Policies of lowering carbon demand may aggravate rather than alleviate climate change (green paradox). In a two-period three-country general equilibrium model with finite endowment of fossil fuel one country enforces an emissions cap in the first or second period. When that cap is tightened the...

This paper contributes to the discussion on Separate Accounting versus Formula Apportionment in the corporate income taxation of multinational enterprises (MNEs). The innovation of the analysis is that we consider a general equilibrium tax competition model with an endogenously determined world...

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...

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 for...

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,...

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...

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...

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 provides a rationale for subsidizing green (renewable) energy production. Within a multi-country model where energy is produced with mobile capital in green and dirty production, we investigate the countries' decentralized choice of emissions taxes and green energy subsidies. Without...

This paper points to the important role which the elasticity of aggregate capital supply with respect to the net rate of return to capital plays for the efficiency of policymaking in a decentralized economy with mobile capital and spillovers among jurisdictions. In accordance with previous...
