Governance Indicators : Where Are We, Where Should We Be Going?
(World Bank, Washington, DC, 2007-10)Scholars, policymakers, aid donors, and aid recipients acknowledge the importance of good governance for development. This understanding has spurred an intense interest in more refined, nuanced, and policy-relevant indicators of governance. In this paper we review progress to date in the area of measuring governance, using a simple framework of analysis focusing on two key questions: (i) what do we measure? and, (ii) whose views do we rely on? For the former question, we distinguish between indicators measuring formal laws or rules 'on the books', and indicators that measure the practical application or outcomes of these rules 'on the ground', calling attention to the strengths and weaknesses of both types of indicators as well as the complementarities between them. For the latter question, we distinguish between experts and survey respondents on whose views governance assessments are based, again highlighting their advantages, disadvantages, and complementarities. We also review the merits of aggregate as opposed to individual governance indicators. We conclude with some simple principles to guide the refinement of existing governance indicators and the development of future indicators. We emphasize the need to: transparently disclose and account for the margins of error in all indicators; draw from a diversity of indicators and exploit complementarities among them; submit all indicators to rigorous public and academic scrutiny; and, in light of the lessons of over a decade of existing indicators, to be realistic in the expectations of future indicators. -

Governance Matters VI : Aggregate and Individual Governance Indicators, 1996-2006
(World Bank, Washington, DC, 2007-07)This paper reports on the latest update of the Worldwide Governance Indicators (WGI) research project covering 212 countries and territories and measuring six dimensions of governance between 1996 and 2006: voice and accountability, political stability and absence of violence, government effectiveness, regulatory quality, rule of law, and control of corruption. This latest set of aggregate indicators are based on hundreds of specific and disaggregated individual variables measuring various dimensions of governance taken from 33 data sources provided by 30 different organizations. The data reflect the views on governance of public sector, private sector, and nongovernmental organization experts, as well as thousands of citizen and firm survey respondents worldwide. The paper also explicitly reports the margins of error accompanying each country estimate. These reflect the inherent difficulties in measuring governance using any kind of data. It finds that even after taking margins of error into account, the WGI permit meaningful cross-country comparisons, as well as monitoring progress over time. In less than a decade, a substantial number of countries exhibit statistically significant improvements in at least one dimension of governance, while other countries exhibit deterioration in some dimensions. The decade-long aggregate indicators, together with the disaggregated individual indicators, are available in a newly-redesigned website at www.govindicators.org. -

Governance Matters V : Aggregate and Individual Governance Indicators for 1996–2005
(World Bank, Washington, DC, 2006-09)The authors report on the latest version of the worldwide governance indicators, covering 213 countries and territories and measuring six dimensions of governance from 1996 until end-2005: voice and accountability, political stability and absence of violence, government effectiveness, regulatory quality, rule of law, and control of corruption. The latest indicators are based on hundreds of variables and reflect the views of thousands of citizen and firm survey respondents and experts worldwide. Although global averages of governance display no marked trends during 1996-2005, nearly one-third of countries exhibit significant changes [for better or for worse] on at least one dimension of governance. Three new features distinguish this update. (1) The authors have moved to annual reporting of governance estimates. This update includes new governance estimates for 2003 and 2005, as well as minor backward revisions to biannual historical data for 1996-2004. (2) The authors are, for the first time, publishing the individual measures of governance from virtually every data source underlying the aggregate governance indicators. The ready availability of the individual data sources underlying the aggregate governance indicators is aimed at further enhancing the transparency of the methodology and of the resulting aggregate indicators, as well as helping data users and policymakers identify specific governance challenges in individual countries. (3) The authors present new evidence on the reliability of expert assessments of governance which, alongside survey responses, form part of the aggregate measures of governance. -

Government Matters III : Governance Indicators for 1996-2002
(World Bank, Washington, DC, 2003-08)The authors present estimates of six dimensions of governance covering 199 countries and territories for four time periods: 1996, 1998, 2000, and 2002. These indicators are based on several hundred individual variables measuring perceptions of governance, drawn from 25 separate data sources constructed by 18 different organizations. The authors assign these individual measures of governance to categories capturing key dimensions of governance and use an unobserved components model to construct six aggregate governance indicators in each of the four periods. They present the point estimates of the dimensions of governance as well as the margins of errors for each country for the four periods. The governance indicators reported here are an update and expansion of previous research work on indicators initiated in 1998 (Kaufmann, Kraay, and Zoido-Lobat 1999a,b and 2002). The authors also address various methodological issues, including the interpretation and use of the data given the estimated margins of errors. -

Governance Matters VII : Aggregate and Individual Governance Indicators 1996-2007
(World Bank, Washington, DC, 2008-06)This paper reports on the latest update of the Worldwide Governance Indicators (WGI) research project, covering 212 countries and territories and measuring six dimensions of governance between 1996 and 2007: Voice and Accountability, Political Stability and Absence of Violence/Terrorism, Government Effectiveness, Regulatory Quality, Rule of Law, and Control of Corruption. The latest aggregate indicators are based on hundreds of specific and disaggregated individual variables measuring various dimensions of governance, taken from 35 data sources provided by 32 different organizations. The data reflect the views on governance of public sector, private sector and NGO experts, as well as thousands of citizen and firm survey respondents worldwide. The authors also explicitly report the margins of error accompanying each country estimate. These reflect the inherent difficulties in measuring governance using any kind of data. The authors also briefly describe the evolution of the WGI since its inception, and show that the margins of error on the aggregate governance indicators have declined over the years, even though they still remain non-trivial. The authors find that even after taking margins of error into account, the WGI permit meaningful cross-country comparisons as well as monitoring progress over time. In less than a decade, a substantial number of countries exhibit statistically significant improvements in at least one dimension of governance, while other countries exhibit deterioration in some dimensions. These aggregate indicators, spanning more than a decade, together with the disaggregated individual indicators, are available at www.govindicators.org. -

The Worldwide Governance Indicators Project : Answering the Critics
(World Bank, Washington, DC, 2007-03)The Worldwide Governance Indicators, reporting estimates of six dimensions of governance for over 200 countries between 1996 and 2005, have become widely used among policymakers and academics. They have also attracted some explicit written criticisms. In this short paper the authors synthesize 11 critiques offered by four recent papers. They then refute them as either conceptually incorrect or empirically unsubstantiated.
