In … benefits are largely associated with cyclical changes in average benefit rates. In contrast, trends in the redistributive … effects of direct and indirect taxes are mostly associated with changes in progressivity. For in-kind benefits, changes in the …

This paper studies the design of tax systems that implement a planner's second-best allocation in a market economy. An … example shows that the widely used Mirrleesian (1976) tax system cannot implement all incentive-compatible allocations … one tax system.

We characterize the second-best allocation in a Mirrleesian optimal tax model where agents differ in multiple … dimensions and the planner can tax multiple goods non-linearly. We develop a new method that allows us to solve the partial … properties of the optimum. First, the optimal tax system is described by a multidimensional version of Diamond's (1998) and Saez …
