Abstract
Sutton (1998) offers us a simple way to model firm size distributions across differentiated products industries. We analyse the implications of this approach for company markups using a structural model for a specific industry. We incorporate the complexities of multi-product (brand) companies operating with different (strategic) configurations of product characteristics and stores to estimate brand markups, using Irish AC Nielsen retail data for Carbonated Soft Drinks. As a second step we estimate that market power does not increase in companies with higher market share, controlling for other factors. This challenges a traditional mind-set.
