Declining Volatility in the U.S. Automobile Industry

American Economic Review,
Dramatic changes in the volatility of output occurred in the U.S. auto industry in the early 1980s. Namely, output volatility declined, the covariance of inventory investment and sales grew more negative, and adjustments to production schedules, which in earlier decades stemmed primarily from plants hiring and laying off workers, were more often accomplished with changes in average hours per worker after the mid- 1980s. Using a linear quadratic inventory model with intensive and extensive labor adjustments, we show how all of these changes could have stemmed from one underlying factor?a decline in the persistence of motor vehicle sales.
