We study the efficiency properties of oligopoly equilibria in congested networks. Our measure of efficiency is the difference between users' willingness to pay and delay costs. Previous work has demonstrated that in networks consisting of parallel links, efficiency losses from competition are...

Besides their role in reducing frictions and facilitating trade, two-sided platforms increasingly collect and process data, e.g., supply and demand forecasts, that can further affect market outcomes. This paper studies how a platform may choose to disclose its information about future demand to...
