Here are three experiments that aim to capture the hidden costs of control. Agents get an initial endowment (like a salary), and the Principal's payoff depends on what the Agent sends back. The third experiment consists of five vignette stories, offered in a random order and with one out of four conditions per vignette (trust, human control, automated control, and monitoring). The installation instructions are on GitHub: https://github.com/AlexHartveld/otree-costs-of-control-questionnaire-mturk We also made this project to work with mTurk workers because we want to compare this population of automated control workers with the students from the original Falk & Kosfeld (2006) study.
