We consider pricing problems when customers choose among the products according to the nested logit model and there is a quality consistency constraint on the prices charged for the products. We consider two types of quality consistency constraints. In the first type of constraint, there is an inherent ordering between the qualities of the products in a particular nest and the price for the pro...

Discrete choice models have been used for several decades to capture central features of customer preferences. In particular, they provide a compact expression of how product demand changes as the offered assortment changes in composition or price. Some models, such as the basic attraction model, have been justified with axioms; see [14]. Alternatively, models like the multinomial logit (MNL) m...

the expected revenue we obtain given that nest i is selected is Ri(wi) = P j∈N wij (κij−ηij logwij) P j∈N wij , where M = {1, . . . ,m}, N = {1, . . . , n} and γi ∈ [0, 1] measures product dissimilarity within nests. Due to a one-to-one relationship, control of the preference weights equates to control of the prices κij−ηij logwij , where 1/ηij represents product price sensitivity and κij/ηij r...

We propose a route choice model that relaxes the independence from irrelevant alternatives property of the logit model by allowing scale parameters to be link specific. Similar to the the recursive logit (RL) model proposed by Fosgerau et al. (2013), the choice of path is modelled as a sequence of link choices and the model does not require any sampling of choice sets. Furthermore, the model ca...

A novel approach is proposed to use the Cross Nested Logit (CNL) model in route choice when sampling of paths is considered. It adopts the Metropolis-Hasting algorithm to sample the choice sets for the model. A new expansion factor and an approximation method are put forward to calculate the sampled probabilities of alternatives. We build on state-of-the-art results for the Multivariate Extreme...

the objective of this study was to assess the level of knowledge of the turkish farmers with regard to fertilizer usage. farmers in the kazova district of turkey's tokat province were interviewed regarding their soil maintenance practices. the interview was based on a standardized questionnaire the answers being recorded at the time of interview. simple random sampling method was used to de...

Work zones are critical parts of the transportation infrastructure renewal process consisting of rehabilitation of roadways, maintenance, and utility work. Given the specific nature of a work zone (complex arrangements of traffic control devices and signs, narrow lanes, duration) a number of crashes occur with varying severities involving different vehicle sizes. In this paper we attempt to inv...

in recent decades, large investments have been made to introduce soil conservation methods, but most of these efforts have had limited success in achieving the goals. as a result, attempt to identify the factors deterring or promoting adoption of soil conservation practices is important. therefore, this study aimed to investigate factors affecting adoption of soil conservation practices by rain...
