This paper shows that, in several U.S. manufacturing industries, the seasonal variability of production and inventories varied with the state of the business cycle. The authors present a simple model which implies that, if firms reduce the seasonal variability of their production as the economy strengthens and they either hold constant or increase the stock of inventories they bring into the high-production seasons of the year, then they must be facing upward-sloping and convex marginal cost curves. The authors conclude that firms in a number of industries face upward-sloping and convex marginal-production-cost curves. Copyright 1997 by American Economic Association.
