He was also the chairman of the most comprehensive study ever undertaken on Namibia, "Namibia: Perspectives for National Reconstruction and Development", which was undertaken by the United Nations Institute for Namibia in pursuance of the mandate given to it by the United Nations General Assembly. This study covered all aspects of socio-economic reconstruction and development for independent Namibia. This study came to be known as the "Blue Bible", referring to the colour of its cover, among the researchers and planners of Namibia. Indeed, this study provided the blueprint for setting up the new government in independent Namibia.
