Two Paths in Economic-Agent Modeling

The parallel development of structural equilibrium modeling and agent-based computational economics.

TWO EVOLUTIONARY PATHSEconomic-Agent Decision Modeling and Solution Methods

Aggregate relations→DSGE→Heterogeneous-agent models→AI-assisted solution

Core: structural consistency across decisions, prices, and allocations.

Local interaction→Markets and finance→Macro ABMs→RL and LLM agents

Core: processes and aggregate outcomes emerging from heterogeneous interaction.

HOW TO READ

Key takeaways

01
The Lucas critique made endogenous behavioral responses to policy central to structural modeling.
02
Heterogeneous-agent models make distributions part of the aggregate state.
03
ACE emphasizes adaptation, interaction, and emergent aggregate processes.
04
AI expands both complex solution methods and agent behavior generation.
