Handbook of computational economics : volume 2 Agent based computational economics The explosive growth in computational power over the past several decades offers new tools and opportunities for economists. This handbook volume surveys recent research on Agent based Computational Economics (ACE) the computational study of economic processes modeled as dynamic systems of interacting agents. Empirical referents for agents in ACE models can range from individuals or social groups with learning capabilities to physical world features with no cognitive function. Topics covered include: learning; empirical validation; network economics; social dynamics; financial markets; innovation and technological change; organizations; market design; automated markets and trading agents; political economy; social ecological systems; computational laboratory development; and general methodological issues. *Every volume contains contributions from leading researchers *Each Handbook presents an accurate self contained survey of a particular topic *The series provides comprehensive and accessible surveys
