  1. Turing Memorial Session at 4th WCSS, Taipei.


  2. Turing Memorial session is organised, by ASSRU, as a Special Session of the 4th World Congress of Social Simulation, to be held in Taipei, during September, 4-7, 2012. The session will pay homage to Alan Turing on his birth centennial and will focus on topics related to the research program on Turing's Economics.

    Topic: The Epistemology of Simulation, Computation and Dynamics in Economics

    Abstract

    We identify and characterise five frontier research fields, encompassing both micro and macro aspects of economic theory, where machine computation, in its digital mode, play crucial roles in formal modelling exercises: computable general equilibrium theory, agent based computational economics, computational economics, classical behavioural economics and computable economics. These five research frontiers broach, without resolving, many interesting methodological and epistemological issues in economic theorising in (alternative) mathematical modes. The main claim in the paper is that there is a serious epistemological deficit in the first three approaches, but none in the last two, precisely because the latter are underpinned by computability and constructivity theories, in their strict mathematical senses, and the former are not. However, this claim does not imply that classical behavioural economics and computable economics are 'complete' from an epistemological perspective, especially from the point of view of natural or intrinsic dynamics of formal models. The epistemological deficit in the one case, and the epistemological incompleteness in the second alternative, it is suggested, can be resolved by a theory of simulation, itself based on recognising the 'duality' between dynamical systems and numerical analysis, interpreted computably. Hence paying heed to Turing's Precept: ''the inadequacy of 'reason' unsupported by common sense.''
