Carlos Álvarez‐Nogal and Christophe Chamley recently published an article in the Economic History Review on ‘Debt policy under constraints: Philip II, the Cortes, and Genoese bankers’. In this note, we show that several claims in their article are very similar to earlier research results, published or circulated long before Álvarez‐Nogal and Chamley's original submission, by ourselves and other scholars (section I). These results are repeated without attribution or even mention of the earlier work. In addition, we show that what Álvarez‐Nogal and Chamley present as new quantitative insights are actually replications of earlier results of ours (section II). Finally, Álvarez‐Nogal and Chamley misrepresent our contributions, as well as those of several other scholars (section III).
