In an integrated economy-ecosystem model humans choose their land use and leave the residual land as habitat for three species forming a food chain. The size of habitat determines the diversity and abundance of species. That biodiversity generates, in turn, a flow of ecosystem services with...

Based on economic methodology we model an ecosystem with two species in predator-prey relationship: mice feed on grain and grain feeds on a resource. With optimizing behavior of individual organisms a short-run ecosystem equilibrium is defined and characterized that depends on the farmer's use...

In this paper we reexamine the issue of allocating a natural resource 'material' that is extracted, used for producing a consumption good, recycled, and that may cause environmental damage when it is finally landfilled without prior waste treatment. The 'material' explicity enters the analytisis...

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...

In a dynamic general equilibrium model we explictly consider the relationship between the product attributes 'durability' and 'recyclability'. Both efficiency and sustainability aspects are taken into account. It turns out (a) that durability may be inefficient even in a perfectly competitive...

Under the assumption of imperfect competition in a durable good industry, the present paper investigates the efficient regulation of solid waste which causes environmental damage at the end of the product's life. It turns out that the second-best waste tax falls short of the marginal...

This paper studies the market allocation in an economy where material is used for producing a consumption good, then recycled and finally landfilled, and where a recycling firm has market power. The material content constitutes an aspect of green product design and affects the recycling costs....

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...
