Labor tax reform and equilibrium unemployment:a search and matching approach

The paper studies simple strategies of labor tax reform in a search and matching model of the labor market featuring endogenous labor supply. Changing the composition of the tax wedge---that is, reducing a payroll tax and increasing a progressive wage tax such that the marginal tax wedge remains unaffected---increases employment, reduces the equilibrium unemployment rate, and increases public revenue as long as workers do not have all the bargaining power in wage negotiations. A strategy of replacing employment taxes by payroll taxes increases employment and reduces the equilibrium unemployment rate, while the effect on public revenue is ambiguous
