Choice set generation within the generalized extreme value family of discrete choice models

摘要

This paper introduces a new member of the generalized extreme value(GEV)family of discrete choice models that directly incorporates choice set generation modeling into the specification via the GEV gen- erating function. Though still a two-stage model of choice set generation and choice, the proposed model specifies choice set generation endogenously and directly reflective of preferences, which further differen- tiates it from extant models of choice set formation. The properties of the model, denominated GenL (choice set Generation Logit), are examined in detail.
