This paper discusses how optimal monetary policy is affected by differences in the combination of shocks an economy experiences and the rigidities it exhibits. Without both nominal rigidities and economic shocks, monetary policy would be irrelevant. Recognizing this, policymakers increasingly...

The design of rules for central bank policy has been a subject of increasing interest to many monetary economists. The purpose of this essay is first to present an analytical structure in which a policymaker is presumed to formulate a rule based on the solution to an optimal control problem, and...

As central bankers intensify their focus on inflation as the primary goal of monetary policy, it becomes increasingly important to have accurate and reliable measures of changes in the aggregate price level. Measuring inflation is surprisingly difficult, involving two types of problems. Commonly...

In recent years, central bankers throughout the world have advocated that monetary policy shift toward inflation targeting. Recent actions in the U.S. serve to highlight the desire of the Federal Reserve to keep inflation both low and stable, while downplaying the likely output and employment...

This paper investigates the effects of wage indexation on the time-consistent level of inflation. Departing from previous work on time-consistent policy, we study a structural model of the economy. Indexation reduces the cost of inflation, which is inflationary, and steepens the Phillips curve,...

A simple New-Keynesian model is set out with AS-AD graphical analysis. The model is consistent with modern central banking, which targets shortterm nominal interest rates instead of money supply aggregates. This simple framework enables us to analyze the economic impact of productivity or markup...

Standard discussions of flexible inflation targeting as an optimal monetary policy abstract completely from the consequences of monetary policy for the government budget. But at least some of the countries now adopting inflation targeting have substantial difficulty in controlling fiscal...

some stylized facts relating the regional dispersion in headline inflation rates in the euro area as well as in the main components of the consumer price index. We find that a relatively large proportion of it occurs in the Service category of the EU's harmonized consumer price index (HICP). We...

Erceg et al. (2000) show that when both wages and prices are sticky, maximization of expected utility is equivalent to minimizing a loss function with three terms, involving measures of the variability of wage inflation, price inflation and the output gap respectively. Here we generalize their...
