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...

In this paper we consider a competitive economy with flows of materials from extraction via recycling to landfilling which exhibits distortions due to pollution, external landfilling costs and inefficient product design. The allocative impact of tax-subsidy policies aiming at internalizing the...

In a multi-country model with mobile capital and global pollution this paper analyzes the stability of self-enforcing environmental agreements (IEAs) when the coalition formed by the signatory countries plays Nash. In accordance with previous environmental literature we show that there exists a...

In the basic model of international environmental agreements (IEAs) (Barrett 1994, Rubio and Ulph 2006) extended by international trade, self-enforcing - or stable - IEAs may comprise up to 60 % of all countries (Eichner and Pethig 2013). But these IEAs reduce total emissions only slightly...

Capital tax competition is known to result in inefficiently low tax rates and an undersupply of public goods. The provision of public goods and with it the wel- fare of all countries can be enhanced via tax coordination. Based on the standard Zodrow-Mieszkowski-Wilson tax-competition model this...

This paper analyzes the efficient emissions taxation in economies with individuals who are morally motivated to reduce their emissions footprint. They are heterogenous with respect to their morality and their consumption preferences. We distinguish between the concepts of moral and conventional...

In this paper we reexamine the issue of allocating a natural resource 'material' that is extracted, used for producing a consumption good, recycled, and that may cause environmental damage when it is finally landfilled without prior waste treatment. The 'material' explicity enters the analytisis...
