The government effectiveness index is a ranking of state capacity developed by the World Bank Group. It measures the quality of public services, civil service, policy formulation and implementation, and the credibility of a government's commitment to improving or maintaining these aspects. The index includes 193 countries, each scored from -2.5 (less effective) to 2.5 (more effective).[1] It is part of a broader set of government quality indicators.[2][3]
The World Bank releases the government effectiveness index as one of six worldwide governance indicators. The others are voice and accountability, political stability, regulatory quality, the rule of law, and control of corruption.[4] Daniel Kaufmann of the Natural Resource Governance Institute and Aart Kraay of the World Bank Development Research Group produce these indexes.[4] They consider these six indexes as dimensions of governance.[5]
