The ECJ Judgment on the Extensions of the ETS to Aviation: An Economist's Discontent
Few EU decisions have caused more international outcry than the extension of the EU Emissions Trading System (ETS) to apply to aviation. The directive was legally challenged by US airlines before a UK court, which referred the case to the European Court of Justice (ECJ) for a preliminary ruling concerning the compatibility of the directive with international law. This paper discusses the argumentation by the ECJ and the Advocate General from an economic perspective. Such an analysis is warranted in light of the fact that the contested measure is an economic regulation, the international laws that are invoked have clear economic objectives, and the ECJ judgment and the opinion by the Advocate General at least partly rely on economic concepts and mechanisms. An economic analysis also seems warranted from a legal point of view since the quality of the judgment and of the opinion presumably depend on the soundness of their economic reasoning. It is found that the argumentation by the legal authorities is highly questionable in important parts, when viewed from an economic perspective.
Can border carbon taxes fit into the global trade regime? Bruegel Policy Brief 2013/06, 9 December 2013
One complement to domestic climate policies could be the regulation of carbon dioxide emissions arising during the production of imported products. Such ‘border carbon adjustments’ (BCAs) are said to have several benefits, but are also severely criticised. This Policy Brief highlights some weaknesses in the standard argumentation for BCAs. But there is an alternative argument for border carbon measures, based on the fact that countries expose each other to climate externalities. The reformulated argument is economically more convincing, and provides a more convincing justification for the extraterritorial feature of border carbon measures. However, there are also several important factors mitigating against the implementation of such measures, including the risk that these measures will be used for protectionism.

Fiscal Transparency in EU Accession Countries Progress and Future Challenges
This paper discusses the findings of fiscal transparency reports on standards and codes (ROSCs) for most EU accession candidate countries. Emphasis is given to the need to establish effective and accountable medium-term budget frameworks to establish policy credibility and anchor adjustment programs to meet EU fiscal goals. Adoption of budgeting and accounting standards consistent with the IMF Government Finance Statistics Manual 2001 framework will also help link budget decisions to EU standards of fiscal reporting. More consistent and comprehensive coverage of off-budget activities is needed for assessing fiscal risk and sustainability. Finally, local government issues need to be addressed by many of these countries since EU fiscal goals are set with reference to general government. Progress in all of these areas can be monitored by keeping fiscal ROSC assessments up to date.
