    Abstract: This paper examines how combinations of ancestral cultural norms are associated with women’s empowerment across ethnic groups worldwide. Linking Demographic and Health Surveys to ancestral traits from the Ethnographic Atlas, we develop a hybrid supervised– unsupervised approach combining Partial Least Squares with k-means clustering to identify multidimensional normative configurations. We identify five probabilistic regimes spanning the empowerment gradient. Severe disempowerment is associated with an accumulation of restrictive norms, while religious norms and women’s role in agriculture distinguish higherempowerment environments within otherwise broadly patriarchal configurations. Further up the gradient, contrasts concern first hierarchical social institutions, then kinship structures and the loosening of patriarchal arrangements, before less traditional, more gender-neutral configurations become widespread at the highest levels of empowerment. The salience of norms varies with the configurations in which they are embedded, revealing strongly non-monotonic patterns. These findings remain robust to accounting for contemporary socioeconomic conditions and to a range of sensitivity checks. Overall, the analysis provides a global mapping of ancestral normative environments associated with women’s agency and helps identify the configurations most closely related to severe intrahousehold inequality.

  2. By: Thomas Delcey (LEDi - Laboratoire d'Economie de Dijon [Dijon] - UBE - Université Bourgogne Europe); Aurélien Goutsmedt (ICHEC - Brussels Management School [Bruxelles], UCLouvain - Université Catholique de Louvain = Catholic University of Louvain); Alexandre Truc (GREDEG - Groupe de Recherche en Droit, Economie et Gestion - UNS - Université Nice Sophia Antipolis (1965 - 2019) - CNRS - Centre National de la Recherche Scientifique - UniCA - Université Côte d'Azur)
    Abstract: This article demonstrates how unsupervised quantitative methods can enrich the history of economic thought. Using the largest English-language corpus ever assembled for the field—nearly 260, 000 economics journal articles from 1900 to 2009 with citation data—we analyze the evolution of the concept of rationality. Combining large language model–based semantic analysis with bibliometric and network methods, we identify and cluster discussions of rationality across time and scales, such as the emergence of a social view of rationality, the circulation of bounded rationality, and the emergence of behavioral economics. We provide an open-source interactive tool to support transparency and reuse.
