Whenever unemployment stays high for an extended period, it is common to see analyses, statements, and rebuttals about the extent to which the high unemployment is structural, not cyclical. This essay views the Beveridge Curve pattern of unemployment and vacancy rates and the related matching...

In this paper, I investigate US post war price, wage and employment dynamics by identifying and estimating a price and a wage equation. I reach the following two main conclusions: Nominal wages adjust faster to prices than prices do to nominal wages. This may be taken as evidence that price...

This paper rehabilitates the old wage price spiral. It shows that, after an increase in aggregate demand, the process of adjustment of nominal prices and nominal wages results from attempts by workers to maintain or increase their real wage and by firms to maintain or increase their markups of...

Many issues in macroeconomics, such as the level of the steady state interest rate, or the dynamic effects of government deficit finance, depend crucially on the horizon of economic agents. This paper develops a simple analytical model in which such issues can be examined and in which the...

This paper examines, in light of the Lucas Critique, the behavior of the Phillips curve and of the term structure of interest rates after October 1979. It starts with an informal account of the policy change and then discusses how we might expect these two relations to shift after such a change....

There is widespread feeling that current deficits, in Europe and the U.S.,may hurt rather than help the recovery. This paper examines some of the issues involved, through a sequence of three models.The first model focuses on sustainability and characterizes its determinants. It suggests that the...

A decrease in aggregate demand at given prices and wages decreases output and employment. The decrease in employment exerts downward pressure on real wages. The decrease in production exerts downward pressure on markups. With perfectly synchronized price and wage decisions, nominal wages and...

If price decisions are taken neither continuously nor in perfect synchronization, the process of adjustment of all prices to a new nominal level will imply temporary movements in relative prices. It might then well be that, to avoid these movements in relative prices, each price setter will want...

Understanding inventory movements is central to an understanding of business cycles. This paper presents an empirical study of the behavior of inventories in the automobile industry. It finds that inventory behavior is well explained by the assumption of intertemporal optimization with rational...

First, I show that the current U.S. situation in which safe interest rates are expected to remain below growth rates for a long time, is more the historical norm than the exception. If the future is like the past, this implies that debt rollovers, that is the issuance of debt without a later...
