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...

We introduce heterogeneity in agents’ risk aversion into a general equilibrium asset pricing framework with recursive preferences. Agents trade in a stock, whose dividend is the only source of consumption, and in a short-term bond in zero net supply. In equilibrium the less risk averse agents...

This study finds that a model with internal habit memory allowsto simultaneously explain a series of business cycle and asset pricing puzzles. Compared to the literature, the equity premium puzzle can be resolved in a model with endogenous labor, without giving rise to excessive risk free rate...

We examine merger activity and its effect on asset pricing in a firm network economy. Mergers create internal capital markets which change the cash flow risk structure of the merging firms. We propose a solution concept for coalitional games without the superadditivity axiom, which extends...

Control problems with Recursive Multiple-Priors Utility (RMPU) are highly non-linear so that RMPU asset prices have been studied in very simple exchange economies only. We identify a continuous-time exchange equilibrium with Locally-Constrained-Entropy RMPU (LCE-RMPU) that is tractable even in...
