--- abstract: 'The rational agency assumption limits systems to domains of application that have never been observed. Moreover, representing agents as being rational in the sense of maximising utility subject to some well specified constraints renders software systems virtually unscalable. These properties of the rational agency assumption are shown to be unnecessary in representations or analogies of markets. The demonstration starts with an analysis of how the rational agency assumption limits the applicability and scalability of the IBM information filetering economy. An unrestricted specification of the information filtering economy is developed from an analysis of the properties of markets as systems and the implementation of a model based on intelligent agents. This extended information filtering economy modelis used to test the analytical results on the scope for agents to act as intermediaries between human users and information sources.' altloc: - ftp://www.cpm.mmu.ac.uk/pub/papers/rat-agents.pdf chapter: ~ commentary: ~ commref: ~ confdates: ~ conference: ~ confloc: ~ contact_email: ~ creators_id: [] creators_name: - family: Moss given: Scott honourific: '' lineage: '' date: 1999-04 date_type: published datestamp: 1999-04-08 department: Centre for Policy Modelling dir: disk0/00/00/05/34 edit_lock_since: ~ edit_lock_until: ~ edit_lock_user: ~ editors_id: [] editors_name: [] eprint_status: archive eprintid: 534 fileinfo: /style/images/fileicons/application_pdf.png;/534/3/rat%2Dag2a.pdf full_text_status: public importid: ~ institution: Manchester Metropolitan University isbn: ~ ispublished: pub issn: ~ item_issues_comment: [] item_issues_count: 0 item_issues_description: [] item_issues_id: [] item_issues_reported_by: [] item_issues_resolved_by: [] item_issues_status: [] item_issues_timestamp: [] item_issues_type: [] keywords: 'rational agency, utility, rationality, agent-based models, information markets, market process, market structure, intermediaries, scalability, brokers, brokerage, economic rationality, rational economic man, bounded rationality, systems, applications, simulation, declarative language, SDML' lastmod: 2011-03-11 08:54:02 latitude: ~ longitude: ~ metadata_visibility: show note: ~ number: ~ pagerange: ~ pubdom: FALSE publication: ~ publisher: ~ refereed: FALSE referencetext: ~ relation_type: [] relation_uri: [] reportno: 'CPM Report No.: 99-51' rev_number: 12 series: ~ source: ~ status_changed: 2007-09-12 16:30:15 subjects: - comp-sci-art-intel - comp-sci-mach-dynam-sys - comp-sci-mach-learn - phil-sci - soc-psy succeeds: ~ suggestions: ~ sword_depositor: ~ sword_slug: ~ thesistype: ~ title: The Cost of Rational Agency type: techreport userid: 451 volume: ~
