James in collaboration with Eivind Tveter developed a thinkpiece on agglomeration and transport appraisal. The thinkpiece identifies the areas where TAG may need to be developed to ensure it reflects state of the art thinking in this area. Particular areas of interest relate to the treatment of public sector workers, localisation and urbanisation (and long distance agglomeration), consumption benefits (amenity value) of agglomerations, and the functional form of the Access To Economic Mass variable.
