We consider an environment in which agents' skills are private information and follow arbitrary stochastic processes. We prove that it is typically Pareto optimal for an individual's marginal benefit of investing in capital to exceed his marginal cost of doing so. This wedge is consistent with a...

We study the structure of non-linear taxes in a dynamic economy subject to political economy problems. In contrast to existing literature, taxes are set by a self-interested politician, without any commitment power, who is partly controlled by the citizens. We prove that: (1) a version of the...

This paper studies a Diamond-Dybvig model of providing insurance against unobservable liquidity shocks in the presence of unobservable trades. We show that competitive equilibria are inefficient. A social planner finds it beneficial to introduce a wedge between the interest rate implicit in...

This paper provides a new, empirically driven application of the dynamic Mirrleesian framework by studying a feasible and potentially powerful tax reform: age-dependent labour income taxation. I show analytically how age dependence improves policy on both the intratemporal and intertemporal...
