Economics-related ICT research has moved from the fringes of the discipline to penetrate all of its branches. It is, therefore, not a separate economics sub-discipline. It is also unlikely to become part of an 'ICT or Internet Research' proto-discipline. Instead, it should be seen as only one part of a bigger agenda toward a proper 'information and knowledge economics' and possibly a future proto-discipline of a 'unified theory of information and knowledge' or a meta-discipline of information sciences.
This is the post-print version of a short article for the Special Issue: ICT Research and Disciplinary Boundaries: Is “Internet Research” a Virtual Field, a Proto-Discipline, or Something Else?”(Guest Editor: Nancy K.
