This article argues that the discipline of economics consists of two subdisciplines: heterodox and mainstream economics. Being distinct bodies of knowledge, it is possible that the processes of building scientific knowledge are different enough so to generate distinctly different referencing and citation practices. Therefore, a specific impact contribution score is necessary for ranking heterodox journals in terms of their contribution to building heterodox economics. If properly developed such a metric could also be used to produce a single overall quality-equality ranking of mainstream and heterodox journals. Utilizing citation data and peer evaluations of 62 heterodox economics journals, a research quality measure is developed and then used to rank the journals. The measure is then used in conjunction with the SSCI five-year impact factor to produce a comparative research quality-equality rankings of the 62 heterodox and the 192 mainstream journals in the SSCI.
