We consider a dynamic Mirrlees economy in a life cycle context and study the optimal insurance arrangement. Individual productivity evolves as a Markov process and is private information. We use a first order approach in discrete and continuous time and obtain novel theoretical and numerical...

A Positive Theory of Capital Taxation

efficiency gains can be sizable, but we find that most of the improvements can then attributed to the relaxation of borrowing constraints, rather than the introduction of savings distortions.

"We consider a dynamic Mirrlees economy in a life cycle context and study the op- timal insurance arrangement. Individual productivity evolves as a Markov process and is private information. We use a first order approach in discrete and continuous time and obtain novel theoretical and numerical...

"This paper derives an intertemporal optimality condition for economies with private information, focusing on a class of recursive preferences. By comparing it to the situation where agents can freely save in a risk-free asset market, we derive the optimal savings distortions necessary for...
