Sole-Sourcing versus Competitive Bidding: US Government Agencies' Procedural Choices for Mainframe Computer Procurement
研究了美国政府机构在采购大型计算机时，为何有时选择独家采购、有时选择竞争性招标，发现供应商竞争程度、采购价值以及买方与供应商的合作经验等因素显著影响程序选择。
Why do government agencies sole-source sometimes and use competitive procedures for procurement other times? This paper develops a testable model of the economic determinants of agencies' procurement procedures and applies it to procurement of general-purpose mainframe computer systems. Factors related to the extent of vendor competition or the value of a procurement importantly influences an agency's procedural choice. Extensive experience between an agency buyer and an incumbent vendor, or the buyer's experience with IBM, also helps predict the agency's procedural choice. Copyright 1995 by Blackwell Publishing Ltd.
