We examine the impact of a unilateral carbon tax in developed countries focusing on the expected size of carbon leakage (an increase in emissions in non-taxing regions as a result of the tax) and the effects on leakage of border tax adjustments. We start by analyzing the problem using a simple...

In the absence of an international agreement on climate policy, unilateral carbon abatement creates two problems: It tends to have a detrimental effect on domestic competitiveness, and it leads to an increase in carbon emissions abroad (leakage). This paper analyses two policies that have...

The analysis focuses on carbon-motivated border tax adjustment (CBTA). CBTA are tariffs applied to imports designed to avoid drawbacks of emission reduction policies when only one or few regions (the abating regions) implement them. Through CBTA the abating regions level out different treatment...

Ambitious unilateral EU environmental policy has raised concerns about adverse competitiveness implications for European energy-intensive and export-oriented sectors. We analyze the economic and environmental implications of two different measures to address these concerns in the EU Emission...

For a large global economy with normal goods, and an unequal world income distribution, we consider the endogenous formation and stability of an international environmental agreement (IEA) under nationally determined contributions (NDCs). Nations share green R&D efforts and enjoy R&D spillovers...

This paper examines international cooperation on technological development as an alternative to international cooperation on GHG emission reductions. In order to analyze the scope of cooperation, a three-stage technology agreement formation game is solved. First, countries decide whether or not...

As the most inhospitable continent on Earth, Antarctica has more than 90% of its territory covered with ice and contains around 70% of all potable water in the world. Its proximity to South America is especially relevant to Brazil, which includes it in the country's strategic surrounding area....

This paper examines international cooperation on technological development as an alternative to international cooperation on GHG emission reductions. It is assumed that when countries cooperate they coordinate their investments so as to minimize the agreement costs of controlling emissions and...

Being the most inhospitable continent in Earth, Antarctica has more than 90% of its territory covered with ice and contains around 70% of all drinkable water in the world. Its proximity to South America turns this region into especially relevant to Brazil, being included to the country's...
