Income and the use of prescription drugs for near retirement individuals

In this paper we estimate how demand for prescription drugs varies with income for a sample of near retirement individuals. The analysis is based on a novel panel data set with information about the purchase of prescription drugs for a large number of Danish individuals over the period 1995-2003. Our preferred model performs better in an external validation test than models that can be estimated on cross section data. Results indicate that demand does respond to variations in income and that reforms affecting income will therefore affect the use of prescription drugs.
