价格刚性条件下多项式时间内不可分割资源的分配

Allocating Indivisible Resources under Price Rigidities in Polynomial Time

Wei Huang, Jian Lou, Zhonghua Wen

摘要:

在许多现实的资源配置问题中,经济效率必须与社会公平相结合,价格刚性往往是根据一定的经济和社会需要而制定的。研究了价格刚性条件下销售多个不可分割商品的动态机制的计算问题。我们提出了一个多项式算法,可以用来找到过度需求的项目集,然后引入一个动态的机制与配给发现价格刚性下的约束瓦尔拉斯均衡在多项式时间。我们还讨论了卖方期望利润和物品期望价格的计算,并讨论了期望利润意义下的战略问题。

英文摘要:

In many realistic problems of allocating resources, economy efficiency must be taken into consideration together with social equality, and price rigidities are often made according to some economic and social needs. We study the computational issues of dynamic mechanisms for selling multiple indivisible items under price rigidities. We propose a polynomial algorithm that can be used to find over-demanded sets of items, and then introduce a dynamic mechanism with rationing to discover constrained Walrasian equilibria under price rigidities in polynomial time. We also address the computation of sellers' expected profits and items' expected prices, and discuss strategical issues in the sense of expected profits.
