SUMMARY:Zackary DUNIVIN (University of Stuttgart) - "What is the role of social identity in LLMs?"
DESCRIPTION:Sociology Seminar \nTime: 10:00 am – 11:00 am\nDate: 25th of March\nRoom : 3049 \n  \nZackary DUNIVIN (University of Stuttgart) – “What is the role of social identity in LLMs?” \nAbstract :  \nFrontier language models don’t simply generate text. LLMs perform sociocultural sensemaking\, drawing on shared cultural patterns (e.g.\, roles\, norms\, social identity) to interpret situations and determine appropriate responses. This poses a governance problem. Identity can be necessary for ethical and competent judgment in context\, yet the dominant paradigm for regulating identity\, bias mitigation\, treats it mainly as a contaminant to suppress and evaluates systems largely via end outputs. That leaves underspecified how models should decide when identity is relevant\, how to reason under uncertainty and unequal power\, and how to justify and revise their stance. I call this problem bias negotiation: the procedural regulation of identity-conditioned judgments of relevance\, inference\, and justification. Bias negotiation matters for justice because a positive role for sociocultural reasoning is required to recognize and potentially remediate structural inequities. But it is equally implicated in core model functionality as sociocultural competence is critical in systems that operate across heterogeneous institutions and cultural contexts. Drawing on structured dialogues with multiple deployed chatbots\, I identify recurring negotiation repertoires and failure modes\, and conclude with specifications that support implementation and procedural evaluation design. \n  \nOrganizers: \nEtienne OLLION (Pôle sociologie CREST)\n \nPaola TUBARO (Pôle sociologie CREST) \nNicolas JULIA (Pôle sociologie CREST) \nPatrick PRÄG (Pôle sociologie CREST) \nSponsors:\nCREST \n

SUMMARY:Sophie BADE (Royal Holloway) - "Open-ended Matching with and without Markets"
DESCRIPTION:Séminaire Microéconomie : Tous les mercredis\nHeure : 12h15 – 13h30\nDate : 25/03/2026\nSalle : 3001 \nSophie BADE (Royal Holloway) – “Open-ended Matching with and without Markets” \nCV : Suppose agents are to be matched to objects and arrive over time without a definite terminal date. Although the set of core matchings can then be empty\, a transfinite version of the top trading algorithm shows that Pareto-optimal weak-core matchings always exist. Optimal matchings face a difficulty however: some of the agents linked by chains of trades may have lifespans that do not overlap\, thus obstructing their trades. To address this problem\, we let matchings be implemented via competitive markets. Competitive equilibria always exist and any matching in the core can be completely implemented. Moreover full core equivalence\, where allocations are in the core if and only if they can be completely implemented\, holds for a dense set of models. The extended algorithm also yields a strategyproof mechanism\, comparably to the finite model. \nOrganisateurs :  \nJulien COMBE (Pôle d’Economie du CREST)\n​​​​​​​​​​​​Yves Le YAOUANQ (Pôle d’Economie du CREST) \nCommanditaires :\nCREST \n

SUMMARY:Marshall TAYLOR (New Mexico State University) - "Meaningful Geometries: Towards a More Reliable Analysis of Culture using Word Embeddings"
DESCRIPTION:Sociology Seminar \nTime: 2:00 pm – 3:00 pm\nDate: 25th of March\nRoom : 3049 \n  \nMarshall TAYLOR “Meaningful Geometries: Towards a More Reliable Analysis of Culture using Word Embeddings” \nAbstract :  \nTo what extent do text corpora reflect gender or social class biases? In computational social science\, answering these types of questions often involves analyzing semantic dimensions in word embedding spaces. While powerful\, this approach relies on “anchor” words that lack standardized reliability assessments. I introduce a new\, structure-agnostic metric to fill this gap. I validate the metric at the word-level using expert- and crowd-sourced dictionaries and at the document-level using expert-annotated social media posts. I also provide simulation-based heuristic baselines to facilitate effect size interpretation and null hypothesis testing. \n  \nEtienne OLLION (Pôle sociologie CREST)\n \nPaola TUBARO (Pôle sociologie CREST) \nNicolas JULIA (Pôle sociologie CREST) \nPatrick PRÄG (Pôle sociologie CREST) \nSponsors:\nCREST \n
