Efficient nonanthropocentric nature protection
Eichner, Thomas; Pethig, Rüdiger - 2004
This paper analyzes nature protection by a social planner under different ?utilitarian? social welfare functions. For … efficient allocations when social welfare is anthropocentric (only consumers have positive welfare weights), and when social … welfare is nonanthropocentric (all species have positive welfare weights).

Economic Land Use, Ecosystem Services and Microfounded Species Dynamics
Eichner, Thomas; Pethig, Rüdiger - 2004
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...

Optimal pest control in agriculture
Christiaans, Thomas; Eichner, Thomas; Pethig, Rüdiger - 2005
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 behaviour of individual organisms a short-run ecosystem equilibrium is defined and characterized that depends on the farmer's use...

A micro-level 'consumer approach' to species population dynamics
Christiaans, Thomas; Christiaans, Thomas; Pethig, Rüdiger - 2005
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....

Nonlinear production, abatement, pollution and materials balance reconsidered
Pethig, Rüdiger - 2005
In the environmental economics literature the standard approach of modeling nonlinear production and abatement processes is to treat waste emissions "simply as another factor of production" (Cropper and Oates 1992). That approach doesn't map the materials flow involved completely and hides,...

An analytical foundation of the ratio-dependent predator-prey model
Eichner, Thomas; Pethig, Rüdiger - 2004
Predator-prey models of the Lotka-Volterra type and their refinements describe predator-prey interactions taking populations as basic units of analysis. In contrast to these macro models we derive interdependent population growth functions of a predator and a prey species from a micro ecosystem...

Carbon leakage, the green paradox and perfect future markets
Eichner, Thomas; Pethig, Rüdiger - 2009
Policies of lowering carbon demand may aggravate rather than alleviate climate change (green paradox). In a two-period three-country general equilibrium model with finite endowment of fossil fuel one country enforces an emissions cap in the first or second period. When that cap is tightened the...

EU-type carbon emissions trade and the distributional impact of overlapping emissions taxes
Eichner, Thomas; Pethig, Rüdiger - 2009
example we show that export-import reversals and welfare reversals are possible. …
