Short Videos, Big Self-Control Problems

I study how short-form design amplifies self-control problems in digital media. Short units repeatedly renew temptation that lasts longer than each unit, turning local temptation into sustained overconsumption. Using microdata from a U.S. short-drama platform, I exploit a nonlinear top-up menu to infer viewing plans and show that paying users watch 82.1% more than intended. Structural estimates imply an average temptation horizon of 11.2 minutes, short relative to the full drama but long relative to one-minute episodes. Counterfactuals show that larger decision units, default limits, and breaks improve long-run welfare. A short-video calibration highlights the broader welfare relevance.

That is from Renjie Bao of Princeton University. I believe a Princeton job market candidate? Via Quan Le.
