IZA DP No. 446: Macroeconomic Policy Lessons of Labor Market Frictions
published in: European Economic Review, 2004, 48 (2), 259-284
The paper explores the consequences of macroeconomic policy for labor market outcomes in the presence of frictions. It shows how policy may be useful in overriding frictions, as well as how it might generate adverse outcomes. The analysis looks at the main tools of macroeconomic policy and pertains to both the non-stochastic steady state and to business cycle fluctuations. A partial-equilibrium, empirically-grounded model is used to simulate policy effects. It relies on a reduced-form VAR of the actual data to specify the stochastic behavior of exogenous variables, precluding the possibility that labor market results will be affected by misspecifications in other parts of a more general macroeconomic model. The key results are that policy has effects on the stochastic behavior of key variables - measures that reduce unemployment also reduce its persistence and increase the volatility of vacancies. Hiring subsidies and unemployment benefits have substantial effects on labor market outcomes, while employment subsidies or wage tax reductions are not very effective policy instruments.
