摘要:

探讨了买家类型及卖家声誉存在差异时,网上交易平台收费及搜寻成本对价格离散程度的影响.结果表明:搜寻成本并不是导致网上交易市场价格离散性的根本原因;网上交易平台收费将导致两类买家的搜寻活动减少,且其降幅相同;网上交易平台对卖家收取的陈列费及其交易金额提成呈现出反方向变化的特征;当网上交易平台仅对卖家收费时,两类卖家均提高定价,但其提价幅度不同,从而使得网上交易市场中的价格离散程度降低;当网上交易平台对卖家和买家同时收费的时候,高声誉卖家的定价降低,低声誉卖家的定价提高,市场均衡时的价格离散性进一步降低乃至消失.

Abstract:

 For the existence of different buyers and sellers, the paper explores the effects of platform charges on equilibrium price and price dispersion. The results show that searching cost is not the basic reason for price dispersion. The decrease range of searching activities in different buyers that result from platform charges is equal. In addition, all sellers will raise their prices when the platform charges them, but the increase range in two groups is not equal,  it leads to reducing price dispersion degree. When platform charges both sellers and buyers, sellers with the higher reputation will reduce the price of products and sellers with lower reputation will raise the price, and finally the price dispersion degree reduce or even disappear.

Key words: platform charges, reputation, searching cost, price dispersion
