We wish to study optimal dynamic nonlinear income taxes. Do real-world taxes share some of their features? What policy prescriptions can be made? We study a two-period model, where the consumers and government each have separate budget constraints in the two periods, so income cannot be...

Conventional wisdom tells us that with no market failure and local non- satiation of preferences, the core is at least as large as the collection of competitive equilibrium allocations. We confirm this for a standard model featuring land. Next we consider the public land ownership version of the...

We make two contributions to the theory of optimal income taxation. First, assuming conditions sufficient for existence of a Pareto optimal income tax and public goods mechanism, we show that if agents' preferences satisfy an extended notion of single crossing called capacity constrained single...
