我们对四种头孢菌素的需求进行建模，并计算这四种药物的品牌和仿制药之间的自有和交叉价格弹性。我们的模型需求作为一个多阶段的预算问题，我们认为，这样的模型是适当的多阶段性质的购买药品，特别是处方和配药阶段，我们发现相当高的弹性之间的通用替代品和一些治疗替代品之间的显着的弹性。
We model demand for four cephalosporins and compute own- and cross-price elasticities between branded and generic versions of the four drugs. We model demand as a multistage budgeting problem, and we argue that such a model is appropriate to the multistage nature of the purchase of pharmaceutical products, in particular the prescribing and dispensing stages, We find quite high elasticities between generic substitutes and also significant elasticities between some therapeutic substitutes.
