The use and prevalence of JEL code categorization is wide in the field of economics, but what do JEL code classifications actually tell us? And are they used with consistency by academics in the field? Utilizing a dataset of articles published in the American Economic Review from 1990-2008, we investigate whether there is heterogeneity in JEL codes assignments between authors and editors. We find that there is. A secondary goal of this paper is to explore overall thematic trends in JEL code usage over the past four and a half decades. One result is that JEL category M: Business Economics, in particular, appears to be thematically and spatially distinct from much of the rest of the published literature in the top general interest journals in the field.
