In this Paper, we take the field of optimal dynamic taxation further in two directions. Using a model with invisible labour, as in Hansen (1986) and Rogerson (1988), we first explore the short-run dynamics of the capital-income tax, particularly whether the tax, under the second-best programme,...

We analyze optimal dynamic taxation when labor supply is indivisible, as in Hansen (1985) and Rogerson (1988). Markets are complete, and an employment lottery determines who works.
