Though it is currently benefiting from a renewal of interest, the economic history of Africa raises intense methodological controversies that are echoed in two books recently published by Morten Jerven, Poor Numbers and Africa: Why Economists Get It Wrong. A large proportion of these controversies relate more generally to the differences between economists and historians, at least in terms of their dominant practices. In its quest for the institutional “fundamentals” of economic development, much research in this field is content to work with a summary and imperfect base of data, an approach that Jerven is right to criticize. Analyses often suffer from an insufficient knowledge of social contexts, and compress historical time between a “before” and a “now.” They also rely on debatable statistical assumptions. Nevertheless, though extant archives present limitations that are both qualitative (the sources are predominantly colonial) and quantitative, a modest renaissance remains a possibility and would offer more space for better controlled comparative analyses.
