Stabilization policies frequently aim to boost spending as a means to increase GDP. Spending does not necessarily translate into production, however, especially when inventories are involved. We look at the cash-for-clunkers program that helped finance the purchase of nearly 700,000 vehicles in 2009. An analysis of auto sales and production movements reveals that the program did prompt a large spike in sales. But the program had only a modest and fleeting impact on production, as inventories buffered the movements in sales. These findings suggest caution in judging the efficacy of such policies by their impact on spending alone.
