--- abstract: 'This article aims to test the relevance of learning through Genetic Algorithms (GA) and Learning Classifier Systems (LCS), in opposition with fixed R&D rules, in a simplified version of the evolutionary industry model of Nelson and Winter. These three R&D strategies are compared from the points of view of industry performance (welfare): the results of simulations clearly show that learning is a source of technological and social efficiency.' altloc: - http://147.210.86.202/ifrede/e3i/publications/WP/article.php3?SELECTWP=2001-1 chapter: ~ commentary: ~ commref: ~ confdates: ~ conference: ~ confloc: ~ contact_email: ~ creators_id: - yildi creators_name: - family: Yildizoglu given: Murat honourific: '' lineage: '' date: 2001 date_type: published datestamp: 2004-10-08 department: ~ dir: disk0/00/00/38/64 edit_lock_since: ~ edit_lock_until: ~ edit_lock_user: ~ editors_id: [] editors_name: [] eprint_status: archive eprintid: 3864 fileinfo: /style/images/fileicons/application_pdf.png;/3864/1/2001%2D1.pdf full_text_status: public importid: ~ institution: ~ isbn: ~ ispublished: ~ 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: ' Learning, Learning Classifier Systems, Bounded Rationality, Technical Progress, Innovation' lastmod: 2011-03-11 08:55:42 latitude: ~ longitude: ~ metadata_visibility: show note: 'JEL Classification: O3, L1, D83' number: ~ pagerange: ~ pubdom: FALSE publication: ~ publisher: ~ refereed: FALSE referencetext: |- Butz, M.
