Submitting queries to search engines has become a major way in which consumers search for information and products. The massive amount of search query data available today has the potential to provide valuable information on consumer preferences. In order to unlock this potential, it is...

We develop an incentive-aligned experimental paradigm to study how consumer purchase dynamics are affected by the interplay between the loyalty programs and the pricing and promotional strategies of competing firms. In our experiment, subjects made sequential choices between two competing...

We extend Latent Dirichlet Allocation (LDA) by introducing a topic model, Hierarchically Dual Latent Dirichlet Allocation (HDLDA), for contexts in which one type of documents (e.g., search queries) are semantically related to another type of documents (e.g., search results). In the context of...
