The scores produced in the Measure of International Authority (MIA) are akin to Lego blocks that summarize coherent ingredients of international governance that can be aggregated in different ways for different purposes. Chapter One discusses the theoretical-conceptual underpinnings of the Measure of International Authority (MIA). It explains how we conceptualize international authority and press down the abstract concept into concrete indicators. Chapter Two sets out how we apply the coding scheme (Appendix II) and produce scores for particular IOs, on components of decision making or institutional structure, and across years. It sets out rules that underpin our interpretations while keeping a sharp eye on opaque concepts, awkward cases, and borderline decisions. It is intended to help the user traverse the gap between indicator and observation. Chapter Three scales up these indicators (or scores) to two dimensions of international authority, delegation and pooling. The first sections of this chapter shows how we aggregate scores for delegation and for pooling respectively. In the third section, we provide a glimpse on delegation and pooling over time and across decision areas.
