The impact of scarcity and abundance in food chains on species population dynamics
Eichner, Thomas; Pethig, Rüdiger - 2003
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...

A Microfoundation of Predator-Prey Dynamics
Eichner, Thomas; Pethig, Rüdiger - 2003
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...

Profit Tax Competition and Formula Apportionment
Pethig, Rüdiger; Wagener, Andreas - 2003
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...

This common benchmark for all taxes is … zero, in particular, those producer prices involve distortive - and non-corrective! - emission subsidies. Internalization … of environmental externalities means to set these virtual emission subsidies equal to zero. It is also shown that …
