| Tiivistelmä: | The relationship between two families of models of product differentiation is investigated. The main result is that every model belonging to a very large class of Hotelling-type models of horizontal differentiation is actually a special case of a vertical product differentiation model. The defining characteristic of vertical product differentiation is that all consumers have the same ranking of the variants of a product. In the case of horizontal product differentiation, there is no such "natural" ranking of the variants. In spite of these different definitions , it can be shown that the equilibria emerging in the two categories of models are identical in a well defined sense. |
