Economists have a good understanding of intra-economic interdependence and a mature methodology of modeling it. Ecologists focus on the complex and sensitive interactions of species in ecosystems. This paper's objective is to suggest a new micro-foundation of ecosystem analysis based on economic...

In dem vorliegenden Beitrag untersuchen wir auf der Grundlage eines statischen allgemeinen Gleichgewichtsmodells die Effizienz verschiedener Gebuehrenkonzepte einer Abfall-Management-Organisation. Diese wird von den Produzenten, die fuer die Verwertung und/oder Entsorgung der Verpackungsabfaelle...

This paper examines a Waste Management Organisation's (WMO) pricing options to implement the Pareto-efficient allocation in an economy where materials are first extracted, then used for producing a consumption good and finally recycled or landfilled. The WMO is established by the producers who...

In der vorliegenden Studie ueberpruefen wir verschiedene Gebuehrenstrategien der Dualen System Deutschland AG (DSD) darauf hin, ob sie die pareto-effiziente Allokation in der Abfallwirtschaft implementieren. Dabei greifen wir auf eine disaggregierte Modelloekonomie zurueck, in der Material...

The Mekong River is the dominant geo-hydrological structure in mainland Southeast Asia, originating in China and flowing through or bordering Myanmar, Laos, Thailand, Cambodia, and Vietnam. Whereas water resources in the wet season are more than adequate to fulfill basin needs, there are...

The nature of energy and material resources in an endogenous growththeory framework isclarified. This involves three modifications of the conventionaltheory. Firstly, multiple feedbackmechanisms or “growth engines” are identified. Secondly, a productionfunction distinguishesbetween resource...

Recent advances in evolutionary theory have important implications for environmental economics. A short overview is offered of evolutionarythinking in economics. Subsequently, major concepts and approaches inevolutionary biology and evolutionary economics are presented andcompared. Attention is...

Optimal harvesting of prey in a predator–prey ecosystem is studied under the condition that the existence of the predator has value. Predators (birds) and humans (fishers) compete for prey (shellfish). The behavior of the system is studied and conditions for optimal control are deduced....

We analyze how the threat of a potential future regime shift affects optimal management. We use a simple general growth model to analyze four cases that involve combinations of stock collapse versus changes in system dynamics, and exogenous versus endogenous probabilities of regime shift. Prior...

The Dasgupta-Heal-Solow-Stiglitz model of capital accumulation and resource depletion poses the following sustainability problem: is it feasible to sustain indefinitely a level of consumption that is bounded away from zero? We provide a complete technological characterization of the...
