The Sea Battle Tomorrow: The Identity of Reflexive Economic Agents

Chapter 7 in Keynesian, Sraffian, Computable and Dynamic Economics, 2021, pp 187-214 from Springer

Abstract: Abstract This chapter develops a conception of reflexive economic agents as an alternative to the standard utility conception and explains individual identity in terms of how agents adjust to change in a self-organizing way, an idea developed from Herbert Simon. It seeks to model the behavior of economic agents in a manner that builds on the important contributions of Stefano Zambelli to the understanding of computation and dynamical economic systems. This chapter distinguishes closed equilibrium and open process conceptions of the economy and argues the former fails to explain time in a before-and-after sense in connection with Aristotle’s sea battle problem. A causal model is developed to represent the process conception, and a structure-agency understanding of the adjustment behavior of reflexive economic agents is illustrated using Merton’s self-fulfilling prophecy analysis. Simon’s account of how adjustment behavior has stopping points is then shown to underlie how agents’ identities are disrupted and then self-organized, and the identity analysis this involves is applied to the different identity models of Merton, Ross, Arthur, and Kirman. Finally, the self-organization idea is linked to the recent ‘preference purification’ debate in bounded rationality theory regarding the ‘inner rational agent trapped in an outer psychological shell,’ and it is argued that the behavior of self-organizing agents involves them taking positions toward their own individual identities.
