Barriers to network-specific investment

Abstract

We examine incentives for network-specific investment and consider the implications for network governance. We model a two-sided market in which participants making payments over a network platform can invest in a technology that reduces the marginal cost of using the platform. A network effect results in multiple equilibria -- either all agents invest and use of the platform is high or no agents invest and use of the platform is low. The high-use equilibrium can be implemented if commitment is feasible. When the platform cannot commit to usage fees, investment in the platform-specific technology will be held-up, thus implementing the low-investment equilibrium. As a result, governance structures necessary to achieve commitment will be preferred to those necessary merely to achieve coordination. For example, mutual ownership by users of a network platform may emerge where users face risk of ex-post renegotiation. Such a governance structure will also be sufficient to avoid low investment attributable to the network effect. (Copyright: Elsevier)
