This paper analyzes the formation of self-enforcing climate agreements, or stable climate coalitions, when all countries have the option to fight climate change by purchasing (the right to extract) fossil-energy deposits. First, we consider the stand-alone deposit purchase policy and then...

In the world economy with interdependent markets for fossil fuel and deposits, some coalition of countries fights climate change by purchasing and preserving fossil fuel deposits, which would be exploited otherwise. If the coalition’s policy parameters are the demand and supply of deposits...

In Harstadś (2012) model, climate damage only hits one group of countries, called the coalition, and the coalitionś climate policy consists of capping own fuel demand and supply combined with the purchase of fossil fuel deposits for preservation. Harstadś Theorem 1 states that if the deposit...

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...

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...

This paper studies the market allocation in an economy where material is used for producing a consumption good, then recycled and finally landfilled, and where a recycling firm has market power. The material content constitutes an aspect of green product design and affects the recycling costs....

In this paper the welfare state is considered as insurance device. Redistributive taxation reduces the variance of life- time risk. Behind a veil of ignorance with regard to future position in society, agents decide in a two-parametric expectation/standard deviation-approach about labour supply...
