Welcome to the homepage of the Measure of International Authority (MIA) dataset. MIA contains estimates of the delegation and pooling of authority (1950-2010) as well as the scope of the policy portfolio for 76 international governmental organizations (1950-2017). The MIA estimates are annual. We are working on an update through 2020.

Two books accompany the measurement project. If you are planning to use the data or the documents posted here, please cite these works.

1. The first sets out a measure of delegation and pooling for 76 IOs and publishes profiles for 45 IOs (1950-2010). Profiles for the remaining 31 IOs are released on this page (see below).

2. The second develops a measure of IO policy scope — the range of policies that an IO is responsible for (1950-2017).

                                            Data and Documentation

DELEGATION AND POOLING: The zip file contain three files:

  • MASTER dataset with raw data by IO-year for 374 coding variables (matrix=3295 x 374)
  • Do file to extract delegation and pooling variables
  • DP dataset with aggregate delegation and pooling variables, delegation and pooling by decision area, and delegation and pooling by decision stage (matrix=3295 x 19)
    MIA data set: MIA_authority (version of 06/11/19)

POLICY SCOPE: The zip file contains the following files:

  • Policy scope manual: A. Concept, coding, descriptives + B. codebook + C. list of IOs
  • Two excel files that document for each IO how policy scope is scored and why.
  • Policy dataset (core, flanking) in stata15
    MIA policy data set: MIA_policy (version of 06/11/19)

      *The research was funded by the European Union’s Advanced European Research Council grant # 249543 “Causes and Consequences of Multilevel Governance.”



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  of Volume III discusses how we conceptualize international authority and press down the abstract concept into concrete indicators. Chapter Two explains how we apply the coding scheme (Appendix II) to particular IOs, and illustrates how we deal with gray cases. Chapter Three scales up indicators to two dimensions of international authority, delegation and pooling.

Unpublished profiles of 31 IOs

Some people have asked access to the IO profiles that were not published in our OUP (2017) book. The list of IOs is here, and the profiles are available here. Please note that these profiles were not intended for publication: they are shorter, secondary literature is more lightly referenced, and they have not been copy-edited. These profiles record our coding judgments by linking assessments to primary sources. All excel files are downloadable from the website via the drop-down menu.

Excel files with coding by IO

The coding for each IO is summarized in a single excel per IO, which we group by geographical scope. The excel file follows the coding scheme, which taps the structure and composition of IO bodies and their role in decision making at decision stages and across decision areas. You can download the excel files for all 76 IOs here.

When you consult the coding for a specific IO, it is useful to have two additional documents at hand: the coding scheme, and the excel manual, which takes you through the excel file step-by-step. If you just want to skim the excel, please know that columns summarize scoring on specific components of the IO decision process, whereby each column refers to a question in the coding scheme, and that rows refer to the IO bodies or decision modes that affect IO decision making on a specific component in a given year. We start a new set of rows for each year in which a change is detected in one of the columns.
