Information sharing and competition in the motor vehicle industry
Doyle, Maura P.; Snyder, Christopher M. (1997)
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.

The evidence of an overshifting of prices offers support for the recent models of tax incidence in imperfectly competitive markets. The results also suggest that changes in the after-tax interest rate have offsetting effects on new car prices; a one percentage point increase in the after-tax real interest rate will prompt, on average, a mark-down of $106.
