This paper develops a model of unemployment fluctuations. The model keeps the architecture of the Barro and Grossman (1971) general disequilibrium model but replaces the disequilibrium framework on the labor and product markets by a matching framework. On the product and labor markets, both...

I develop a New Keynesian model in which a type of government multiplier doubles when unemployment rises from 5 percent to 8 percent. This multiplier indicates the additional number of workers employed when one worker is hired in the public sector. Graphically, in equilibrium, an upward-sloping...

This paper illustrates why fiscal policy becomes more effective as unemployment rises in recessions. The theory is based on the equilibrium unemployment model of Michaillat (forthcoming), in which jobs are rationed in recessions. Fiscal policy takes the form of government spending on...

This paper models unemployment as the result of matching frictions and job rationing. Job rationing is a shortage of jobs arising naturally in an economic equilibrium from the combination of some wage rigidity and diminishing marginal returns to labor. During recessions, job rationing is acute,...

This article is based on a paper that models unemployment as the result of matching frictions and job rationing. Job rationing is a shortage of jobs arising naturally in an economic equilibrium from the combination of some wage rigidity and diminishing marginal returns to labor. During...

This paper characterizes optimal unemployment insurance (UI) over the business cycle using a model of equilibrium unemployment in which jobs are rationed in recession. It offers a simple optimal UI formula that can be applied to a broad class of equilibrium unemployment models. In addition to...

This paper develops a theory characterizing the effects of fiscal policy on unemployment over the business cycle. The theory is based on a model of equilibrium unemployment in which jobs are rationed in recessions. Fiscal policy in the form of government spending on public-sector jobs reduces...

We present a static model of aggregate demand and unemployment. The economy has a nonproduced good, a produced good, and labor. Product and labor markets have matching frictions. A general equilibrium is a set of prices, market tightnesses, and quantities such that buyers and sellers optimize...
