Experimental Design

Experimental Design
Between subjects design.
Experimental Design Details
The experiment consists of six steps, three of which administrative or procedural (the random allocation assignment of an economic incentive mechanism). The actual laboratory study consists of three steps, (1) the filling in of standardized questionnaires and behavioral economic games, (2) an incentivized real-effort task and (3) the completion of a final questionnaire.
Randomization Method
Treatments randomized by laboratory computer software.
