Abstract
The paper presents two new results for the Dasgupta-Heal-Solow-Stiglitz model with an essential nonrenewable resource: (1) the pattern of resource extraction can be more important for sustainable growth than the pattern of saving when the Hotelling Rule modifier is not small enough; (2) the qualitative behavior of the long-run per capita consumption can be examined along any smooth enough path of extraction using the "sustainability functional" introduced in the paper.sustainable growth; modified Hotelling Rule; sustainability number; Hubbert curve consumption
