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...

Two distinctly different nested logit models have been widely used in both research and applications. The differences, not widely recognized, between these models will substantially influence estimation results, behavioral interpretation and policy analysis. The McFadden nested logit model is...

This research focuses on the convergence error inherent in the predictions of network equilibrium flows obtained from the Frank-Wolfe algorithm. Factors which determine the magnitude of the convergence error are identified. The effects of selection of a stopping criterion and an initial solution...

The assumption of independently and identically distributed (IID) error terms in the Multinomial Logit (MNL) model leads to its infamous IIA property. Relaxation of the IID assumption has been undertaken along a number of isolated dimensions leading to the development of a rich set of discrete...

The transferability of disaggregate choice models has received considerable attention in recent years. Past studies observe varying levels of model transferability but do not characterize the conditions which lead to high or low levels of transferability. Differences in transferability appear to...

This paper proposes a new approach to the optimal allocation of airline seats among itineraries in a network under stochastic demand. Current approaches to network seat inventory control are based on either full assignment or bucket control. Under full assignment, all seats on each flight leg...
