This paper sets up a multiregional dynamic framework by combining the optimal savings model with investment adjustment costs and the spatially disaggregated model with Dixit-Stiglitz structure in the modern sector. Because of increasing product diversity on the dynamic equilibrium path, the...

The production of bioenergy is considered to be a promising energy source for a sustainable energy mix and it is politically promoted in many countries. With the exception of Brazilian ethanol, bioenergy not competitive to fossil energy sources, and therefore needs to be subsidised. Several...

Because of large economic and environmental asymmetries among world regions and the incentive to free ride, an international climate Regime with broad participation is hard to reach. Most of the so far proposed Regimes base on an allocation of emission rights that is to be perceived as fair....

It is often feared that tax competition might lead to a “race to the bottom”. The consequence of a decline of tax rates on capital income would be shrinking capital income tax revenues and difficulties for national governments to perform their usual tasks. The paper analyzes what happened to...

What determines the foreign aid effort of donor countries? We review the existing literature on donors’ aid budgets and examine which of the suggested variables robustly determine aid effort, measured as Official Development Assistance (ODA) as a share of gross national income. More...

National labour market institutions interact across national boundaries when product markets are global. Labour market policies can thus entail spill-overs, a fact widely ignored in the academic literature. This paper studies the effects of wage subsidies in an international duopoly model with...

For many years there have been political intentions to harmonize tax rates in Europe. As to capital income taxation, competition is often seen to be especially harmful. Facing a high degree of international capital mobility, every country is expected to reduce its tax rate in order to attract...

The policy instruments for emissions reductions will be an integral part of a Post Kyoto Climate Regime. In this paper we compare a harmonized international carbon tax to a cap and trade system with different allocation rules for the emission caps. The caps are based either on the requirement...

We carry out a detailed sensitivity analysis of border carbon adjustment (rates) by applying a global Computable General Equilibrium (CGE) GTAP7-based model. We find different incentives for the regions in the climate coalition to raise carbon-based border tax rates (BTAX) above the standard...

Quantification of CO2 emissions embodied in China's trade is important for an informed debate on whom to blame for the recent rise in Chinese emissions or the calculation of border carbon adjustments. Applying input output techniques, we calculate these emissions in (1) a standard model, (2) a...
