The Common Scale

Abstract

This paper is the synthesis and capstone of a four-case comparative programme built to test whether value sovereignty — the framework this author drew from Zimbabwe's lithium turn — is a general theory of African mineral value capture or an artefact of the single case that produced it. Across Botswana's diamonds, Ghana's gold, Nigeria's oil and the Democratic Republic of the Congo's cobalt, arranged by design across two regional blocs and the full institutional range from the continent's strongest state to among its weakest, the programme applied one analytical template and one verdict vocabulary. This paper places all five cases — the four tests and the Zimbabwean anchor — on that common scale; consolidates the four refinements the hardest cases forced upon the framework; and reports three findings visible only in comparison: that raw export is the continental default from which value sovereignty is everywhere a later and deliberate departure; that the rootedness of captured value in the producing community lags its capture by the national exchequer in every case without exception; and that value sovereignty has two separable dimensions — command over the market and capture of the processing chain — which may be asserted in sequence rather than together. The programme thereby answers, structurally and on the evidence, the fair charge that the framework was reverse-engineered to fit Zimbabwe. It closes by stating the matured framework as a standing reference for the series, and by making explicit the deeper purpose the four cases serve: to refuse the single story of African political economy — the story of curse, of dependency, of the continent as the object of other people's theories — not by denying its truths but by insisting on its incompleteness, and by authoring, from within the African case, an account of how a nation climbs the ladder of its own value.
