基于主体风险态度变更的拍卖机制优劣比较

On Comparison of the Auction Mechanism's Advantages and Disadvantages Based on the Different Attitudes of Bidders toward Risks

本文对拍卖"基准模型"中的招投标主体的风险态度假定进行了更符合实际的拓展,分别在招投标主体风险中性、风险偏好及风险厌恶的条件下对招标商收益进行了比较,得出了异于"收入等价定理"的若干结果,给招标商提供了选择招标机制的更进一步的方法。

This paper develops more practically the hypothesis of bidder's attitudes toward risks based on the 'Benchmark Model'. Then it further compares the different revenues under the conditions of the attitudes toward risk of the bidders, either risk neutral, risk loving or risk averse. Consequently, what is concluded in this paper is quite different from those obtained from 'Revenue Equivalence Theorem' and presents a more favorable method for the auctioneer to choose auction mechanism.
