Paul Scott and coauthors develop a model of competition in prices and infrastructural investment among mobile network providers. Market shares and service quality (download speed) are simultaneously determined, for demand affects the network load just as delivered quality affects consumer demand. While consolidation typically has adverse impacts on consumer surplus, economies of scale push in the other direction. Consumer surplus is maximized at a moderate number of firms, and that the optimal number of firms is higher for lower income consumers.
