Abstract

In this paper we study the demand and supply of erythropoietin in four Nordic countries, using an econometric model based on discrete choice and a random utility model. It measures the effect of price changes as well as the loyalty of patients and physicians to a drug. Our main aims are to estimate demand for EPO and to determine the degree of competition in this Nordic market. The main motivation for this paper is to analyze the impact of product innovation on market power and welfare, e.g. on consumer and producer surplus. The product innovation is the entry of Aranesp in the Nordic market.
