Summary: | Commodity price increases associated
with the entry of China, India, and other countries into the
world economy have led to increased pressure on
common-property renewable natural resources. The problem is
particularly worrisome for economies that obtain a large
share of their income from the exploitation of natural
resources in the production of an exportable commodity. This
paper contributes to the analysis by examining the issue in
the framework of a general equilibrium dynamic model and by
solving for both the steady state and the transition
dynamics. The authors show that i) a resource-rich,
capital-poor economy is more likely to be subject to a
"natural resource curse" and complete
(irreversible) depletion of natural resources; ii) the
latter's likelihood rises with the relative commodity
price and labor inflow; iii) a labor inflow under internal
equilibrium results in a higher steady-state capital-labor
ratio and manufacturing output, and unchanged natural
resources and commodity output; iv) import and export taxes
result in larger steady-state natural resources and
commodity output and smaller capital stock and manufacturing
output, and may prevent complete depletion of natural
resources; and v) the latter may also be prevented through
capital inflows (foreign aid), labor outflow (
liberalization of the North's immigration policy),
improved regulation, technical change, and a production tax. |
