The price premium of generic pharmaceuticals to brand-names is examined under different competitive market situations. The result of this study shows that the number, market share, and the age of both brand-name and generic products have the most explanatory power for explaining the price premium. This study further applies this method to a pharmaceutical price index in order to explain 'Drug Price Index Perplexities.'
