An examination of data on labor input and the quantity of output reveals that most U.S. industries have marginal costs far below their prices. The corilusion rests on the empirical finding that cyclical variations in labor input are small compared to variations in output. In booms, firms produce...

Though the U.S. labor market is justly notorious for high turnover and consequent high unemployment, it also provides stable, near-lifetime employment to an important fraction of the labor force. This paper investigates patterns of job duration by age, race, and sex, with the following major...

Market power arises in the case where a seller is aware that raising output will depress price. In the profit-maximizing equilibrium with market power, price exceeds marginal cost. The Lerner index---the ratio of price less marginal cost to the price---is a widely accepted measure of market...

New data compel a new view of events in the labor market during a recession. Unemployment rises almost entirely because jobs become harder to find. Recessions involve little increase in the flow of workers out of jobs. Another important finding from new data is that a large fraction of workers...

This paper sets forth a simple general structural model of aggregate output, the interest rate, and the price level. The core of the model is the determination of the level of output as a product-market equilibrium, either competitive or oligopolistic, possible indeterminate because of...

The markup of price over marginal cost reveals market power. The distinction between marginal and average cost is key. Average cost is easy to measure, but the price/average cost ratio understates the price/marginal cost ratio when fixed costs are present. In particular, in free-entry...

The financial crisis and ensuing Great Recession left the U.S. economy in an injured state. In 2013, output was 13 percent below its trend path from 1990 through 2007. Part of this shortfall--2.2 percentage points out of the 13--was the result of lingering slackness in the labor market in the...

It is a remarkable fact about the historical US business cycle that, after unemployment reached its peak in a recession, and a recovery began, the annual reduction in the unemployment rate was stable at around 0.55 percentage points per year. The economy seems to have had an irresistible force...

This paper discusses nominal income targeting as a possible rule for the conduct of monetary policy. We begin by discussing why a rule for monetary policy may be desirable and the characteristics that a good rule should have. We emphasize, in particular, three types of nominal income targets,...
