Each of the main explanations of procyclical labor productivity, or short-run increasing returns to labor (SRIRL), is closely associated with a competing theory of the business cycle: Real business cycle theorists attribute SRIRL to procyclical technological shocks, proponents of recent theories...

Employment and hours appear far more cyclical than dictated by the behavior of productivity and consumption. This puzzle has been called “the labor wedge” — a cyclical intratemporal wedge between the marginal product of labor and the marginal rate of substitution of consumption for...

We examine monthly variation in weekly work hours using data for 2003-10 from the Current Population Survey (CPS) on hours/worker, from the Current Employment Survey (CES) on hours/job, and from the American Time Use Survey (ATUS) on both. The ATUS data minimize recall difficulties and constrain...

A longstanding puzzle of empirical economics is that average labor productivity declines during recessions and increases during booms. This paper provides a framework to assess the empirical importance of competing hypotheses for explaining the observed procyclicality. For each competing...

This paper argues that a broad class of search models cannot generate the observed business-cycle-frequency fluctuations in unemployment and job vacancies in response to shocks of a plausible magnitude. In the U.S., the vacancy-unemployment ratio is 20 times as volatile as average labor...

Many economists suspect that downward nominal wage rigidities in ongoing labor contracts are an important source of employment fluctuations over the business cycle but there is little direct empirical evidence on this conjecture. This paper compares three occupations in the housing sector with...

This paper explores role of product adding and dropping within manufacturing firms over the business cycle. While a substantial body of work has explored the importance of the extensive margins of firm entry and exit in employment and output flows, only recently has research begun to examine the...

Manufacturers' finished goods inventories move less than shipments over the business cycle. We argue that this requires marginal cost to be more procyclical than is conventionally measured. We construct, for six manufacturing industries, alternative measures of marginal cost that attribute...

One goal of extending the duration of unemployment insurance (UI) in recessions is to increase UI coverage in the face of longer unemployment spells. Although it is a common concern that such extensions may themselves raise nonemployment durations, it is not known how recessions would affect the...

A labor market tautology says that any change in labor usage can be decomposed into a movement along a marginal productivity schedule and a shift of the schedule. I calculate this decomposition for the recession of 2008, assuming an aggregate Cobb-Douglas marginal productivity schedule, and find...
