Often, a single production process gives rise to a mass distribution of quality levels. If prices vary with quality, then input use is determined by interactions between the production‐quality‐input use relationship and the price‐quality relationship. Using dominance methods, I investigate how price‐quality schedules affect optimal input choices. Integral and differential conditions on changes in schedules are found that, together with conditions on the quality‐conditioned technology, are sufficient to determine changes in the intensity of input use.
