How much of aggregate employment fluctuations is due to plants destroying and then recreating the same jobs over the cycle and how much is due to some plants permanently destroying jobs in a recession and other plants permanently creating jobs in an expansion? This paper decomposes plant level...

I use the term workweek flexibility to describe the ease of changing output by altering the number of hours per worker. Despite the fact that workweek flexibility is potentially important for understanding the cyclical behavior of marginal cost and prices, as well as cyclical movements in hours...

Using a band pass filter, this paper estimates plant-level job flows at different frequencies and examines the characteristics of the high frequency (transitory) and low frequency (permanent) component flows. Because high frequency employment movements, which likely result in changes in the...

The movement of hours worked over the business cycle is an important input into the estimation of many key parameters in macroeconomics. Unfortunately, the available data on hours do not correspond precisely to the concept required for accurate inference. We study one source of...

An important step in understanding why employment fluctuates cyclically is determining the relative importance of cyclical movements in permanent and temporary plant-level employment changes. If movements in permanent employment changes are important, then recessions are times when the...

A number of industries underwent large and permanent reductions in employment growth at the beginning of this decade, a process we label as restructuring. We describe how restructuring occurred and what its consequences were for the economy. In particular, we find that restructuring stemmed...

This paper finds that the permanent job losses associated with industrial restructuring have significantly boosted the variance of unemployment, causing it to rise much higher in recessions than it would have without cyclically correlated restructuring. Moreover, the influence of restructuring...

I examine whether the cyclical behavior of unemployment has changed over the post WWII period. Specifically, I test whether cyclical movements in unemployment have become more persistent. Finding that they have, indeed, become more persistent, I then take some initial steps in explaining why. I...

This paper presents a framework to study movements in the matching efficiency of the labor market and highlights two observable factors affecting matching efficiency: (i) unemployment composition and (ii) dispersion in labor market conditions, the fact that tight labor markets coexist with slack...

This paper presents a framework to interpret movements in the Beveridge curve and analyze unemployment fluctuations. We decompose the unemployment rate into three main components: (1) a component driven by changes in labor demand--movements along the Beveridge curve and shifts in the Beveridge...
