Introduction Decentralized market economies
– Complex adaptive systems of large number of adaptive agents involved in parallel local interactions
– Dynamic system of recurrent causal chains connecting individual behaviors, interaction networks, and social welfare outcomes
• Macroeconomic regularities: shared market protocols, behavioral norm feed back to local interactions
Traditional quantitative economic models
– Top-down construction of microfoundations
– Fixed decision rules, common knowledge assumptions, representative agents, imposed market equilibrium constrains
New quantitative models
– Inductive learning, imperfect competition, endogenous trade network formation, open-ended co-evolution of individual behaviors and economic institutions

Introduction (2)
Agent-based computational economics (ACE)
– Computational laboratories under controlled experimental conditions
• Descriptive and normative
– Initial population of agents: economic agents (traders, financial institutions, …), agents representing various other social and environmental phenomena (government, land, weather, …)
– Historical time-line of agent-agent interactions
Artificial life
– Demonstrate constructively how global regularities might arise from the bottom up, through the repeated local interactions of autonomous agents
– Model in ACE: representations of existing or potential economic processes

Open Issues and Future Research
Learning and the embodied mind
– How to model minds of computational agents who populate ACE frameworks
Evolution of behavioral norms
– How mutual cooperation manages to evolve among economic agents even when cheating reaps immediate gains and binding commitments are not possible
Bottom-up modeling of market processes
– How to explain the evolution of markets and other market-related economic institutions
Formation of economic networks
– Manner where economic interaction networks are determined through deliberative choice of partners as well as by chance
