Because of Time Inconsistency considerations, policymakers underestimate the drawbacks of wage rigidity as a redistributive tool. Consequently, they redistribute inefficiently income from high to low skilled workers. They typically implement too much wage rigidity whereas other means (in...

In this paper, I introduce money in the standard labor-matching model (Mortensen and Pissarides 1999, Pissarides 2000). A double coincidence problem makes Fiat Money necessary as a medium of exchange. In the long-run, a rise in the rate of money growth leads to higher inflation and higher...

We build a theoretical model to study whether a minimum wage can be welfare-improving if itis implemented in conjunction with an optimized nonlinear income tax. We consider this issuein a framework where search frictions on the labor market generate unemployment. Workersdiffer in productivity...

We analyze the optimal nonlinear income tax schedule when taxpayers earn multiple in- comes and differ along many unobserved dimensions. We derive the necessary conditions for the government's optimum using both a tax perturbation and a mechanism design approach, and show that both methods...

We theoretically express the Laffer tax rate on capital income as a function of the elasticities of capital income (the "direct" elasticity) and of labor income (the "cross" elasticity) with respect to the net-of-tax rate on capital income. We estimate these elasticities using salient capital...

This paper characterizes optimal income taxation when individuals respond along both theintensive and extensive margins. Individuals are heterogeneous across two dimensions:specifically, their skill and disutility of participation. Preferences over consumption and workeffort can differ with...

We estimate the responses of gross labor earnings with respect to marginal and average netof-tax rates in France over the period 2003-2006. We exploit a series of reforms to theincome-tax and the payroll-tax schedules that affect individuals who earn less than twice theminimum wage. Our estimate...

We investigate how the optimal nonlinear income tax schedule is modified when taxpayers can evade taxation by emigrating. We consider two symmetric countries with Maximin governments. Workers choose their labor supply along the intensive margin. The skill distribution is continuous, and, for...
