Artificial Intelligence (AI) automates human decisions. Algorithmic pricing, a form of AI, sets prices by a computer. It is now common currency in ride-hailing, travel, drugs, gasoline, online goods---And great price variability characterizes all those settings. However, little is known about...

In-store shopping is a recurring behavior often happening in a stable context, making it very likely for the formation of habits. Relying on heuristics and habits can help consumers free up their mental resources for more important deliberative tasks. This is broadly consistent with the finding...

Despite the availability of multiple safe vaccines, vaccine hesitancy may present a challenge to successful control of the COVID-19 pandemic. As with many human behaviors, people’s vaccine acceptance may be affected by their beliefs about whether others will accept a vaccine(i.e., descriptive...

Abstract Estimating the effects of interventions in networks is complicated due to interference, such that the outcomes for one experimental unit may depend on the treatment assignments of other units. Familiar statistical formalism, experimental designs, and analysis methods assume the absence...

We study the calculation of exact p-values for a large class of non-sharp null hypotheses about treatment effects in a setting with data from experiments involving members of a single connected network. The class includes null hypotheses that limit the effect of one unit's treatment status on...

Social advertising uses information about consumers' peers, including peer affiliations with a brand, product, organization, etc., to target ads and contextualize their display. This approach can increase ad efficacy for two main reasons: peers' affiliations reflect unobserved consumer...
