| Tiivistelmä: | The existence of a symmetric equilibrium with multiproduct firms using a nested logit model of demand is proved. The demand model is parametrized by two variables which characterize different dimensions of preference for variety. They reflect intragroup heterogeneity and intergroup heterogeneity, a group (or nest) being the set of products produced by a firm. There are then two dimensions to market performance; the total number of firms and the range of products produced per firm. It is shown that the market equilibrium involves an excessive number of firms, but each firm provides too few products. |
