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...

Departing from Hotelling's assumption of fixed and known reserves, this paper develops an economic model of additions to proven reserves that explicitly incorporates the effects of expected resource price, cumulative reserves development, and technological progress on reserve additions. The...

The study tests the popular belief that Democrats (and more generally, liberals) are “green” while Republicans (more generally, conservatives) are “brown”, for several measures of California air quality indicators. We employ two alternative econometric identification strategies on...

In a dynamic model of a risk-neutral competitive firm which can lower its pollution emissions per unit of output by building up abatement capital stock, we examine the effect of a higher pollution tax rate on abatement investment both under full certainty and when the timing or the size of the...

We develop and estimate an econometric model of the relationship between several local and global air pollutants and economic development while allowing for critical aspects of the socio-political-economic regime of a State. We obtain empirical support for our hypothesis that democracy and its...

The paper focuses 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...

We develop and estimate an econometric model of the relationship between several local and global air and water pollutants and economic development while allowing for critical aspects of the socio-political-economic regime of a State. We obtain empirical support for our hypothesis that democracy...

We study a firm's optimal lobby behavior and its effect on investment in pollution abatement capital. We develop a dynamic framework where a representative firm can invest in both abatement and lobby capital in response to a possible future increase in pollution tax. We show that when the firm...

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...
