- Arndt, Christiane and Charles Oman (2006). Uses and Abuses of Governance Indicators (Paris: OECD Development Centre).
- A slim, highly readable volume arguing that composite perceptions-based indicators of governance in developing countries would be less open to abuse if such indices fully disclosed their methodology, scoring criteria, and countries' scores. Although the authors acknowledge that no single governance indicator is the answer, they nevertheless suggest that improving the transparency of governance indicators will go a long way towards making them more relevant to users.
