Agent-Based Modeling

Routing Summary

This topic covers agent-based modeling theory, consumer behavior models, social dynamics, calibration/validation methods, and applications. Contains 5 sub-topics and 34 total concept notes derived from 4 papers.

• For ABM theory (definitions, emergence, heterogeneity, decision rules) → Foundations
• For consumer ABM models (Karakaya utility model, CUBES behavioral model) → Consumer Behavior
• For social interaction mechanisms (WOM, networks, diffusion, market dynamics) → Social Dynamics
• For calibration and validation (GA, HM+ABC, uncertainty quantification, case studies) → Calibration and Validation
• For ABM application domains (marketing, flows, finance, organizations, risk) → Applications
• For LLM-powered agents (generative agents, silicon samples / simulated respondents, homo silicus, validity and calibration of LLM populations) → LLM-Powered Agents

Sub-topics

• Foundations — COVERS: ABM methodology and principles, emergent phenomena, heterogeneity, ABM vs equation-based modeling, agent decision rules and bounded rationality
• Consumer Behavior — COVERS: Karakaya 4-component utility model, logit purchase decisions, CUBES behavioral attitudes (mistrust, opportunism, conditioning, innovativeness, imitation), behavioral primitives with threshold activation
• Social Dynamics — COVERS: WOM mechanisms (positive/negative), opinion leaders (exogenous vs emergent), social network formation, product adoption/diffusion models, network topology effects, market share equilibrium and lock-in
• Calibration and Validation — COVERS: ABM calibration overview (3 approaches), GA calibration (chromosome encoding, GA operators, convergence), RAM fitness evaluation (macro/micro), HM+ABC framework (implausibility score, wave-based pruning, rejection sampling ABC), uncertainty quantification (model discrepancy $V_m^r$, ensemble variance $V_s^r$, observation uncertainty $V_o$), case studies (SugarScape, territorial birds vs GA/SA/EA, RISC Scottish farms POM), experimental design (LHS, parameter sensitivity), validation (plausibility standard)
• Applications — COVERS: marketing strategy (4Ps under WOM), flow simulation (evacuation, traffic), financial market simulation, organizational simulation, operational risk modeling
• LLM-Powered Agents — COVERS: the LLM-agent paradigm for ABM (Gao et al. 2023 survey), generative-agent architecture with memory/reflection/planning (Park et al. 2023), silicon samples and algorithmic fidelity (Argyle et al. 2022), homo silicus economic experiments (Horton 2023), persona-mixture calibration, LLM vs rule-based agents, opinion-alignment metrics (Santurkar et al. 2023), and a validity/bias threat taxonomy with a validation protocol (8 notes, added 2026-09-18)
