We solve a large class of multidimensional adverse selection problems with one observed action, to derive the nonlinear optimal income tax schedule when individuals differ along multiple unobserved characteristics. Based on a perturbation of the optimal allocation, our method allows individuals...

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

The Dutch Parliament has passed legislation for a new income tax that abolishes the current tax on personal capital income and substitutes it by a presumptive capital income tax, which is in fact a net wealth tax. This paper contrasts this wealth tax with a conventional realization-based capital...

We derive a sufficient statistics optimal tax formula in a general model that incorporates unemployment and endogenous wages, to study the shape of the tax and transfer system at the bottom of the distribution. The sufficient statistics are the macro employment response to taxation and the micro...
