We study a growth model with an environmental asset which is a source of utility and an input to consumption and production. The stock of this asset follows its own ecological dynamics, which are affected by economic activity. We study the implications of an approach to ranking sequences of...

Many firms go reduce their impact on the environment more than is legally required - that is, they overcomply with environmental regulations. There is clearly a cost to this, so there has to be a benefit too. I suggest that firms are consciously internalizing external costs, with a view to...

We review the properties of the conventional static measure of changes in economic welfare, national income, in a dynamic economy. We show that it is possible to establish attractive welfare properties by rather simple arguments and that this variable can be estimated from current data. Its...

Green growth is about making growth processes resource-efficient, cleaner and more resilient without necessarily slowing them. This paper aims at clarifying these concepts in an analytical framework and at proposing foundations for green growth. The green growth approach proposed here is based...

Does the present concern about sustainability raise fundamentally new issues for economics, or is it dealing with problems already on our agenda? There are two points that are central to sustainability: a concern for what happens in the long-run, and a respect for the constraints that the...

In this article, we focus on the potential of governmental authorities dedicated to management of ecosystem services. We argue that the creation of such Ecosystem Service Districts (ESDs) will improve the efficient provision of services necessary for human welfare. At the moment, when agencies...

Sustainability is an important, influential but elusive concept. I review concepts related to sustainability in earlier literature, and then summarize and synthesize recent work on sustainablity by Chichilnisky (1993), Beltratti, Chichilnisky and Heal (1994) and Heal (1993). This provides a...

We study paths which involve optimal use of a renewable resource under several alternative definitions of optimality, including the discounted utilitarian, Chichilnisky's, the Rawlsian and the green golden rule. Initially we consider an economy where the only good is the resource: subsequently,...

We address the problem of optimal use of renewable resources under a variety of assumptions both about the nature of the economy in which these resources are embedded and about the objective of that economy. In this second respect, we are particularly interested in investigating the consequences...
