Service Providers (SPs) however also have an interest in the deployment of such services. We hence propose a coinvestment scheme in which all stakeholders, i.e., the InP and the SPs, form the so-called grand coalition composed of all the stakeholders with the aim of sharing costs and revenues and maximizing their payoffs. The challenge comes from the fact that future revenues are uncertain. We devise in this case a novel stochastic coalitional game formulation which builds upon robust game theory and derive a lower bound on the probability of the stability of the grand coalition, wherein no player can be better off outside of it. In the presence of highly dependent fluctuations of revenues however, stability can be too conservative. In this case, we make use also of profitability, in which payoffs of players are non-negative, as a necessary condition for co-investment, and we derive a lower bound on the probability that co-investment is profitable. The proposed framework is showcased for MEC deployment, where computational resources need to be deployed in nodes at the edge of a telecommunication network. Numerical results show high lower bound on the probability of stability when the SPs’ revenues are of similar magnitude, even with high levels of uncertainty. In the case where revenues are highly variable however, the lower bound on stability can be trivially low whereas co-investment is still profitable.  \n1  \nKeywords: Co-investment, Uncertainty, Coalitional game, Stability, Profitability,  \nMobile Edge Computing  \n1 Introduction  \nSeveral examples exist of technologies that, from a purely technical point of view, would be ready to emerge or scale up, but whose development is hindered by a big economic barrier. This is the case of technologies requiring the deployment of a massive infrastructure, for which massive investments need to be engaged upfront, and whose precise future profits remain uncertain. We call Infrastructure Provider (InP) the actor responsible for deploying, maintaining and operating the physical infrastructure. We consider that, on top of such an infrastructure, third-party Service Providers (SPs) run their applications and collect revenues from end users.  \nAn example of this setting is the electric vehicle charging infrastructure (Badia et al. 2019), where the electric grid operator, acting as the InP, is tasked with deploying the grid infrastructure, e.g., bringing high-capacity electricity lines to road networks. On top of such grid infrastructure, electric vehicle charging station providers, which take the role of SPs, can operate their business and get revenues from end-users (drivers) (Fredriksson et al. 2019) .  \nAnother example, which is also the one we consider in the numerical results, involves the deployment and operation of Mobile Edge Computing (MEC) (Satyanarayanan 2017) . MEC is a computing architecture that decentralizes data processing by bringing it to the edge of the network, e.g., base stations (Shi et al. 2016) . This proximity to end-users reduces latency, improves bandwidth efficie","cbCaioeC9zaDEfrY","https://ap.wps.com/l/cbCaioeC9zaDEfrY","pdf",787148,2,1,62,"English","en",105,"# Abstract\n# Keywords\n#
