Measurement of International Authority (MIA)

The dataset sets out a measure of authority for 76 international organizations (IOs) from 1950, or the time of their establishment, to 2010. The IOs considered are regional (e.g. the EU, Andean Community, NAFTA), crossregional (e.g. Commonwealth of Nations, the Organization of Islamic Cooperation), and global (e.g. the UN, World Bank, WTO). We introduce estimates for the scope and depth of authority exercised by international governments along two conceptual dimensions: delegation and pooling; describe broad trends in IO authority; and present the evidence that we have gathered in 47 IO profiles.
