Scientific expertise suggests that mitigating extreme world-wide climate change damages requires avoiding increases in the world mean temperature exceeding 2° Celsius. To achieve the two degree target, the cumulated global emissions must not exceed some limit, the so-called global carbon...

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,...

The European Union fulfills its emissions reductions commitments by means of an emissions trading scheme covering some part of each member state's economy and by national emissions control in the rest of their economies. The member states also levy energy/emissions taxes overlapping with the...

In earlier literature, the suggested Pareto improvements in pay-as-you-go (PAYG) systems have relied on the presence of externalities or the possibility of intragenerational redistribution. We show that neither assumption is necessary in an economy with intergenerational trade in a fixed factor...

A relatively high labor-intensity in government-run entities need not imply slack in their organization. Rather, it is a rational reaction to various forms of wage tax advantage that the public sector has over private firms. Even though an unequal tax treatment of public and private sectors...

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...

We consider taxation by a Leviathan government and by a utilitarian government in the presence of heterogeneous locations within a country, when migration from one country to another is and is not possible. In a closed economy, a utilitarian government may transfer income from the poor to the...

Oates and Schwab (1988) consider an economy with mobil capital and jurisdictions that suffer from local pollution. They show that welfare-maximizing jurisdictions implement the first-best, if they take prices as given and have at their disposal a capital tax and an environmental standard....

We propose a dynamic general equilibrium model with human capital accumulation to evaluate the economic consequences of compulsory services (such as military draft or social services). Our analysis identifies a so far ignored dynamic cost arising from distortions in time allocation over the...

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...
