In this paper we develop a micro ecosystem model whose basic entities are representative organisms which behave as if maximizing their net offspring under constraints. Net offspring is increasing in prey biomass intake, declining in the loss of own biomass to predators and Allee's Law applies....

Harvesting of prey biomass is analyzed in an integrated ecological-economic system whose submodels, a predator-prey ecosystem and a simple economy, are microfounded dynamic general equilibrium models. These submodels are interdependent because the ecosystem responds to harvesting - through the...

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