国际漫游资费逆向选择问题研究

A study of adverse selection of international roaming tariffs

针对当前国际漫游资费居高不下的情况,本文从国际漫游资费的结构出发,采用伯川德模型,提出国际漫游资费居高的原因是由于国际漫游批发价格不能反映被访运营商的市场需求,从而导致各运营商的机会主义行为。最后,提出如何消除这种信息不对称才能使国际漫游资费有效地降低。

First, the paper analyses the structural conditions of international roaming markets and then points out the cause why international roaming charges have remained high is that the wholesale price can not reflect the market demand of international roaming, thus inducing the operators' opportunism behavior. Finally, the paper puts forward some measures to eliminate information asymmetry so as to reduce international roaming tariffs efficiently.
