In a multi-country general equilibrium economy with mobile capital and rigid-wage unemployment, countries may differ in capital endowments, production technologies and rigid wages. Governments tax capital at the source to maximize national welfare. They account for tax base responses to their...

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...

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 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....

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...

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...

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...

We analyse tax competition with corporate profit taxes in a common market where tax revenues are allocated according to an apportionment formula. As a general rule, tax competition is sharper the higher is the tax elasticity of the apportionment formula which, in turn, depends on the properties...
