In an economy where agents have different productivities and mobility, we compare a unified nonlinear optimal taxation with the equilibrium taxation that would be chosen by two competing tax authorities if the same economy were divided into two States. The overall level of progressivity and redistribution is unambiguously lower under competitive taxation;(More)

We provide approximation results for Nash equilibria in possibly discon-tinuous games when payoffs and strategy sets are perturbed. We then prove existence results for a new " finitistic " infinite-game generalization of Selten's (Int J Game Theory 4: 25–55, 1975) notion of perfection and study some of its properties. The existence results, which rely on(More)
