在大多数情况下，过早宣布未来的产品不可能是反竞争的。然而，当存在网络效应时，公司可能会有动机战略性地预先宣布产品;这种预先宣布通常被称为“雾件”。“反竞争的蒸汽软件指控已经针对IBM和微软。尽管反垄断关注的雾件，有没有实证工作在这个问题上。在这篇论文中，我们实证检验了DVD市场中的网络效应和雾件效应。我们发现DVD市场存在网络效应，DIVX的预告确实减缓了DVD技术的采用。
In most cases, the premature announcement of a future product cannot be anti-competitive. When there are network effects, however, firms may have incentives to strategically prenannounce products; such preannouncements are often referred to as "vaporware." Anticompetitive vaporware allegations have been leveled at IBM and Microsoft. Despite the antitrust concern about vaporware, there is no empirical work on the issue. In this paper, we empirically test for network effects and vaporware effects in the DVD market. We find that there are network effects in the DVD market and that the preannouncement by DIVX indeed slowed down the adoption of DVD technology.
