The relationships among the Hamiltonian, NNP, and the level of sustainable consumption/utility have been widely misunderstood. This paper dispels the misconceptions and provides further new insight into these relationships. We show generally that for autonomous dynamic optimizing economies, a...

I focus on two alternative concepts of sustainability dominating the literature: (i) maximum permanently maintainable consumption level (Fisherian income) and (ii) the amount of consumption that leaves total value of wealth intact (Hicksian income). In the context of a pure exhaustible resource...

This paper sheds further light on the relationships between the current-value Hamiltonian, net national product (NNP), and sustainability condition in the context of a cake-eating economy. It shows that the usual interpretation of the current-value Hamiltonian as the maximum sustainable...
