As large language models (LLMs) like GPT become increasingly prevalent, it is essential that we assess their capabilities beyond processing. This paper examines the economic rationality of by instructing to make budgetary decisions in four domains: risk, time, social, and food preferences. We measure assessing consistency GPT’s with utility maximization classic revealed preference theory. find are largely rational each domain demonstrate higher score than those human subjects a parallel...
Abstract Background Most reported sporotrichosis cases came from South American countries, the USA, India and Japan. This mycosis is also endemic in Northeast China. However, situation not clear for international researchers due to lack of large series English. Objectives To report analyse 457 cases. Methods Retrospective study diagnosed by fungal culture at First Hospital Jilin University 1 January 2007 31 December 2009. Results In this series, male: female ratio was 1:1.42. Mean age 41.2...
Abstract The propensity to take risk underpins a wide variety of decision-making behavior, ranging from common ones such as asking for directions and trying out new restaurant more substantial economic decisions involving, instance, one's investment or career. Despite the fundamental role attitude in economy, its genetic basis remains unknown. Using an experimental economics protocol combined with classical twin strategy, we provide first direct evidence heritability attitude, at 57%. We do...
Prospect theory proposes the hypothesis that people have diminishing sensitivity in valuing increases size of monetary outcomes, for both gains and losses. For decision-making under risk, this implies a tendency to be risk-tolerant over losses while being generally risk averse gains. We offer neurochemistry-based model valuation hypothesis. Specifically, we propose dopamine tone modulates towards serotonin Consequently, higher would yield more concave function convex Using neurogenetics...
Decision making often entails longshot risks involving a small chance of receiving substantial outcome. People tend to be risk preferring (averse) when facing significant gains (losses). This differentiation towards underpins the markets for lottery as well insurance. Both and insurance have emerged since ancient times continue play useful role in modern economy. In this study, we observe subjects' incentivized choices controlled laboratory setting, investigate their association with widely...
Trust underpins much of social and economic exchanges across human societies. In experimental economics, the Game has served as workhorse for study trust in a controlled incentivized setting. Recent evidence using intranasal drug administration, aka 'sniffing', suggests that oxytocin (OT) can function hormone facilitating other affiliative behaviors. Here we hypothesized baseline plasma OT is biomarker partially predicts degree trustworthiness observed game. Using large sample 1,158...
Deficits in social behavior mice lacking the CD38 gene have been attributed to impaired secretion of oxytocin. In humans, similar deficits are associated with autistic spectrum disorder (ASD), for which genetic variants pinpointed as provisional risk factors. We sought explore, an vitro model, feasibility theory that restoring level ASD patients could be potential clinical benefit. transcription is highly sensitive several cytokines and vitamins. One these, all-trans retinoic acid (ATRA), a...
Andreoni and Sprenger (2012a,b) observe that utility functions are distinct for risk time preferences, show their findings consistent with a preference certainty. We revisit this question in an enriched experimental setting which subjects make intertemporal decisions under different conditions. The observed choice behavior supports separation between attitude substitution rather than further several models, including Epstein Zin (1989); Chew (1990); Halevy (2008) exhibit such can account the...
We conduct a series of experiments and document robust behavioral pattern whereby people behave more morally in uncertain environments than degenerate deterministic ones. show that this is weakened when the moral implication behavior diminished or uncertainty pertains to others rather oneself. These findings are incompatible with standard models respect dominance. propose mechanism based on anxiety aspect act as if their can help deliver better outcome. further delve into complexity arrive...
In experimental economics, the preference for reciprocal fairness has been observed in controlled and incentivized laboratory setting of ultimatum game, which two individuals decide on how to divide a sum money, with one proposing share while second deciding whether accept. Should proposal be accepted, amount is divided accordingly. Otherwise, both would receive no money. A recent twin study shown that inferred from responder behavior heritable, yet its neurogenetic basis remains unknown....
Abstract This study explores the relationship between competitiveness and stress. In Experiment 1, we observe a higher response of cortisol—the primary stress hormone—to computation task coupled with tournament than to piece rate. Moreover, more competitive subjects exhibit responses their less counterparts in tasks under both 2, find that exogenously induced does not significantly affect competitiveness. Overall, our findings reveal an important trade‐off rate terms implications on design...
Significance Game theory is used throughout the social and biological sciences to study behavior in interactions. Recent research suggests an important role for dopamine neurotransmitter system these types of decisions. This a competitive game how people varied their decision-making processes related differences set genes that carry out functions required dopaminergic functioning. We found differentially expressed separate brain regions influenced distinct components people’s surprising...
Purpose – This experimental economics study using brain imaging techniques investigates the risk-ambiguity distinction in relation to source preference hypothesis (Fox & Tversky, 1995) which identically distributed risks arising from different sources of uncertainty may engender distinct preferences for same decision maker, contrary classical economic thinking. The use enables sharper testing implications models decision-making including Chew and Sagi's (2008) axiomatization...
The occurrence of positive selection in schizophrenia-associated GABRB2 suggests a broader impact the gene product on population fitness. present study considered possibility cognition-related involvement by examining association with psychosis and altruism, respectively representing psychiatric psychological facets social cognition. Four single nucleotide polymorphisms (SNPs) were genotyped for quantitative trait analyses population-based studies. Psychosis was measured either Positive...
Abstract We examine source dependence in the setting of effort provision. Our first experiment elicits preference over uncertain piece rate schemes to perform a real‐effort task. second after receiving an gift. vary probability winning and familiarity natural sources uncertainty. show that subjects are averse unfamiliar for moderate or high probability, but less so low probability. Moreover, exhibits more insensitivity under compared with familiar source. findings support validity...
In a graying world, there is an increasing interest in correlates of aging, especially those found early life. Leukocyte telomere length (LTL) emerging marker aging at the cellular level, but little known regarding its link with poor decision making that often entails being overly impatient. Here we investigate relationship between LTL and degree impatience, which measured laboratory using incentivized delay discounting task. sample 1,158 Han Chinese undergraduates, observe steeper...
This paper examines the causal impact of poverty reduction interventions on social preferences poor. A multifaceted program in China provides a setting for use fuzzy regression discontinuity design. The design compares households with base-year income just below preset criterion, who were more likely to receive treatment, above criterion. Five years after program’s launch, we conducted lab-in-the-field experiment measure distributional household heads. Combining quasi-random variation from...
It is widely recognized that psychological stress impairs performance for elite athletes, yet direct evidence scarce when it comes to high-stakes competition because measuring real-time without interference often challenging. Contactless heart rate—a technology-enabled biomarker of stress—was measured and broadcast on TV during the 2020 Tokyo Olympics archery first time in sports. Here we examined whether rate 122 adult archers predicted their this unique setting. We found higher rate—which...
Abstract We examine path dependency in physician decisions an emergency department setting, and find that physicians’ treatment for the current previous patients are positively correlated. show positive autocorrelation is higher when patient of greater medical uncertainty or more similar to terms observed characteristics less experienced fatigued. then these patterns highly consistent with memory attention model, whereby physician’s decision anchored her decision. The results from both...
