Over the past four years I have led the construction of the ICTD Government Revenue Dataset (GRD), which is the best available source of cross-country government tax and revenue data.  Relative to other sources it offers both dramatically improved coverage and much greater analytical accuracy. 

Access the Working Paper describing the data here.

Access the newly updated data (August 2015) here.

UNU-WIDER and the ICTD are hosting an international conference in Mozambique for research employing the new data in March 2016.  More information and call for papers here.

UNU-WIDER will be partnering with the ICTD to host the new data.  More information here.
