The Interplay of Competition and Cooperation Among Service Providers

摘要:

我们认为,移动虚拟网络运营商(MVNO)和移动网络运营商(MNO)之间的相互作用的经济。我们调查的MNO提供她的一些资源的MVNO,而不是使用她自己的最终用户(EU)的资源的动机。我们考虑一个市场,一个MNO和一个MVNO,和一个连续的未定EU。考虑EU的两种情况:(i)EU需要选择MNO或MVNO时,以及(ii)EU具有外部选项时。在每一种情况下,我们考虑一个非合作框架的序贯博弈和合作框架的讨价还价博弈。我们刻画了序贯博弈和讨价还价博弈的子博弈完美纳什均衡(SPNE)和纳什谈判解(NBS)。我们表明,在非合作的框架,SPNE采取两种形式:(一)MNO投资最低限度地对她的基础设施和MVNO租赁所有新投资的资源和(ii)MNO投资更多的基础设施,MVNO租赁这些资源的MVNO只有一部分,和MNO使用自己的休息,以吸引欧盟。因此,在这两种情况下,MNO通过MVNO间接产生收入。除此之外,在(ii)中,MNO直接从EU产生收入。我们还证明了在谈判框架中,MVNO要么保留所有资源,要么不从MNO的资源,和MNO的投资是由欧盟是否有一个外部选项。如果他们不这样做,那么MNO就尽可能少地投资于她的基础设施。如果他们这样做,那么MNO投资更多。

英文摘要:

We consider the economics of the interaction between Mobile Virtual Network Operators (MVNOs) and Mobile Network Operators (MNOs). We investigate the incentives of an MNO for offering some of her resources to an MVNO instead of using the resources for her own End-Users (EUs). We consider a market with one MNO and one MVNO, and a continuum of undecided EUs. Two cases for EUs are considered: (i) when EUs need to choose either the MNO or the MVNO, and (ii) when EUs have an outside option. In each of these cases, we consider a non-cooperative framework of sequential game and a cooperative framework of bargaining game. We characterize the Subgame Perfect Nash Equilibria (SPNE) and Nash Bargaining Solution (NBS) of the sequential and bargaining games, respectively. We show that in the non-cooperative framework, SPNE assumes two forms: (i) the MNO invests minimally on her infrastructure and the MVNO leases all the newly invested resources and (ii) the MNO invests more on her infrastructure, the MVNO leases only part of these resources to the MVNO, and the MNO uses the rest herself to attract EUs. Thus, in both, the MNO generates revenue indirectly through the MVNO. In addition to that, in (ii), the MNO generates revenue directly from the EUs. We also prove that in the bargaining framework, the MVNO either reserves all the resources or no resources from the MNO, and the MNO's investments are guided by whether EUs have an outside option. If they don't, then the MNO invests as little as possible on her infrastructure. If they do, then the MNO invests more.
