Using data from one of Australia's largest thoroughbred auction houses, we investigate the price determinants of thoroughbred yearlings sold at auction. We include novel key variables to construct hedonic pricing models and examine the relative role of stud fees compared to the wide range of attributes in the pricing of yearlings. We find that the price effect of stud fees is influenced by the value buyers place on both the characteristics of sires and the characteristics of sire side siblings. The findings imply that the quality of dams a sire has been matched within the breeding market has consequential effects on yearling prices through the sire's stud fee and progeny.  相似文献

We characterize the equilibrium of the all-pay auction with general convex cost of effort and sequential effort choices. We consider a set of n players who are arbitrarily partitioned into a group of players who choose their efforts ‘early’ and a group of players who choose ‘late’. Only the player with the lowest cost of effort has a positive payoff in any equilibrium. This payoff depends on his own timing vis-a-vis the timing of others. We also show that the choice of timing can be endogenized, in which case the strongest player typically chooses ‘late’, whereas all other players are indifferent with respect to their choice of timing. In the most prominent equilibrium the player with the lowest cost of effort wins the auction at zero aggregate cost. We thank Dan Kovenock and Luis C. Corchón for discussion and helpful comments. The usual caveat applies. Wolfgang Leininger likes to express his gratitude to Wissenschaftszentrum Berlin (WZB) for its generous hospitality and financial support.  相似文献

二十多年来 ,中国政府一方面强调农户承包经营土地的长期稳定 ,一方面鼓励土地使用制度的不断创新 ,因而中国农地使用制度呈现出“两田制”、“规模规营”、‘四荒’使用权拍卖”、“股份合作制”等多种形态。而“土地调整”和“使用权流转”一直是中国农地制度变迁中的普遍现象。文章对上述中国农地使用制度变迁进行了实证性的分析。  相似文献

Physical Search     
Unidirectional search is an evolutionarily stable outcome in an economy where homogenous buyers and sellers can either move or stay. It is more efficient than bidirectional search. In unidirectional search, it is more efficient if the more numerous agents move and the less numerous agents stay, than vice versa.  相似文献

We show that all-pay auctions dominate first-price sealed-bid auctions when bidders face budget constraints. This ranking is explained by the fact that budget constraints bind less frequently in the all-pay auctions, which leads to more aggressive bidding in that format.  相似文献

Researching Preferences,Valuation and Hypothetical Bias   总被引:1,自引:0,他引:1  
A number of recent papers in environmental economics have focused on the process of researching preferences – agents are uncertain about preferences but with effort may narrow their uncertainty. This issue has arisen in formulating bids in contingent valuation (CV) as well as the debate over the divergence between WTP and WTA. In the context of CV, it has been suggested that the hypothetical nature of the preference elicitation process biases responses. This paper provides both a theoretical model and experimental evidence to contribute to this debate. The model is a model of competitive bidding for a private good with two components that are particularly relevant to the debate. The first component is that bidders are unsure of their own value for the private good but may purchase information about their own value (researching preferences). The second component is that there is a probability that the auction is hypothetical – that the winning bidder will not get the private good and will not pay the winning bid. The experiment tests this theoretical model of bidding equilibrium and analyzes the effects of variations in the parameters (hypotheticalness, information costs and number of agents) on the endogenous variables (such as the proportion of bidders who become informed and the winning bid). Experimental results suggest that an increase in the hypotheticalness of an auction tends to decrease the likelihood that bidders pay for information on their valuation with an ambiguous effect on the winning bid.   相似文献

产品的独特性、产品对企业的重要性、企业的采购量、供应市场状况、供应商的讨价还价能力和企业风险影响供应商关系管理策略。反向营销和反向拍卖是两种不同的供应商关系管理理念,不过全球经济一体化和技术的发展决定了企业中的多数产品既可以实行反向拍卖策略,也可以实行反向营销策略。从直接采购成本、直接交易成本、关系处理成本和供应处理成本四类供应商关系成本以及两类关系收益(成本收益和收入收益)的角度探讨了两种供应商关系管理模式的选择。  相似文献

This note uses the Theorem of the Alternative to prove new results on the implementability of general, asymmetric auctions, and to provide simpler proofs of known results for symmetric auctions. The tradeoff is that type spaces are taken to be finite.  相似文献

许多企业在采购时,常常将整笔业务拆分为两个合同:较大的第一合同和较小的第二合同,通过分批二级价格封闭式招标来选择不同的供应商供货。本文通过建立分批招标模型分析了供应商的投标策略和买方的采购策略,得出了当参加第一合同竞标的供应商数目和第二合同新引入的供应商数目满足一个不等式时,拆分招标的采购成本小于整体招标的采购成本,并且指出了拆分比例对拆分招标的采购成本的影响。  相似文献

电子采购招标拍卖与供应商管理   总被引:3,自引:0,他引:3  
周蓉 《物流技术》2002,(2):14-15,31
介绍了电子采购的工作流程,在此基础上研究了电子采购招标与拍卖的博弈论模型及其赢者灾难现象;论述了虽然电子采购提高了工作效率,采购方享受了招标与拍卖带来的节约,介是它不仅有可能疏远了采购方供应商之间的关系,而且使得讨价还价的权力将最终转移到供应商这一方。  相似文献
