In a neoclassical world the existence of non-zero transaction costs, nonconvex technologies, public goods and so on creates inefficiencies which can be dealt with by various institutions. But, institutions can create inefficiencies of their own. This volume addresses the issue of efficiency and...

In an integrated dynamic general equilibrium model of the economy and the ecosystem humans and wildlife species compete for land and prey biomass. We introduce a competitive allocation mechanism in both submodels such that economic prices and ecosystem prices guide the allocation in the economy...

This paper studies within a multi-country model with international trade the stability of international environmental agreements (IEAs) when countries regulate carbon emissions either by taxes or caps. Regardless of whether coalitions play Nash or are Stackelberg leaders the principal message is...

Itaya et al. (2014) study the conditions for sustainability and stability of capital tax coordination in a repeated game model with tax-revenue maximizing governments. One of their major results is that the grand tax coalition is never stable and sustainable. The purpose of this note is to prove...

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...

We analyse tax competition with corporate income taxes in a common market where tax revenues are allocated according to an apportionment formula. Generally, tax competition is sharper (i.e., equilibrium tax rates are lower) the more tax-elastic is the apportionment formula. This depends on the...

This paper analyzes nature protection by a social planner under different ‘utilitarian’ social welfare functions. For that purpose we construct an integrated model of the economy and the ecosystem with explicit consideration of nonhuman species and with competition between human and nonhuman...
