The EUSANCT Dataset covers sanction threats and imposed sanctions by the European Union, the United States and the United Nations from 1989-2015. Disaggregating the sanctioning efforts from the EU, the US and the UN, the EUSANCT Dataset shows that the imposition and effectiveness of sanctions varies widely between these senders. EUSANCT is a tool for sender-focused analyses and related examinations – and allows scholars to analyze the conditions under which the liberal senders have employed a wide range of economic measures during the entire post-Cold War era. Moreover, this comprehensive dataset traces the evolution and effectiveness of economic coercion over time. The research community will thus find the database useful to analyze standard questions about the onset, side-effects and effectiveness of sanctions.
