Abstract: | The role of consumption externalities is examined in the demand for pharmaceuticals at both the brand level and over a therapeutic class of drugs. Externalities emerge when use of a drug by others affects its value, and/or conveys information about efficacy and safety to patients and physicians. This can affect the rate of market diffusion for a new entrant, and can lead to dominance of one drug despite the availability of close subsitutes. Data for H2-antagonist antiulcer drugs is used to estimate a dynamic demand model and quantify these effects. |
