led to major turbulence in global financial markets beginning in mid-2007, has posed major challenges for monetary policymakers. We analyse the impact on monetary policy of the widening differential between policy rates and the 3-month Libor rate, the benchmark...
