A model of optimal discounting in presence of non renewable resource extraction is presented here. By means of a two-step optimal control problem, we derive the determinants of the social discount rate that a hypothetical social planner should set to drive the economy towards a path where...

A model of optimal harvesting natural resources is presented to show the appropriate management decision rule a natural-based society should follow to prevent its environment from over-exploitation. This optimal control analysis is likely to produce some changes in the topological structure of...
