ON THE REPRESENTATION OF THE NESTED LOGIT MODEL
Published online by Cambridge University Press: 11 January 2021
Abstract
In this paper, we give a two-line proof of a long-standing conjecture of Ben-Akiva in his 1973 PhD thesis regarding the random utility representation of the nested logit model, thus providing a renewed and straightforward textbook treatment of that model. As an application, we provide a closed-form formula for the correlation between two Fréchet random variables coupled by a Gumbel copula.
