Dynamic Modeling of the Product Life Cycle in the Commercial Mainframe Computer Market, 1968-1982

No 6124, NBER Working Papers from National Bureau of Economic Research, Inc

Abstract: This research investigates product life cycles in the commercial mainframe computer market. We show that empirical studies conducted at the product level are useful for investigating processes underlying product life cycles. We use hazard models with time-varying covariates to estimate the probability of product exit and Poisson models to estimate the probability of introduction. We measure the importance of different aspects of market structure, such as the degree of competitiveness, cannibalization, vintage, product niche and firm effects. We find some evidence of a relationship between the determinants of product exit and product entry.
