报告内容摘要

Abstract: Product diffusions models, such as generalized Bass models, incorporate individual buying decisions represented by utility functions. However, product diffusion processes emerge naturally from individual decisions. In this talk, we derive product diffusion models from utility functions, and compare the resulting models with classical ones. We show that, for simple assumptions such as a single product with constant price, even though the product diffusion may not agree with generalized Bass models, the demand curve agrees with classical results. But with time varying prices and competing products, the demand curves do not agree with classical results. Thus, for optimal pricing of such product, the diffusion process cannot be neglected.
