Abstract:

We propose a unified framework to investigate operations management problems for firms who sell multiple products to consumers with simultaneous and sequential search and choice behavior. We first characterize consumer purchase decision in the presence of search cost, substitution and complementary effects. Then, we develop optimal or near-optimal solutions for assortment planning and pricing for firms in different business scenarios. Our empirical study shows that the new solution framework can improve the goodness-of-fit and prediction accuracy for consumer choice, sales and revenue in the various scenarios, including multiple stores in different locations. Failure to account for the features in consumer search and choice may lead to substantial losses in operations management.
