Intermediated Platforms and Firm Investments

Numerous studies have shown that cross-subsidization is a valuable tool to coordinate prices on each side of a platform, thereby increasing platform profits. We study how firm investments can be coordinated in an intermediated platform setting (where firms operating on a platform intermediate the relationship between the platform and end customers). In our setting, demand generated by a firm depends on own investments and prices, as well as cross-side investments and prices. We model this coordination problem using the case of Demand Response (DR) on the Smart Grid, where the platform enables interoperability between DR products, firms invest to develop DR products, and customers purchase DR products from firms. In the first stage the platform sets fees and transfers, and in the second and third stages, firms set prices and investments, respectively. We find that the platform’s choice of transfer maximizes aggregate platform demand - here, the platform and the policymaker are aligned. Although fees increase prices set by firms, thereby decreasing aggregate platform demand, the rate of price increase with fees depends on the demand facing each firm. We isolate conditions on firm demand where prices increase faster than fees (a phenomenon we term N-Convexity). Further, if there is N-Convexity, then it is inevitable that firm investment increases with fees (N-Investment); however, N-Investments can occur even when there is not N-Convexity.
