PhD thesis

Economic Sanctions, Enforcement, and the Question of Effectiveness

The United States, United Kingdom, and European Union are currently among the world’s leading users of economic sanctions. While great attention has been paid to sanctions design within and across these jurisdictions, less attention has been given to sanctions enforcement. In light of increasing political interest in sanctions enforcement, this dissertation proposes to analyse the link between sanctions enforcement and effectiveness, from geostrategic and normative perspectives, and to undertake an empirical inquiry into how enforcement practises contribute to the overall effectiveness of sanctions. The inquiry focuses on enforcement in the United Kingdom and the EU, while drawing on empirical information from the U.S. experience. The EU, which has a decentralised regime for enforcement, will be examined through cases studies of several Member States and an evaluation of proposed initiatives that may give the EU institutions a greater role in enforcement.
