Who Learned What? Revisiting IMF and World Bank Engagement in the 1982 Mexican Debt Crisis

The 1982 Mexican debt crisis was a watershed in Latin America’s economic history that triggered Latin America’s broader debt crisis and the ensuing “lost decade.” Much of the existing literature portrays the International Monetary Fund (IMF) and the World Bank as enforcers of a pre-established, austerity-centred agenda during Mexico’s restructuring process. This article seeks to advance a different claim: not only did IMF and World Bank officials lacked a clear and unified ideology but, instead, experimented, adapted, and learned in real time as the crisis unfolded. At the same time, they also exchanged lessons across departments and between the two institutions, and later transposed practices to other Latin American debtors. To develop this argument, the article examines the 1982 Mexican crisis to identify who learned within the IMF and the World Bank, when the learning process occurred, and, finally, in which specific policy domains it took place. It then moves beyond the Mexican case to trace not only how lessons travelled across departments and between the two institutions, but also how these practices were subsequently transposed to later cases, particularly Brazil. Drawing on a large corpus of recently declassified internal documents from both organizations, the study adopts a mixed qualitative and computational design that combines archival research with NLP-based methods, including topic modelling and a newly developed “learning index,” to map changing diagnoses, instruments, and internal debates over time. The article contributes to scholarship that challenges deterministic accounts of the IMF’s and the World Bank’s roles in Latin America’s debt crises, while also offering a replicable methodological framework that can be applied beyond this case.
