Abstract:
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 NGO experts, as well as thousands of citizen and firm survey respondents worldwide. We also explicitly report the margins of error accompanying each country estimate. These reflect the inherent difficulties in measuring governance using any kind of data. We 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.

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. We also explicitly report the margins of error accompanying each country estimate. These reflect the inherent difficulties in measuring governance using any kind of data. We 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. We 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.

Abstract:
Kaufmann, Kraay, and Mastruzzi 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-Lobaton 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.

This paper - a joint product of the Global Governance Department, World Bank Institute, and Macroeconomics and Growth, Development Research Group - is part of a larger effort in the Bank to generate and analyze worldwide governance indicators, and to assess the causes and consequences of governance.

Abstract:
Kaufmann, Kraay and Mastruzzi present the newly updated estimates of six dimensions of governance covering 209 countries and territories for five time periods: 1996, 1998, 2000, 2002 and 2004. These indicators are based on several hundred individual variables measuring perceptions of governance, drawn from 37 separate data sources constructed by 31 different organizations. The authors assign these individual measures of governance to categories capturing key dimensions of governance, and use an unobserved component 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 error for each country for the four periods. These margins of error are not unique to perceptions-based measures of governance, but are an important feature of all efforts to measure governance, including objective indicators. In fact, the authors provide examples of how individual objective measures provide an incomplete picture of even the quite particular dimensions of governance that they are intended to measure.

The paper also analyzes in some detail changes over time in our estimates of governance; provide a framework for assessing the statistical significance of changes in governance; and suggest a simple rule of thumb for identifying statistically significant changes in country governance over time. The ability to identify significant changes in governance over time is much higher for our aggregate indicators than for any individual indicator. While they find that the quality of governance in a number of countries has changed significantly (in both directions), the authors also provide evidence suggesting that there are no trends, for better or worse, in global averages of governance. Finally, the authors interpret the strong observed correlation between income and governance, and argue against recent efforts to apply a discount to governance performance in low income countries.

Abstract:
This paper reports on the 2009 update of the Worldwide Governance Indicators (WGI) research project, covering 212 countries and territories and measuring six dimensions of governance between 1996 and 2008: Voice and Accountability, Political Stability and Absence of Violence/Terrorism, Government Effectiveness, Regulatory Quality, Rule of Law, and Control of Corruption. These aggregate indicators are based on hundreds of specific and disaggregated individual variables measuring various dimensions of governance, taken from 35 data sources provided by 33 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. We also explicitly report the margins of error accompanying each country estimate. These reflect the inherent difficulties in measuring governance using any kind of data. We find that even after taking margins of error into account, the WGI permit meaningful cross-country comparisons as well as monitoring progress over time.

Abstract:
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.

Abstract:
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.

Abstract:
We contribute to the field of urban governance and globalization through an empirically-based exploration of determinants of performance of cities. We construct a preliminary worldwide database for cities, containing variables and indicators of globalization (at the country and city level), city governance, city performance (access and quality of service delivery), as well as other relevant city characteristics. This city database, encompassing hundreds of cities worldwide, integrates existing data with new data gathered for this research project. We present a very simple conceptual framework and a set of hypotheses, and then test them econometrically. The findings suggest that good governance and globalization (at both the country as well as at the city level) do matter for city-level performance in terms of access and quality of delivery of infrastructure services. We also find that globalization and good city governance are significantly related with each other. Furthermore, the evidence suggests that there are particular and complex interactions between technology choices, governance and city performance, as well as evidence of a non-linear relationship between city size and performance. We conclude pointing to the need for expanding the database and the econometric framework, as well as to more general future research directions and policy implications emerging from this initial empirical investigation in the field of governance and the city.

Abstract:
We are increasingly cognizant of the limits to large cross-country empirical studies in trying to understand in-depth a particular country reality, in ways useful for advice. At the same time, merely relying on a single country account at a particular point in time ignores the historical and comparative cross-country perspective. Worse, an in-depth investigation of a single issue within a country begs the question of whether such particular issue may be fundamental for the country's growth and development relative to other determinants, or not. Further, drawbacks exist from excessive reliance on narrow empirical approaches, or on mere qualitative narrative.

Consequently, the approach undertaken here for the case of Bolivia is of an integrated nature, combining the following strands: i) an historical perspective from the twin standpoints of the evolution of the enterprise and government sectors over the past half century; ii) an in-depth review of the literature on explanations of Bolivia's performance; iii) an empirical analysis of the country's enterprise sector performance on the basis of a detailed firm-level survey conducted recently in 80 countries, and, iv) an empirical analysis of Bolivia's public agencies based on a survey of public officials in Bolivia working in over 100 institutions. To provide an additional element of comparability, we also utilize cross-country governance indicators.

Abstract:
Six dimensions of governance are estimated covering 199 countries and territories for four periods: 1996, 1998, 2000, and 2002. The indicators are based on several hundred individual variables measuring perceptions of governance drawn from 25 data sources constructed by 18 organizations. These individual measures are assigned to categories capturing key dimensions of governance. An unobserved-components model is used to construct six aggregate governance indicators in each of the four periods. Point estimates of the dimensions of governance are provided as well as the margins of errors for each country for the four periods. Methodological issues are also addressed, including tests for potential biases, and the interpretation and use of the data, given the estimated margins of errors for the indicators. The data and a Web-based graphical interface are available online at .
