摘要：Firms often announce new products well in advance of their actual market availability.
The incentives for pre-announcements are conceived to be stronger in markets with network
effects because they can be used to induce the delay of consumersʼ purchases and forestall the
build-up of rival productsʼ installed bases. However, such announcements often are not fulfilled,
raising antitrust concerns. We analyze the effects of product pre-announcements in the presence
of network effects when firms strategically make false announcements. We also discuss their
implications for consumer welfare.
