通过构造财富效用函数建立了产权协商交易定价模型,导出产权交易定价的加权边际效用零和方程.根据不同竞买人的偏好差异和对产权的预期价值差异,运用出售方与不同竞买人的加权边际效用零和的定价方程求解出对应的协商交易均衡价格,并选择最大均衡价格作为产权拍卖中标的参考价格.计算了不同中标价格的出售方和中标人的财富效用值和福利水平值,比较发现只有以最大均衡价格中标产权拍卖的福利水平和市场效率最高;若中标价格大于产权的最大预期价值,拍卖交易的福利水平为负,并出现所谓的“赢者灾难”.对竞买人用于竞标的财富实力对均衡价格的影响作了初步探讨,其研究结论符合常理.
通過構造財富效用函數建立瞭產權協商交易定價模型,導齣產權交易定價的加權邊際效用零和方程.根據不同競買人的偏好差異和對產權的預期價值差異,運用齣售方與不同競買人的加權邊際效用零和的定價方程求解齣對應的協商交易均衡價格,併選擇最大均衡價格作為產權拍賣中標的參攷價格.計算瞭不同中標價格的齣售方和中標人的財富效用值和福利水平值,比較髮現隻有以最大均衡價格中標產權拍賣的福利水平和市場效率最高;若中標價格大于產權的最大預期價值,拍賣交易的福利水平為負,併齣現所謂的“贏者災難”.對競買人用于競標的財富實力對均衡價格的影響作瞭初步探討,其研究結論符閤常理.

The bargaining pricing model is built by constructing the wealth utility function of property right price; the equation of weighted marginal utility zero-sum for solving the equilibrium price of property right is derived. In the light of differenc.es of preferences and expectation values to property right of buyers, the equilibrium prices of bargaining is solved by means of the different equations of weighted marginal utility zero-sum of seller and buyers with a numerical case, and the maximum equilibrium price is chosen as the winner reference price. The wealth utilities and welfare function level of the seller and the winners at different winner prices are computed, by the comparison of the computed results, only the maximum equilibrium price has the highest welfare function level and highest market efficiency. And if the winner price is higher than the maximum expected value of the property right, the welfare function level is negative, it is so called "Winner's curse". At last, the effect of wealth power of a buyer for target property right on equilibrium price is initially discussed, which result conforms to common rule.
