Coase Seetings Negishi: Property Rights, Social Vights, and Distributional Affairs in Climate Economic Economics (Саймон Ф. Лэнг, Мэтью Д. Гордон, Мэтью Джей. Мысық

Біз климаттың өзгеруінің экономикалық модельдерінде әл-ауқат салмақтарын айқындауға меншік құқығына негізделген тәсілді әзірлеп жатырмыз. "Ластауға құқық" немесе "ластаудың болмау құқығы" бар-жоғына қарамастан, заң шығарушы органдар, соттар және климат жөніндегі халықаралық келіссөздер жиі даулайды. Біз бұл мүліктік құқықтар ұғымы көпжақты қоғамдық игіліктерге қолданылатын «әл-ауқаттың жағалаулық салмақтарын» анықтау үшін негіз қалайша негіз бола алатынын көрсетеміз. Бөлу мәселелері позитивті талдау, шарттар негізінде шешіледі

We develop a property-rights based approach for defining welfare weights in economic models of climate change. Whether there is a "right to pollute" or a "right to no pollution" is increasingly contested in legislatures, courts, and international climate negotiations. We show how these notions of property rights can provide the basis for "Coasean welfare weights" that are applicable in multilateral public goods settings. Distributional questions are addressed through positive analysis, conditional on property rights, rather than normative views about redistribution. The implied transfers are consistent with a bargained solution over the net benefits of addressing climate change and reflect the value of property rights over emissions. The approach defines efficient allocations that generate Pareto improvements, in contrast to commonly used Negishi weights. We implement the approach in a global integrated assessment model to quantify what countries have at stake in ongoing political and legal debates about emissions-related property rights.

ИсследованияSame Facts, Different Remedy: Linguistic Profiling and Arbitrariness in LLM and System One DecisionsarXiv:2611.08995v1 Announce Type: new Abstract: Large language models are increasingly used to resolve consumer complaints, and the way complainants write varies with age, education and socioeconomic status (SES). We audit three remedy-decision systems using sociolinguistic rewrites of US consumer financial complaints that are instructed to preserve every fact: two generative LLMs that return a single label (GPT-4o-mini and GPT-5-mini) and a probabilistic "System One" model that returns a distriarXiv cs.CY (Computers and Society)

We examine how the prevalence and content of work activities in online job postings change in association with activity-level measures of AI exposure, derived from Copilot and Claude usage.

These interactions generate digital traces, prompting efforts to infer mental health and psychosocial states. As large language models become more capable of reasoning about conversations and interpersonal dynamics, a fundamental question remains nonetheless: what can models actually "know" about an individual's psychological experience farXiv cs.CY (Computers and Society)

However, identity formation in the wake of such empowerment remains understudied.
