This paper examines how allowing individuals to emigrate to pay lower taxes changes the optimal non-linear income tax scheme in a Mirrleesian economy. Type-dependent participation constraints are borrowed from contract theory. An individual emigrates if his domestic utility is less than his...

This article discusses the properties of Kolm’s ELIE proposal in the Context of optimal income taxation “à la Mirrlees”. It first shows that ELIE gives rise to non-standard type-dependent budget sets, which has important implications in terms of a minimum labour requirement. Second, it...
