How AI Agents Follow the Herd of AI? Network Effects, History, and Machine Optimism
Unpacking AI Agent Behavior in Network-Effect Driven Environments
This study delves into how LLM-based AI agents navigate network-effect games, where individual payoffs hinge on peer participation. We reveal that agents struggle to infer equilibrium without structured historical data and exhibit persistent "AI optimism," highlighting history's crucial role in shaping machine reasoning—a paradigm shift for AI-mediated systems.

Insights from Static Game Analysis
Without historical data, LLM agents in static network-effect games exhibit significant dispersion in expectations, failing to converge to theoretical equilibrium. This highlights their inability to internalize the causal link between price and participation, demonstrating a lack of inherent recursive reasoning even in state-of-the-art models.
Stark Divergence
from theoretical equilibrium in static settings without history. AI agents show significant dispersion and disconnect from theoretical predictions, failing to internalize price-participation links.
Workflow Design for Dynamic Learning
The study introduces a novel workflow where LLM agents learn iteratively from historical data (price-participation trajectories). This design, aligned with in-context learning, allows agents to refine expectations, and critically, tests how algorithmic reinterpretation of past data shapes strategic outcomes.

Fixed Price Game Dynamics
In repeated games with fixed prices, weak network effects enable gradual convergence towards theoretical participation. However, under strong network effects, agents exhibit persistent "AI optimism," overestimating participation and failing to converge to equilibrium despite contradictory historical evidence. Strong network benefits override rational inference.
| Feature | Weak Network Effects (β=0.25) | Strong Network Effects (β=0.75) |
|---|---|---|
| Convergence | Gradual convergence towards theoretical N | Failure to converge; persistent 'AI optimism' |
| Historical Data Impact | Enables inference and alignment | Overridden by perceived collective gains |
| Key Outcome | Expectations align with FEE over rounds | Expectations remain inflated above actual N |
Analysis of Sequential Pricing Effects
Under ascending prices, LLMs can infer price effects and align with theoretical trends in weak network effects, but 'AI optimism' persists under strong effects. With decreasing prices, convergence improves significantly as prices drop, especially aligning with theory at lowest costs, but this alignment might be coincidental due to 'AI optimism' meeting favorable structural incentives rather than true rational learning.
Impact of Price Trajectories
In ascending price scenarios, LLM agents, despite initial deficits, learn to infer price effects under weak network conditions. However, strong network effects continue to fuel "AI optimism," causing agents to overestimate participation even at high prices, overriding rational signals. Conversely, under decreasing prices, agents show improved convergence as costs fall, aligning with theoretical predictions. Yet, this alignment may not signal true rational understanding but rather a 'sweet spot' where inherent AI optimism accidentally aligns with favorable structural incentives (low price, high beta), complicating interpretation of their strategic reasoning.
The Critical Role of History Structure
The study reveals that the ordering of history is critical. Randomized price trajectories entirely disrupt convergence, preventing agents from learning causal relationships between cost and participation. This demonstrates that LLMs' learning capacity is highly dependent on temporal coherence in data, a constraint unlike human reasoning which can infer causality amidst noise.
Temporal Coherence
is critical for LLM learning, unlike humans. Randomized price histories entirely disrupt agents' ability to generalize patterns, highlighting a fundamental difference in how LLMs process and infer causality from historical data compared to humans.

Your Path to Smarter AI Agent Systems
Implementing AI agent systems that truly learn from history requires a strategic approach. Here’s a typical roadmap:
Data Infrastructure & Agent Design
Establish the multi-agent simulation environment, configure LLM agents (e.g., Qwen family) with game rules and utility functions, and validate their initial comprehension. Focus on robust data pipelines for historical information.
Historical Data Simulation & Trajectory Testing
Implement various price trajectories (fixed, ascending, descending, random) and network-effect strengths. Run repeated decision-making scenarios and meticulously collect agent expectations and participation data.
Behavioral Analysis & Equilibrium Modeling
Analyze LLM agent behavior, comparing observed outcomes against theoretical fulfilled expectation equilibria. Identify and quantify biases like "AI optimism" and assess the critical impact of history's structure on their reasoning.
