Unsold perishable food waste costs retailers and generates greenhouse gases. New stores face a “cold start” problem of what and how much to stock but can reduce waste by nearly two-thirds within two years. Regulators and investors need to allow for some waste as part of this dynamic learning process.
Analyzes data from a Japanese grocery chain on perishable food product ordering, sales and waste to determine whether—and how quickly—new stores can learn to match local demand and reduce waste.
Policies like the U.S. Affordable Care Act extend economic access to healthcare but may also change the criteria consumers use to judge the risks and benefits of medical procedures. Extending coverage can signal reduced risk in—and preference for—otherwise high-risk procedures, potentially impacting insurers, healthcare providers and consumers themselves.
Explores whether extending insurance coverage alters consumer perceptions of key medical decision-making criteria, increasing their perceptions of the safety and efficacy of medical therapies and making them more likely to choose covered high-risk procedures.
A Bayesian model integrating multiple marketing interventions over time combines the causal-inference advantages of randomized experimentation with the longitudinal richness of repeated observational data. Results reveal that marketing effectiveness depends much more on customer receptivity than campaign design or timing, pointing to the need for—and means of—better targeting.
Develops and tests a Bayesian model integrating multiple marketing interventions over time that combines the causal-inference advantages of randomized experimentation with the longitudinal richness of repeated observational data to support improved targeting.
Privacy regulations require consent to use tracking “cookies,” but how consumers respond depends on the choice architecture of notifications. Most currently “accept all” or incorrectly assume that dismissing a notice rejects all. Interfaces that clearly display all options or a universal browser setting that applies across websites maximize consumer welfare.
Uses a online field experiment to determine how consumers respond to different cookie consent banner designs: deliberate obstruction (hiding options behind extra clicks); reordering (placing preferred options first); and differential highlighting (using color to emphasize certain choices).
