For our empirical analysis of the case with horizontally differentiated products we use the same data as in the case with vertically differentiated goods. Nevertheless we implement the differing model assumptions by defining the data sample properly. The empirical analysis proceeds as follows: After summarizing the theoretical results in multiple hypotheses (Section 5.1) the data sample and the implementation of the theoretical parameters in the data are described (Section 5.2). The results of the empirical estimations are presented in Section 5.3. Section 5.4 concludes. The empirical estimations presented in this chapter in large parts follow Zaby and Heger (2009).
