LLM agents autonomously generate context-based decisions, exhibiting human-like behavior and strong capabilities in individual simulations like economic experiments.
Large Language Model (LLM) agents can autonomously generate decisions based on specific contexts, making their behavior more human-like and demonstrating strong individual simulation capabilities. In economic experiments, LLM agents endowed with specific personalities exhibit behavior patterns consistent with classical theory, such as downward-sloping demand curves and diminishing marginal utility. They have also shown rational behavior in budget allocation tasks, sometimes exceeding human performance in resource trade-off decisions. Studies confirm that LLMs can replicate results from human participant experiments in games like the ultimatum game, public goods game, and prisoner’s dilemma, passing the Turing test in these settings. Furthermore, LLMs trained on vast human-generated text corpora have learned implicit models of human reasoning and decision-making, enabling them to serve as proxies for human subjects in economic modeling. For instance, LLM agents have demonstrated tendencies toward fairness and status quo bias, aligning with known human behavioral patterns. However, their ability to exhibit human-like economic behavior often depends on prompt design that incorporates social context, as unguided LLMs may produce overly rational outputs not reflective of actual human choices
This research investigates the integration of Large Language Models (LLMs) as autonomous agents within socio-economic frameworks, moving beyond static rule-based systems to dynamic, context-aware decision-making. The material covers the architectural and behavioral aspects of deploying these agents in individual simulations, specifically focusing on how they interpret environmental cues and generate autonomous decisions. It provides a detailed analysis of agent interactions in controlled settings, demonstrating that LLMs can effectively navigate complex scenarios requiring adaptive reasoning similar to human participants.
A key contribution of this work is the empirical evidence that LLM agents exhibit behavior strikingly similar to human subjects in controlled economic experiments. The study highlights the agents' capacity to model economic rationality and social norms, mirroring human-like responses in game-theoretic setups without explicit task-specific fine-tuning. This suggests that LLMs possess an intrinsic ability to infer strategic incentives and social context, allowing them to replicate the nuances of human economic behavior with high fidelity.
The significance of this research lies in its potential to revolutionize computational social science and economic modeling. By providing a scalable, controllable proxy for human subjects, these AI agents enable researchers to conduct high-throughput simulations and stress-test economic theories with a speed and variety that traditional human-subject studies cannot match. This approach offers a powerful new sandbox for validating socio-economic models, exploring emergent behaviors in complex systems, and potentially informing policy decisions through predictive agent-based modeling.

This paper introduces a socio-economic model for Large Language Model (LLM) agents, demonstrating their ability to autonomously generate context-based decisions that mimic human-like behavior. The authors focus on individual simulations, particularly economic experiments, where LLM agents exhibit strong performance in tasks requiring adaptive reasoning, strategic interaction, and decision-making under uncertainty. The model explores how these agents can navigate dynamic environments, such as market interactions, bargaining scenarios, or resource allocation problems, by leveraging their language understanding and generative capabilities.
The key contributions include: 1. Autonomous Decision-Making: The paper validates that LLM agents can operate independently in structured socio-economic simulations, producing behavior consistent with human participants in experimental economics. 2. Contextual Adaptability: The agents dynamically adjust their strategies based on evolving conditions, showcasing robustness in multi-agent settings where outcomes depend on others' actions. 3. Scalability & Generalization: The model highlights the potential for LLMs to serve as scalable, low-cost alternatives for economic modeling, agent-based simulations, and behavioral research.
Why it matters: This work bridges AI and social sciences by providing a framework for studying emergent phenomena in artificial agent economies. It has implications for fields like autonomous systems, behavioral economics, and policy modeling, where synthetic agents could replace or augment human subjects in large-scale experiments. Additionally, it raises questions about the ethical and practical boundaries of AI-driven decision-making in real-world socio-economic systems.
