| Tiivistelmä: | We investigate optimal policies for the exploitation of a renewable resource subject to a concave growth function and a convex return function. We prove an important result on the elasticity of the objective function and apply it to give a characterization of the optimal harvesting paths in this class of models. In particular, we derive conditions such that all optimal programs converge to a fixed point or to a cycle of finite period, and hence result in the conservation of the resource. We also show which assumptions guarantee that extinctions of the stock is optimal. That nonconvex preferences or technologies cause problems for economic theory is well-known. |
