The paper evaluates the performance of three popular monetary policy rules when the central bank is learning about the parameter values of a simple New Keynesian model. The three policies are: (1) the optimal non-inertial rule; (2) the optimal history-dependent rule; (3) the optimal price-level...

This paper provides a brief survey of the role of financial frictions in the monetary transmission mechanism. After noting some of the key stylised facts that any model of the transmission mechanisms must be consistent with, we discuss both the classical interest rate channel and the credit and...

The volatile data for inflation, output, and interest rates in the United Kingdom prior to the 1990s, and the relative macroeconomic stability associated with inflation targeting, provide a rich basis for discriminating between rival explanations for the outbreak of stagflation. Alternative...

This paper undertakes a Bayesian analysis of optimal monetary policy for the United Kingdom. We estimate a suite of monetary policy models that include both forward and backward-looking representations as well as large and small-scale models. We find an optimal simple Taylor-type rule that...

This paper asks two main questions: (1) What makes some asset price bubbles more costly for the real economy than others? and (2) When do costly bubbles occur? We construct a model of rational bubbles under credit frictions and show that when bubbles held by banks burst this is followed by a...

In this paper, we build a framework which can generate endogenous fluctuations in downpayment requirements. We extend the model of Kiyotaki and Moore (1997) by considering an environment, in which savers can keep their anonymity but borrowers cannot. This allows lenders to punish defaulting...

I examine whether a benevolent government can improve on the free market allocation by setting capital requirements for private borrowers in a stochastic model with collateral constraints. Previous theoretical studies have found that when asset prices enter into bor- rowing constraints,...
