This paper proposes a tractable way to model boundedly rational dynamic programming. The agent uses an endogenously simplified or "sparse" model of the world and the consequences of his actions, and act according to a behavioral Bellman equation. The framework is applied to some of the canonical...

This paper addresses the spatial evolution of countries accounting for economics, geography and (military) force. Economic activity is spatially distributed following the AK model with the output being split into consumption, investment, transport costs and military (for defense and expansion)....

This paper proves the C1,1 differentiability of the value function for continuous time concave dynamic optimization problems, under the assumption that the instantaneous utility is C1,1 and the initial segment of optimal solutions is interior. From this result, the Lipschitz dependence of...
