Major conceptual contributions of a number of Nobel-laureates in putting forth a framework linking the citizenry's right to know and access to information with development, have already had a major influence in various fields. However, implementation of transparency-related reforms on the ground remains checkered around the globe. Further, in contrast with other dimensions of governance -such as rule of law and regulatory burden-, there is a gap between the extent of the conceptual contributions in the transparency field and the progress on its measurement and empirical analysis, which has been wanting. This paper is a contribution attempting to partly fill these empirical and policy-related gaps. The paper contributes to empirics by undertaking an initial construction of a transparency index for 194 countries based on over twenty 20 independent sources. An Unobserved Component Model (UCM) was used to generate the country ratings and the margins of error. The indices comprise an aggregate transparency index with two sub-components: economic/institutional transparency, and political transparency.The results emphasize variance. Exemplary transparency is not the exclusive domain of a particular region, and there are transparency-related challenges in countries in each region and income categories. Further, there is significant within-country variation, with large differences in performance between economic/institutional and political dimensions of transparency. Mindful of the challenges in inferring causality, we also find that transparency is associated with better socio-economic and human development indicators, as well as with higher competitiveness and lower corruption.Much progress can be attained without requiring inordinate amount of resources, since transparency reforms can be substantial net 'savers' of public resources, and often can serve as a more efficient and less financially costly substitute to creating additional regulations and/or regulatory or governance bodies. A number of concrete examples of specific transparency-related reforms within a strategic framework are provided.
