This paper studies a Stated Preference (SP) experiment on the choice of type of (Rail) season card, conducted among current Dutch Railways season cardholders. They were asked to choose from the following three alternatives: (1) an unrestricted season card, (2) a cheaper season card with peak travel and travel frequency restrictions, and (3) not buying a season card. Multinomial logit (MNL), nes...

We study firms compatibility decisions in a horizontal differentiation model with network externalities. By means of a nested multinomial logit demand structure, we describe the trade-off between network externalities and product differentiation. Simple and general results are derived, which hold for any finite number of firms and which account for any functional form of the externality functio...

Logit kernel is a discrete choice model that has both probit-like disturbances as well as an additive i.i.d. extreme value (or Gumbel) disturbance à la multinomial logit. The result is an intuitive, practical, and powerful model that combines the flexibility of probit with the tractability of logit. For this reason, logit kernel has been deemed the “model of the future” and is becoming extremel...

We study assortment optimization problems when customers choose under the multinomial logit model with nested considerations sets. In this choice model, there are multiple customer types and a customer of a particular type is interested in purchasing only a particular subset of products. We use the term consideration set to refer to the subset of products that a customer of a particular type is...

The Independence of Irrelevant Alternatives (IIA) property of the multinomial logit (MNL) model imposes the restriction of zero covariance between the utilities of pairs of alternatives. This restriction is inappropriate for many choice situations; those in which some pairs or sets of alternatives share the same unobserved attributes. The nested logit (NL) model relaxes the zero covariance rest...

Swiss metropolitan areas are comprised of a system of communities with considerable fiscal autonomy. This study investigates how the income tax differentials across communities in an urban area affect the households` location decisions. Data from the urban agglomeration of Basel for the year 1997 is used. This unique data set contains tax information from all households that moved either within...
