Curious as to how the control group monthly amount ($50) was decided upon. Was it basically an incentive for those selected to participate?

- Digory 9y agoI wonder if it has anything to do with the $600 1099 floor. Staying below that might encourage under-reporting on taxes; staying above that gives the researchers pretty reliable addresses and SSNs from participants.
- jessriedel 9y agoI would speculate yes. (1) You want subjects in the control group to be incentivized to maintain contact with the researchers throughout the study and be willing to spend time answering their questions. (2) Whenever feasible, you want all subjects in a research study to be better off than not participating in the study. (3) It also controls for some minor confounding effects like "gets in the habit of going to the bank monthly and cashing a check".
