Employment and hours appear far more cyclical than dictated by the behavior of productivity and consumption. This puzzle has been labeled "the labor wedge" -- a cyclical wedge between the marginal product of labor and the marginal rate of substitution of consumption for leisure. The wedge can be...

This study constructs a new data set on unemployment rates in Latin America and the Caribbean and then explores the determinants of unemployment. We compare different countries, finding that unemployment is influenced by the size of the rural population and that the effects of government...

We introduce worker differences in labor supply, reflecting differences in skills and assets, into a model of separations, matching, and unemployment over the business cycle. Separating from employment when unemployment duration is long is particularly costly for workers with high labor supply....

This paper discusses the NAIRU -- the non-accelerating inflation rate of unemployment. It first considers the role of the NAIRU concept in business cycle theory, arguing that this concept is implicit in any model in which monetary policy influences both inflation and unemployment. The exact...

This paper argues that hysteresis helps explain the long-run behavior of unemployment. The natural rate of unemployment is influenced by the path of actual unemployment, and hence by shifts in aggregate demand. I review past evidence for hysteresis effects and present new evidence for 20...

This paper asks how well Okun's Law fits short-run unemployment movements in the United States since 1948 and in twenty advanced economies since 1980. We find that Okun's Law is a strong and stable relationship in most countries, one that did not change substantially during the Great Recession....

We consider a matching model of employment with wages that are flexible for new hires, but sticky within matches. We depart from standard treatments of sticky wages by allowing effort to respond to the wage being too high or low. Shimer (2004) and others have illustrated that employment in the...

We model unemployment allowing workers to differ by comparative advantage in market work. Workers with comparative advantage are identified by who works more hours when employed. This enables us to test the model by grouping workers based on their long-term wages and hours from panel data. The...
