John Hogan, "From Complexity to Perplexity" (html), Scientific American, Volume 272, June 1995, pages 74-79.

This controversial article is a rather cynical and caustic view of the research on complex systems undertaken at the Santa Fe Institute through the mid-1990s. At the very least, it provides a cautionary note to researchers regarding the dangers of over-hyping (by media commentators among others) of new and as-yet unproven methodologies related to the study of complex systems.

Blake LeBaron, "Agent Based Computational Finance: Suggested Readings and Early Research" (pdf preprint,153K), Journal of Economic Dynamics and Control, Volume 24, Numbers 5-7, 2000, pages 679-702.

Abstract: This paper explores some of the early work in finance making use of computer simulated markets with individual adaptive agents. Six papers are summarized in detail, and references are given to many other studies in this wide-ranging research area. It also addresses many of the questions that new researchers will face when getting into the field.

Scott E. Page, "Computational Models from A to Z" (html), Keynote Address to SwarmFest'99, The Anderson School of Management at the University of California at Los Angeles, March 27-29, 1999.

Author's Abstract: "The growing use of computational models of social, physical and biological systems raises many questions and concerns. Platforms such as Swarm enable researchers to construct detailed, robust computational models. The availability of Swarmlike platforms will speed the pace of the computational revolution and open new areas of research. In this brief tongue-in-cheek overview, I discuss twenty-six topics pertaining to these computational models. Unbelievably, each of the twenty-six subject headings begins with a different letter! Given this fortuitous fact, I have chosen to arrange the topics alphabeticaly. Though containing bits of levity, this paper should be read seriously both as a social scientist's commentary on a nascent field and as a guide to future research."

Judd (eds.), Handbook of Computational Economics, Volume 2: Agent-Based Computational Economics (Preface, Contributors, and Abstracts), Handbooks in Economics Series, North-Holland, Amsterdam, 2006, 904pp.

Abstract: This chapter explores the potential advantages and disadvantages of Agent-Based Computational Economics (ACE) for the study of economic systems. General points are concretely illustrated using an ACE model of a two-sector decentralized market economy. Six issues are highlighted: Constructive understanding of production, pricing, and trade processes; the essential primacy of survival; strategic rivalry and market power; behavioral uncertainty and learning; the role of conventions and organizations; and the complex interactions among structural attributes, behaviors, and institutional arrangements.

Abstract: This study is an extended version of the previous PNAS overview. The main objectives and defining characteristics of agent-based computational economics (ACE) are outlined, and similiarities and distinctions between ACE and artificial life research are clarified. Eight ACE research areas are identified, and a number of publications in each area are highlighted for concrete illustration. Open questions and directions for future ACE research are also considered. The study concludes with a discussion of the potential benefits of the ACE approach, as well as some potential difficulties.

Abstract: This study presents a summary overview of the basic artificial life (alife) paradigm, stressing aspects especially relevant for the study of decentralized market economies. In particular, recent work on a Trade Network Game (TNG) framework combining evolutionary game play with endogenous partner selection is used to illustrate how the alife paradigm might be specialized to economics. Analytical and simulation work is reported to show how the TNG is currently being used to study the evolutionary implications of alternative market structures at three different levels: individual trade behavior; trade network formation; and social welfare.

Author's Abstract: "In order to address the question whether F. A. Hayek might have been an Agent-Based Computational Economist (ACE) avant-la-lettre, an ACE model concerning the phenomenon of information contagion is considered. It is shown how information-contagious behavior can emerge in a coevolutionary process of interacting adaptive agents, how this is related to various Hayekian themes, and how ACE research in general is an application of Hayek's methodological insights."
