A wide range of motives for holding inventories has been identified in the literature. These include the desire to smooth production in the face of fluctuating demand, the desire to avoid stockouts, and the desire to shift production into periods when costs are relatively low. Most of the...

Why did the volatility of U.S. real GDP decline by more than the volatility of final sales with the Great Moderation in the mid-1980s? One possible explanation is that firms shifted their inventory behavior towards a greater emphasis on production smoothing. We investigate the role of...

Empirically, sales are I(1). Starting from this fact, we derive three startling results. First, the variance of production is equal to the variance of sales in the long run. Second, this result holds regardless of the strength of production smoothing, stockout avoidance, or cost shocks. Third,...

Monthly data in physical units for seven industries are used to examine the production smoothing hypothesis. The results strongly support this hypothesis. Significant effects of expected future sales on current production are found for four industries, and the estimated decision equations for...
