Customer behavior is often assumed to follow weak rationality, which implies that adding a product to an assortment will not increase the choice probability of another product in that assortment. However, an increasing amount of research has revealed that customers are not necessarily rational when making decisions. In this paper, we propose a new nonparametric choice model that relaxes this assumption and can model a wider range of customer behavior, such as decoy effects between products. In… 
Assortment Optimization under the Decision Forest Model
TLDR
This paper proposes a methodology for solving the problem of finding the assortment that maximizes expected revenue under the decision forest model, and shows that the Benders subproblem can be solved efficiently by primal-dual greedy algorithms.
On the estimation of discrete choice models to capture irrational customer behaviors
TLDR
This work proposes an estimation method for the recently proposed Generalized Stochastic Preference choice model, which subsumes the family of Random Utility Maximization models and is capable of capturing halo effects, and shows how to use partially-ranked preferences to efficiently model rational and irrational customer types from transaction data.
The Use of Binary Choice Forests to Model and Estimate Discrete Choices
We show the equivalence of discrete choice models and the class of binary choice forests, which are random forests based on binary choice trees. This suggests that standard machine learning
When is Assortment Optimization Optimal?
TLDR
This paper introduces a mechanism design problem where the items have fixed prices and the seller optimizes over (randomized) allocations, given a distribution for how a buyer ranks the items, and derives a sufficient condition, based purely on the buyer’s preference distribution, that guarantees assortments to be optimal within the larger class of randomized mechanisms.
The Value of Robust Assortment Optimization Under Ranking-based Choice Models
The ranking-based choice model is a popular model in revenue management for predicting demand for a firm’s products based on the assortment of products that the firm offers to their customers.
Variety and Inventory Trade-off in Retailing: An Empirical Study
We investigate the trade-off between variety and inventory in retailing using a proprietary data set from a bookstore chain. In general, more variety is expected to generate higher traffic to store
Robust and Heterogenous Odds Ratio: Estimating Price Sensitivity for Unbought Items
Problem definition: Mining for heterogeneous responses to an intervention is a crucial step for data-driven operations, for instance to personalize treatment or pricing. We investigate how to

A Market Discovery Algorithm to Estimate a General Class of Nonparametric Choice Models
TLDR
A market discovery algorithm that starts with a parsimonious set of types and enlarge it by automatically generating new types that increase the likelihood value is proposed, which improves the root mean square errors between predicted and observed purchases computed under independent demand model estimates.
A Nonparametric Joint Assortment and Price Choice Model
TLDR
A tractable nonparametric expectation maximization (EM) algorithm is developed to fit the model to the aggregate transaction data and an efficient algorithm is designed to determine the profit-maximizing combination of offer set and price.
The Exponomial Choice Model: A New Alternative for Assortment and Price Optimization
TLDR
This work investigates the use of a canonical version of a discrete choice model due to Daganzo (1979) in optimal pricing and assortment planning and demonstrates how the EC model can be easily estimated---by establishing that the loglikelihood function is concave in model parameters and detailing an estimation example using real data.
