Reserve requirements imposed against bank deposits, nominal interest payments on bank reserves (or on base money), and inflation can all be viewed as generating tax effects. Any analysis of optimal monetary policy in a steady-state equilibrium needs to consider the simultaneous choice of all the...

In this paper we rethink the NAIRU concept and examine whether it might have a useful role in monetary policy. We argue that it can, but success depends critically on defining NAIRU as a short-run concept and distinguishing it from a long-run concept like the natural rate of unemployment. We...

We show that deviations from long-run stability of product prices are optimal in the presence of endogenous producer entry and product variety in a sticky-price model with monopolistic competition in which price stability would be optimal in the absence of entry. Specifically, a long-run...

This paper studies the role of endogenous producer entry and product creation for monetary policy analysis and business cycle dynamics in a general equilibrium model with imperfect price adjustment. Optimal monetary policy stabilizes product prices, but lets the consumer price index vary to...

The wave of crises that began in 2008 reheated the debate on market deregulation as a tool to improve economic performance. This paper addresses the consequences of increased flexibility in goods and labor markets for the conduct of monetary policy in a monetary union. We model a two-country...

We examine the potential policy role of monetary aggregates by attempting to use them as effectively as possible in the analysis of empirical relationships. We consider three possible roles: as information variables, as indicators of policy actions and as instruments in a policy rule. These...

This paper reviews the progress that the science of monetary policy has made over recent decades. This progress has significantly expanded the degree to which the practice of monetary policy reflects the application of a core set of quot;scientific principlesquot;. However, there remains, and...

This paper discusses what recent economic research tells us about exchange rate pass-through and what this suggests for the control of monetary policy. It first focuses on exchange rate pass-through from a macroeconomic perspective and then examines the microeconomic evidence. In light of this...

This paper explores the effects of labor and product market reforms in a New Keynesian, small open economy model with labor market frictions and endogenous producer entry. We show that it takes time for reforms to pay off, typically at least a couple of years. This is partly because the benefits...
