Abstract: This paper provides a framework in which a multiproduct ecosystem competes with small single-product firms in both price and innovation. The ecosystem is able to use data collected on one product to improve the quality of its other products. We study the impact of regulation which either restricts the use of data across the ecosystem’s business units, or which requires the ecosystem to share data with small firms. This regulation induces small firms to innovate more and set higher prices; it also dampens data spillovers within the ecosystem, reduces the ecosystem’s incentive to innovate, and potentially increases its prices. As a result, the impact of data regulation on consumers is ambiguous. Small firms do not necessarily benefit from sharing data with each other via a data cooperative, because doing so triggers more aggressive pricing by the ecosystem. A data cooperative can also harm consumers by inducing the ecosystem to innovate less.
