Information Sharing and Competition in the Motor Vehicle Industry

  • Maura P. Doyle
  • Christopher M. Snyder

Up to six months ahead of actual production, U.S. automakers announce plans for their monthly domestic production of cars. A leading industry trade journal publishes the initial plan and then a series of revisions leading up to the month in question. We analyze a panel data set spanning the years 1965--1995, matching the production forecasts with data for actual monthly production. We show that a firm's plan announcement affects competitors' later revisions of their own plans and eventual production. The interaction appears to be complementary---large plans or upward revisions cause competitors to revise plans upward and increase production. The results are consistent with models in which firms share information about common demand parameters.
