Experimental Details

Interventions

Intervention(s)
A control device is implemented in a natural work environment. We will investigate how workers react to such an implementation of control: Is there a negative behavioural reaction, i.e. do workers lower their effort once control is implemented?

Two groups:
1. Control group - incomplete contract (no control device)
2. Treatment group - contract with a minimum performance requirement (a imperfect control device)
Intervention Start Date
2018-12-10
Intervention End Date
2020-03-12

Primary Outcomes

Primary Outcomes (end points)
Primary outcome is how workers performance is affected by the random assignment to the control and treatment group. Hence, key outcome variable is workers performance. For further details, please refer to the pre-analysis plan.
Primary Outcomes (explanation)
For further details, please refer to the pre-analysis plan.

Secondary Outcomes

Secondary Outcomes (end points)
For further details, please refer to the pre-analysis plan.
Secondary Outcomes (explanation)

Experimental Design

Experimental Design
The (public) description of the experimental design is kept to its minimum to avoid experimenter demand effects. The (hidden) description will become public once the study is completed and will help you to understand the design in further detail.

In short, in a real labor market, we create two groups: One group receives an incomplete contract and is not subject no any controlling or monitoring device. The other group receives a more complete contract with a minimum performance requirement as a control device. First, all workers are assigned to an incomplete contract (HIT1). In a second stage, workers are assigned to one of the two mentioned groups (HIT2) and perform again a real-effort task.
Experimental Design Details
For further details, please refer to the pre-analysis plan.
Randomization Method
Randomization done by a computer software (Otree).
Randomization Unit
Individual
Was the treatment clustered?
No
