Constructing the MIA Dataset

Chapter Three introduces the Measure of International Authority (MIA) index on delegation and pooling. The first two sections describe how the authors aggregate scores for individual IO bodies at particular stages of decision making in particular decision areas to estimate delegation and pooling at the level of an international organization. In short, it explains the algorithm that produces delegation and pooling scores. The third section presents descriptive statistics comparing delegation and pooling over time, across IOs, and across decision areas. The chapter concludes with tables that summarize the extent of delegation and pooling, in the aggregate and by decision area, for each of seventy-six IOs in the MIA dataset. The scores tap annual variation from 1950 (or date of IO creation) to 2010 (or date of IO death).
