 abstract = {This paper studies weekly output fluctuations from 1972 to 1983 at fifty final assembly plants in the U.S. automobile industry. The study makes use of a new data set that contains detailed information on plant operations. The main findings of the paper are: (1) Even at the simplest fabrication and assembly plant, there are a variety of margins on which production quantities are adjusted; (2) The production adjustment margins appear to have very different dynamic characteristics; and (3) The analysis of plant level data can lead to conclusions that are dramatically different from those reached using aggregated data, even though the data are driven by industry-wide shocks.},
