A main reason for our present climate problems are not the basic economical requirements of man but the exponential increasing world population and their ever growing demand for luxury far beyond the necessary basic economical needs. It is suggested to put the world's attention on the basic...

Endangered species are in predator/prey, mutualistic, competitive, or other types of relationships with many other species that share their habitat. Understanding these ecological relationships is an important part of designing endangered species policies. We employ a general equilibrium model...

This paper studies the interaction between two dynamic domains, (1) an evolutionary biological system ('the environment') whose behaviour determines the availability of a resource stock, and (2) an industry where access to the resource stock is determined by the outcome of a patent race. The...

Watersheds and irrigation systems have the characteristic of connecting people vertically by water flows. The location of users along these systems defines their role in the provision and appropriation of water which adds complexity to the potential for cooperation. Verticality thus imposes a...

Resource-based models of species competition have been introduced recently as an alternative to the classical theory based on the Lotca-Volterra methodological approach to species competition. We consider economic management of an ecosystem for a Tilman model of mechanistic resource-based...

This paper examines the welfare implications of rising temperatures. Using a standard VAR, we empirically show that a temperature shock has a sizable, negative and statistically significant impact on TFP, output, and labor productivity. We rationalize these findings within a production economy...

The relationship between economic growth and the environment is, and will always remain, controversial. Some see the emergence of new pollution problems, the lack of success in dealing with global warming and the still rising population in the Third World as proof positive that humans are a...

Environmental risks may comprise the most important policy-related application of the economics of risk and uncertainty. Many biases in risk assessment and regulation, such as the conservatism bias in risk assessment and the stringent regulation of synthetic chemicals, reflect a form of...

We clarify the definition and interpretation of “sustainability economics” (Baumgärtner and Quaas 2010) in response to recent comments by van den Bergh (2010), Bartelmus (2010) and others. For that sake, we distinguish between general and specific definitions of sustainability and...
