Abstract

This paper investigates the demand for prescription pharmaceuticals at the retail level. We use complete demand systems to investigate elasticity for major classes of pharmaceuticals. We estimate both a regular and an inverse demand system using a differential version of the Rotterdam model. We find that both systems yield negative, and statistically significant own-price elasticities. The results indicate that pharmaceutical demand curves are not perfectly inelastic as some industry commentators suggest. We use the results of the complete demand system and a variant of a formula developed by Balk (1990) to derive a cost-of-living subindex for retail pharmaceuticals. We find that retail pharmaceutical prices using our index rise faster than wholesale prices, calculated either by the BLS or by the methods developed by Berndt et al.(1993).
