In this paper we first critically review conventional environmental economics. We conclude that the standard theory offers too narrow a perspective for many real world problems and that many theories are not empirically tested. Consequently, environmental economics is at risk of producing aeroplanes without engines. Next, we welcome and discuss some recent(More)
Cross-country estimations of the Environmental Kuznets Curve (EKC) to empirically analyze the relationship between income and pollution have generally assumed a common structure for all countries. Since this latter feature is not supported by economic theory, this paper uses the Random Coefficient Model proposed by Swamy (1970) and empirically estimates(More)
We present a theoretical approach to study the screening charge density n(s)(r) and the respective stopping coefficient Q for hydrogen and helium at the low velocity limit. An electron gas, with electronic density n(e), is used to represent the conduction or valence electrons of the target material. Solving numerically the Schrödinger radial equation, for a(More)
While tourism brings many benefits to islands, it can also cause negative effects, especially when tourism development is a disorganised process, with significant environmental impacts. This has been the case of Easter Island: the recent, uncontrolled growth in tourist numbers together with social and political tensions, are signs of a socioeconomic process(More)
