Researching Preferences,Valuation and Hypothetical Bias

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.      

浅谈建设项目招投标无标底报价的投标机制选择

无标底的投标机制有利于形成有效的市场竞争环境,能鼓励各建筑承包企业提高管理水平、降低生产成本、提高生产水平.应用信息经济学中的信息不对称理论分析了建设项目招投标过程中的信息不对称,并在此基础上建立了基于委托代理关系的建设项目招投标模型,并探索较合理的投标机制.     

经评审的最低投标价法的实践

随着中国建筑业管理体制改革的不断深化，招投标制度在中国得以推广应用，但目前以标底为中心的评标方法存在不足，有待完善。合理低价中标，具备不低于成本价、在合理的范围内两个条件，它代表着市场竞争的发展要求和方向，能够有效地减少一些人为因素。推进合理低价中标，应该把好资格审查关、标书评审关、招投标监督关，并要实行担保制，引入索赔机制。     

土地供应方式转变对房价的影响

中国城市土地供应方式经历了由无偿划拨到有偿出让,从协议出让到招拍挂出让的转变历程,当前招拍挂已经成为经营性用地的唯一出让方式。在地方政府"土地财政"的利益驱动下,土地单一垄断供应体制下的"招拍挂"土地出让方式已经成为影响房价上涨的重要因素之一。要遏制房价过快上涨的势头,应从根源上切断地方政府在房地产市场中的利益链条。     

论基于博弈论的投标报价建模方法

随着我国经济建设的发展,建筑市场的规范、有序化管理已经逐步形成,其中招投标制度在工程承发包交易行为公开、公平、提高工程质量、发挥投资效益、防止腐败和不正当竞争等方面均起到了很好的促进作用。根据现行的主要招投标评标方法,分析基于博弈论建立与之相适应的投标博弈模型的方法,为施工企业投标的科学决策提供借鉴。     

A strategic approach to improve sustainability in transportation service procurement

This paper focuses on the procurement of full truck-load transportation service with the view to ensuring sustainability in transport logistics. The carrier assignment problem (CAP) involved in truck load contract auction is studied using a complete enumeration method and heuristic approach. Performance of both methods is compared in terms of solution quality and computational time based on the results of sample problems considered. Also, the impact of combinatorial bidding on reducing empty haul in real world case is analyzed and environmental sustainability is achieved through reduction in carbon foot print.
