It is shown that the thermodynamic law of conservation of mass, the so-called Materials-Balance-Principle, implies that the marginal product as well as the average product of a material resource input are bounded from above. This means that the Inada conditions, one of the standard assumptions...

In their seminal paper on production, consumption and externalities (AER, 1969), Ayres and Kneese initiated a research program on comprehensive analysis and management of residuals and pollution based on two pillars: the study of the residuals-generating materials flow subject to the mass...

This paper addresses the issue of environmental and ecological impacts of nutrient flows within and between countries by reviewing and presenting data on nutrient balances and global nutrient movements. The results for nutrient depletion in agricultural soils during 1996-1999 show that in most...

In this paper we present a new approach to evaluate the environmental efficiency of decision making units. We propose a model that describes a two-stage process consisting of a production and an end-of-pipe abatement stage with the environmental efficiency being determined by the efficiency of...

The relationship between trade and material flows is examined by viewing theglobal economy from the perspective of international material-product chains(MPC). The international MPC covers the complete lifecycle of a material or aproduct in two or more regions, including extraction, production,...

A model framework, SIMBIOSES, is presented which describes economic activities and relatedmaterial, substance and energy flows in a multi-region and multi-sector economic system. Theconceptual design of the framework is discussed in relation to current issues on dematerializationand...

Die Modellierung und Analyse von betrieblichen Stoffstromsystemen gewinnt in der Praxis zunehmend an Bedeutung. Die Methode der Stoffstromnetze erweisen sich hierbei als mächtiges Instrumentarium für die Durchführung verschiedenster Analysen. Durch die saubere methodische Trennung von Mengen-...

Rather than contributing to the proliferation of ad hoc environmental indicators and accounting systems this paper addresses the physical-monetary dichotomy in measuring the interactions between environment and economy by focusing on two systematic approaches which appear to become international...

Vorwort: Das sozio-ökonomische System ist ein Subsystem des übergreifenden natürlichen Systems. Diese Feststellung gehört zum Selbstverständnis der Ökologischen Ökonomen. In diesem Sinne wurde von Dieterich, Messner und Strassert in Heft 1/1999 der Beiträge und Berichte eine Plattform...
