The Learning Curve and Pricing in the Chemical Processing Industries
基于37种化学产品的数据，检验学习曲线与工业定价的假设，发现学习效应显著且与累计产出和投资相关，市场集中度影响价格灵活性。
Data on 37 chemical products are used to test a number of hypotheses about the learning curve and industrial price behavior. The results document a strong and consistent learning effect. Learning is found to be a function of cumulated industry output and cumulated investment rather than calendar time. Standard economies of scale appear significant but small in magnitude relative to the learning effect. Variations in the slope of the learning curve are linked to differences in R&D expenditures and capital intensity. Market concentration is found to be a strong influence on price flexibility and the timing of learningrelated price changes.
