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...

This paper analyzes optimal unemployment insurance over the business cycle in a search model in which unemployment stems from matching frictions (in booms) and job rationing (in recessions). Job rationing during recessions introduces two novel effects ignored in previous studies of optimal...

This paper analyzes optimal unemployment insurance (UI) over the business cycle. We consider a general matching model of the labor market. For a given UI, the economy is efficient if tightness satisfies a generalized Hosios condition, slack if tightness is too low, and tight if tightness is too...

We develop a theory of optimal unemployment insurance (UI) that accounts for workers’ job-search behavior and firms’ hiring behavior. The optimal replacement rate of UI is the conventional Baily [1978]-Chetty [2006a] rate, which solves the trade-off between insurance and job-search...

This paper explains the nonneutrality of money from two assumptions: (1) consumers dislike paying prices that exceed some fair markup on firms' marginal costs; and (2) consumers under infer marginal costs from available information. After an increase in money supply, consumers underappreciate...

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,...
