RENEWABLE NATURAL RESOURCES AND ENDOGENOUS GROWTH

Abstract

We study the sustainability of long-run growth in a two-sector economy where a renewable natural resource is exploited under private property rights. We obtain short- and long-run growth trajectories in closed form, examine transitional dynamics, and characterize convergence properties. We find conditions for sustainable long-run growth, which depend on the harvesting rate, and show that the speed of convergence decreases during transition. We identify a stronger version of Hartwick's rule and analyze parameter dependences for endogenous variables. Economic growth relies less on abundance or scarcity of natural resources than on the way they are managed.
