One of the important determinants of the response of saving and consumption to the real interest rate is the elasticity of intertemporal substitution. That elasticity can be measured by the response of the rate of change of consumption to changes in the expected real interest rate. A detailed...

In a market-clearing economy, declines in demand from one sector do not cause large declines in aggregatge output because other sectors expand. The key price mediating the response is the interest rate. A decline in the rate stimulates all categories of spending. But in a low-inflation economy,...

During World War II and the Korean War, real GDP grew by about half the amount of the increase in government purchases. With allowance for other factors holding back GDP growth during those wars, the multiplier linking government purchases to GDP may be in the range of 0.7 to 1.0, a range...

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...

Macroeconomists----especially those studying monetary policy----often view the business cycle as a transitory departure from the smooth evolution of a neoclassical growth model. Important ideas contributed by Friedman, Lucas, and the developers of the sticky-price macro model generate this type...

Unemployment arises from frictions in the matching of job-seekers and employers. The level of resources that employers devote to evaluating applicants for jobs is a key factor in the magnitude of the frictions. Unemployment will be low if employers can review applicants cheaply. The cost of...

General-equilibrium models for studying monetary influences in general and the zero lower bound on the nominal interest rate in particular contain implicit theories of unemployment. In some cases, the theory is explicit. When the nominal rate is above the level that clears the current market for...

We study the paths over time that individuals follow in the labor market, as revealed in the monthly Current Population Survey. Some people face much higher flow values from work than in a non-market activity; if they lose a job, they find another soon. Others have close to equal flow values and...

Potential workers are classified as unemployed if they desire to work but are not working. The unemployed population contains two groups-those with jobs and those without jobs. Those with jobs are on furlough or temporary layoff. They wait out periods of non-work with the understanding that...

We use a rich new body of data on the experiences of unemployed jobseekers to determine the sources of wage dispersion and to create a search model consistent with the acceptance decisions the jobseekers made. Heterogeneity in non-wage job values or amenities among jobseekers and jobs is a...
