What factors determine whether it is optimal with one or more technologies in a decarbonized road transport sector, and what policies should governments choose? We investigate these questions theoretically and numerically through a static, partial equilibrium model for the road transport market....

This paper provides a quantitative comparison of the main architectures for an agreement on climate policy. Possible successors to the Kyoto protocol are assessed according to four criteria: economic efficiency; environmental effectiveness; distributional implications; and their political...

In the spirit of Harberger, we apply a dynamic computable general equilibrium (CGE) model and estimate the excess burden stemming from the tax-induced distortion in the allocation of capital across the corporate and the non-corporate sectors in Germany. In doing so, we perform a counterfactual...

This paper studies the design of the optimal non linear taxation in an economy where longevity varies across agents, and depends on three factors: longevity genes, health investment and farsightedness. Provided earnings, farsightedness and genes are correlated, governmental intervention can be...

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...

Pension benefit rules depend on individual history far more than taxes do, and age plays a much larger role in pension determination than in tax determination. Apart from some simulation studies, theoretical studies of optimal tax design typically contain neither a mandatory pension system nor...

This paper reconsiders the effects of dividend taxation. Particular attention is paid to the form of the equity trap, that is, the extent to which cash paid to the shareholders must be taxed as dividends. Our analysis shows that Sinn's (1991) criticism of the well-known King and Fullerton (1984)...

We examine international cooperation on technological development as a supplement to, or an alternative to, international cooperation on emission reductions. R&D should be increased beyond the non-cooperative level if (i) the technology level in one country is positively affected by R&D in other...

This paper investigates the welfare costs of unilateral versus internationally coordinated emission permit policies in a two-country overlapping generations model with producer carbon emissions. We show that, for a net foreign debtor country, the domestic welfare costs of a unilateral domestic...

The usually assumed two categories of costs involved in climate change policy analysis, namely abatement and damage costs, hide the presence of a third category, namely adaptation costs. This dodges the determination of an appropriate level for them. Including adaptation costs explicitly in the...
