  • Notes: In Columns 1–3, the unit of observation is one project. In Columns 4–12, the unit of observation is a 14 day pre‐ or post‐test period. In addition to the variables reported, all models include year dummies and cumulative (arsinh‐transformed) dollars earned on the platform. “Baseline” refers to the mean of the dependent variable. Standard errors are clustered on the worker level. The significance levels in all specifications are: *** = 0.1%, ** = 1%, * = 5%, and + = 10%.
