The current note summarizes the findings of our nested Logit analysis of the use of health care services in Cameroon. The objectives of that analysis were: (i) identify the determinants of the choice of health care providers in Cameroon, and (ii) determine the compensation to the poor to get them away from traditional/self healing. For that purpose a nested Logit model was built to account for ...

We study the problem of finding an optimal assortment products maximizing expected revenue, in which customer preferences are modeled using a nested logit choice model. This is known to be polynomially solvable specific case and NP-hard otherwise, with only approximation algorithms existing literature. provide exact general method that embeds tailored Branch-and-Bound algorithm into fractional ...

When valuing water resources using multiple site recreation data, it is typical to observe many corner solutions. We present as a benchmark a theoretical model of recreation choice when corners are present, and assess the degree to which several empirical specifications match the benchmark. As an illustration, we estimate and compare the repeated nested logit, a random parameters repeated neste...

The emergence of Intelligent Transportation Systems and the associated technologies has increased the need for complex models and algorithms. Namely, real-time information systems, directly influencing transportation demand, must be supported by detailed behavioral models capturing travel and driving decisions. Discrete choice models methodology provide an appropriate framework to capture such ...

Nested logit is increasingly advocated as a tool of recreational demand and benefit estimation. The intent of this short monograph is to lay out, in a simple fashion, the theory behind the nested-logit model of site choice and the nested-logit model of participation and site choice. Rigorous but straightforward derivations of the properties of nested-logit models are provided, including the pro...

We study capacitated assortment problems when customers choose under the multinomial logit model with nested consideration 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 i...

Abstract-A discrete choice model is presented that explicitly recognizes differences in the error structure associated with a single “oddball” alternative within the choice set that has properties not common to the other alternatives. The model purportedly resolves questions related to the use of alternative-specific variables in transportation choice models to capture the effects of attributes...
