We provide evidence that industries' supply curves are convex. To guide our empirical analysis, we develop a model, in which capacity constraints at the plant level generate convex supply curves at the industry level. The industry's capacity utilization rate is a sufficient statistic for the...

We provide evidence that industries' supply curves are convex. To guide our empirical analysis, we develop a putty-clay model in which capacity constraints at the plant level generate convex supply curves at the industry level. The model's key insight is that an industry's capacity utilization...
