This paper studies the formation of self-enforcing global environmental agreements in a world economy with international trade and two groups of countries that differ with respect to fuel demand and environmental damage. It investigates whether the signatories threat to embargo (potential) free...

In a multi-country model with interconnected markets for fossil fuel and deposits some countries fight climate damage by purchasing and preserving fossil fuel deposits, which would be exploited otherwise. We analyze the effectiveness of such a deposit policy, when that policy stands alone or is...

This paper studies the formation of self-enforcing global environmental agreements in a world economy with international trade and two groups of countries that differ with respect to fuel demand and environmental damage. It investigates whether the signatories’ threat to embargo (potential)...

Ecological systems (ecosystems, for short) are complex systems of interacting species, plants and animals, where each of the species consists of individual organisms that interact with organisms of the same or other species in various ways: they compete for scare resources and they are involved...

The population dynamics in a food chains are derived from a sequence of short- run equilibria of an ecosystem where predator species demand prey biomass, supply own biomass to their predators and are assumed to behave as if they maximize net biomass intake. Introducing prices as scarcity...

Predator-prey relationships account for an important part of all interactions between species. In this paper we provide a microfoundation for such predator-prey relations in a food chain. Basic entities of our analysis are representative organisms of species modelled similar to economic...

Using a general equilibrium model where material is first extracted, then used for producing a consumption good, recycled and finally treated to reduce environmental damage, we study efficiency-restoring policies, when one or more of the constituent markets are inactive. The material is modeled...

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...
