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...

In a multi-country general equilibrium economy with mobile capital and rigid-wage unemployment, countries may differ in capital endowments, production technologies and rigid wages. Governments tax capital at the source to maximize national welfare. They account for tax base responses to their...

This paper analyzes optimal linear taxes on labor income and savings in a standard two-period life-cycle model with endogenous leisure demands in both periods and non-insurable income risks. Households are subject to skill shocks in both periods of the life-cycle. We allow for completely general...

We study the incidence of carbon-reduction and green-energy promotion policies in an open fossil-fuel importing general equilibrium economy. The focus is on mixed price-based or quantity-based policies. Instruments directed toward promoting green energy are shown to reduce also carbon emissions...

To analyze the optimal social insurance package, we set up a two-period life-cycle model with risky human capital investment in which the government has access to labor taxation, education subsidies and capital taxation. Social insurance is provided by redistributive labor taxation. Moreover,...

Internalizing the global negative externality of carbon emissions requires flattening the extraction path of world fossil energy resources (= world carbon emissions). We consider governments having sign-unconstrained emission taxes at their disposal and seeking to prevent world emissions from...

In recent years, differences between traditional and green parties have been leveled with respect to climate protection. We show that this partial convergence in party platforms can be explained by international climate agreements, effectively reducing greenhouse gas emissions. We set up a...

There is a growing concern that governments lose substantial corporate tax revenue because of profit shifting through transfer-pricing and thin-capitalization strategies. Existing literature studies profit shifting and transfer pricing separately. In practice, the choice of debt-to-asset ratios...

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...

We demonstrate that the choice of the transfer price and its effect on intra-firm trade and investment depends on the probability of detection and thus on the measure, on which tax authorities base their audit. A policy implication of the paper is that it should be preferable to condition audits...
