We study and model the process by which humans summarize creative documents (e.g., from a movie script to a synopsis). We develop a customized topic model based on Poisson Factorization and inspired by the creativity literature, which links the text in a summary to the text in the original document. Traditional Poisson Factorization approximates documents as positive combinations of topics, i.e., as points in the cone defined by a set of topics (in the Euclidean space defined by the words in the vocabulary).

Marketing research relies on individual-level estimates to understand the rich heterogeneity of consumers, firms, and products. While much of the literature focuses on capturing static cross-sectional heterogeneity, little research has been done on modeling dynamic heterogeneity, or the heterogeneous evolution of individual-level model parameters. In this work, the authors propose a novel framework for capturing the dynamics of heterogeneity, using individual-level, latent, Bayesian nonparametric Gaussian processes.

We study multi-period sales-force incentive contracting where salespeople can engage in effort gaming, a phenomenon that has extensive empirical support. Focusing on a repeated moral hazard scenario with two independent periods and a risk-neutral agent with limited liability, we conduct a theoretical investigation to understand which effort profiles the firm can expect under the optimal contract.

Once artificial intelligence (AI) is indistinguishable from human intelligence, and robots are highly similar in appearance and behavior to humans, there should be no reason to treat AI and robots differently from humans. However, even perfect AI and robots may still be subject to a bias (referred to as speciesism in this article), which will disadvantage them and be a barrier to their commercial adoption as chatbots, decision and recommendation systems, and staff in retail and service settings.

In this research, we investigate the prevalence, robustness and possible reasons underlying the polarity of online review distributions with the majority of the reviews at the positive end of the rating scale, a few reviews in the mid-range and some reviews at the negative end of the scale.

Submitting queries to search engines has become a major way for consumers to 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 necessary to understand how consumers translate their preferences into search queries. Strategic consumers should attempt to maximize the information content of the search results, conditional on a set of beliefs on how the search engine operates.

In light of consumers’ growing dependence on their smartphones, this article investigates the nature of the relationship that consumers form with their smartphone and its underlying mechanisms. We propose that in addition to obvious functional benefits, consumers in fact derive emotional benefits from their smartphone—in particular, feelings of psychological comfort and, if needed, actual stress relief. In other words, in a sense, smartphones are not unlike adult pacifiers.

At each stage in customers' journeys, they encounter different types of numeric information that they process using different judgment strategies. Relevant numbers might include budgets, price, product attributes, product counts, product ratings, numbers in brand names, health and nutrition information, financial information, time-related information, and others. This manuscript provides a review of the vast array of numerical information presented to consumers at different stages of the customer journey.

This research examines how drip pricing--a strategy whereby a firm advertises only part of a product's price upfront and then reveals additional mandatory or optional fees/surcharges as the consumer proceeds through the buying process--affects consumer choice and satisfaction. Across six studies, we find that when optional surcharges are dripped (vs. revealed upfront) consumers are more likely to initially select a lower base priced option which, after surcharges are included, is often more expensive than the alternative.
