This paper asks whether tax cycles can represent the optimal policy in a model without any extrinsic uncertainty. I show, in an economy without capital and where labor is the only choicevariable (a Lucas-Stokey economy), that a large class of preferences exists, where cycles are optimal, as well...

We study the optimal path for capital and labor taxes in a dynamic economy with heterogeneous agents. In an otherwise standard model we concentrate on tax reforms that are both Pareto effcient and Pareto improving. Also, we assume the capital tax rate can never rise above its initial level and...

In discrete time, every time-consistent dynamic monetary risk measure can be written as a composition of one-step risk measures. We exploit this structure to give new dual representation results for time-consistent convex monetary risk measures in terms of one-step penalty functions. We first...

We consider a class of law-invariant convex risk measures which have a.robust representation of the form ρ(X ) = ...... . The supremum is taken over the set of all Radon Nikodym derivatives corresponding to the set of all probability measures on B(0,1] which are absolutely continuous with...
