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...

According to many observers, the world is currently getting riskier along many of its dimensions. In this paper we analyse how the welfare state, i.e., social insurance that works through redistributive taxation, should deal with this trend. We distinguish between risks that can be insured by...

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....

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...

A small open economy produces a consumer good, green and black energy, and imports fossil fuel at an uncertain price. Unregulated competitive markets are shown to be inefficient. The implied market failures are due to the agents’ attitudes toward risk, to risk shifting and the uniform price...

Ogawa et al. (2006) analyze capital tax competition in a fixed-wage approach and show that the original results of Zodrow and Mieszkowski (1986) are not preserved in the presence of unemployment. In the present paper we challenge this view and investigate capital tax competition for some...

This paper examines strategic incentives to subsidize green energy in a group of countries that operates an international carbon emissions trading scheme. Welfare-maximizing national governments have the option to discriminate against energy from fossil fuels by subsidizing green energy,...

In the present paper we extend the classical tax-competition framework of Zodrow and Mieszkowski (1986) by modelling involuntary unemployment and by allowing for labour taxation as a second source of public funds. For a large class of production functions (including CES), it turns out that tax...

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...
