Participants act as employers and are presented with a total of 30 worker profiles. For varying tasks they are asked to state the maximum wage offer they would be willing to pay for each profile. Their compensation is linked to the actual productivity of workers.
We furthermore randomize whether worker are paid when being hired.

Experiment Characteristics

Sample size: planned number of clusters
There are no clusters to be randomized.
Sample size: planned number of observations
Our target sample size is 1100 participants. Each participants will make 30 wage offer decisions.

Participants are randomized in equal share to the worker bonus and control group.

In addition, we randomly assign participants to make wage offer decisions for two of the tasks (after everyone initially completes the main hiring task).
Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
