The structural rate of unemployment and associated non-accelerating inflation rate of unemployment (the NAIRU) are of major importance to the analysis of macro and structural economic developments, although in practice these concepts are not well defined and there is considerable uncertainty and...

This paper uses a variety of empirical methods to examine the apparent differences in monetary policy stances as between the United States and other G7 economies, notably those in the euro area, during the period of sharp increases in oil and other commodity prices in the first half of 2008. In...

This paper assesses the OECD’s projections for GDP growth and inflation during the global financial crisis and recovery, focussing on lessons that can be learned. The projections repeatedly over-estimated growth, failing to anticipate the extent of the slowdown and later the weak pace of the...

Many observers suggest that the "globalization" of the U.S. economy has changed the behavior of inflation. This essay examines this idea, focusing on several questions: (1) Has globalization reduced the long-run level of inflation? (2) Has it affected the structure of inflation dynamics, as...

This paper studies the welfare effects of the relative price variability arising from inflation. When agents interact in anonymous markets, with customers buying from new suppliers each period, relative price variability benefits customers and cannot harm suppliers substantially. But if...

We present a model in which workers' aspirations for wage increases adjust slowly to shifts in productivity growth. The model yields a Phillips curve with a new variable: the gap between productivity growth and an average of past wage growth. Empirically, this variable shows up strongly in the...

This paper investigates the determinants of the "sacrifice ratio" for disinflation: the ratio of the loss in output to the fall in trend inflation. I develop a method for estimating the sacrifice ratio in individual disinflation episodes, and apply it to 65 episodes in moderate-inflation OECD...

This paper discusses the NAIRU -- the non-accelerating inflation rate of unemployment. It first considers the role of the NAIRU concept in business cycle theory, arguing that this concept is implicit in any model in which monetary policy influences both inflation and unemployment. The exact...

This paper asks why the NAIRU rose in most OECD countries in the 1980s. I find that a central cause was the tight monetary policy used to reduce inflation. The evidence comes from a cross-country comparison: countries with larger decreases in inflation and longer disinflationary periods have...

This paper presents a model of a high-inflation economy. The model includes the government budget constraint and money demand equation of Cagan's 1956 model; an accelerationist Phillips curve that captures inflation inertia; and an aggregate-spending equation that accounts for the effects of the...
