This paper starts from the observation that despite their very high levels of unemployment, major European countries … have devoted few resources to reducing it. This suggests that there is little political concern about high unemployment. I …

Under weak conditions, low-unemployment equilibria Pareto … dominate high-unemployment equilibria. Mobility premia improve aggregate welfare but may increase unemployment. …

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 unemployment, especially during recessions: the fiscal multiplier …
