The past decade has seen increased attention on questions related to taxation and revenue in developing countries, from both policymakers and researchers. However, the quality of available cross-country tax and revenue data has remained seriously deficient, leading to potentially flawed research results and misplaced policy advice. Given our shared interests in supporting good research and good policy, UNU-WIDER is extremely happy to be partnering with the International Centre for Tax and Development (ICTD) to host the Government Revenue Dataset (GRD). An important motivation behind the creation of the dataset was concern about the quality and transparency of data from the IMF: publicly available data had significant limitations, while the private data used in much internal IMF research was not usually available to other researchers, and appeared to contain significant errors. The immediate goal was thus to provide better and more transparent data to researchers. A longer-term target has been to encourage international organizations, led by the IMF, to invest in higher-quality revenue data and to make that data publicly available.
