Sample size (or number of clusters) by treatment arms
Providing an exact sample size estimate for all potential constellations of job attribute values across job attributes is not meaningful given our conjoint design and research focus.
Below is our expected sample size by treatment arms for each of our eight job attributes:
1): “Total pay”
Attribute values: 3 with n = 3,000 in each.
Note: Our main analyses use a binary variable capturing “low” pay (n = 3,000) vs. “average” and “high” pay (n = 6,000).
2): “Performance bonuses”
Attribute values: 4 with n = 4,500 for “fixed salary” and n = 1,500 for each of the other three attribute values.
Note: Our main analyses use a binary variable capturing “Fixed salary” (n = 4,500) vs. “PfP” (n = 4,500; all three PfP attribute values).
3: “Job performance evaluation”
Attribute values: 4 with n = 2,250 in each.
Note: Our main analyses use a binary variable capturing “Supervisor” (n = 2,250) vs. “Performance goals” (n = 6,750; all three program goal attribute values).
4: “Current community involvement”
Attribute values: 3 with n = 3,000 in each.
Note: Our main analyses use a binary variable capturing “low” participation (n = 3,000) vs. “moderate” and “high” participation (n = 6,000).
5: “Community income”
Attribute values: 3 with n = 3,000 in each.
Note: Our main analyses use a binary variable capturing “low” income (n = 3,000) vs. “moderate” and “high” income (n = 6,000).
6: “Community demographics”
Attribute values: 4 with n = 2,250 in each.
Note: Our main analyses use a binary variable capturing “Mostly white” (n = 2,250) vs. “Mostly non-white” (n = 6,750; all three other attribute values).
7: “Overtime work”
Attribute values: 3 with n = 3,000 in each.
Note: Our main analyses use a binary variable capturing “Frequent” (n = 3,000) vs. “Occasional” and “Never” (n = 6,000).
8: “Key job task”
Attribute values: 4 with n = 2,250 in each.
Note: Our main analyses use a binary variable capturing “Collaboration with community groups/organizations” and “Direct interaction with community residents (n = 4,500) vs. “Analyses” and “Teamwork with peers” (n = 4,500).
