Жасыл талғамдар, сенімдер және портфельдер: синтетикалық инвесторлардың куәліктері - Синди Хе, Лубос Пастор

Біз ХБМ-ны «жасыл дәмдерді» анықтау үшін синтетикалық зерттеу респонденттері, кірістілікті бағалау, портфельдік қаржы бөлу және 480 бөлшек және 60 институционалдық инвесторлардың инвестициялық мотивтері ретінде пайдаланамыз. Бөлшек саудамен салыстырғанда, мекемелер сыртқы қысымды сылтаурата отырып, портфельдің жасыл иілуі туралы әлсіз талғам туралы хабарлайды. Сондықтан неғұрлым жасыл көлбеу жасыл желекке неғұрлым күшті дәм көрсетпеуі керек. Бөлшек талғамдар негізінен саяси қажеттілікке, тип пен географияның институционалдық дәмдеріне байланысты. Жағдайға байланысты пікірлер әр түрлі болады

We use LLMs as synthetic survey respondents to elicit green tastes, return beliefs, portfolio allocations, and investment motives from 480 retail and 60 institutional investor identities. Compared with retail, institutions report weaker tastes yet greener portfolio tilts, citing outside pressure. A greener tilt therefore need not indicate a stronger taste for greenness. Retail tastes depend mostly on political affiliation, institutional tastes on type and geography. Beliefs differ across the three ESG dimensions, with high-governance portfolios expected to outperform. We reconstruct survey responses under 2014--2025 information environments using date-masked information modules shuffled across years. Tastes vary little over time, but beliefs about green portfolios become more pessimistic after 2020. The two reconstructed series relate to different real-world data: tastes to measures of green demand, beliefs to measures of attention.

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. To enable systematic comparisons, we develop a pipeline that extracts the responsibilities from job adarXiv cs.CY (Computers and Society)

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.
