Monetary Policy

Abstract

This chapter discusses monetary policy. It is informally divided in two parts: The former discusses the rationale for and the main features of the current institutional ‘architecture’ related to monetary policy. A formal analysis of time inconsistency of optimal discretionary policy and the concomitant inflationary bias is followed by analyses of commitment and reputation. Subsequently, the Chapter looks at possible resolutions of the difficulties associated with discretionary policy, including independent Central Banks and inflation targeting. It also discusses the new features and proposals that emerged post-2007–9. A ‘policy in practice’ section looks at Taylor rules. In the latter part, we review the recent analyses on financial structure and the ‘credit channel(s)’ of monetary policy transmission. The chapter concludes with a review of Quantitative Easing, macroprudential regulation, and the current thinking on monetary policy as part of a wider package of optimal stabilization policy.
