The MovieLens Beliefs Dataset: Collecting Pre-Choice Data for Online Recommender Systems
Guy Aridor, Duarte Goncalves, Ruoyan Kong +2
An increasingly important aspect of designing recommender systems involves considering how recommendations will influence consumer choices. This paper addresses this issue by intro…
Speed, Accuracy, and Complexity
Duarte Gonçalves
This paper studies when response time is informative about problem complexity. It revisits a canonical sequential-sampling model in which a decision-maker chooses when to stop acqu…
Quantal Response Equilibrium with a Continuum of Types: Characterization and Nonparametric Identification
Evan Friedman, Duarte Gonçalves
Quantal response equilibrium (QRE), a statistical generalization of Nash equilibrium, is a standard benchmark in the analysis of experimental data. Despite its influence, nonparame…
Deconstructing the Filter Bubble: User Decision-Making and Recommender Systems
Guy Aridor, Duarte Goncalves, Shan Sikdar
We study a model of user decision-making in the context of recommender systems via numerical simulation. Our model provides an explanation for the findings of Nguyen, et. al (2014)…
