This thesis contributes to the research on other regarding preferences by experimental studies. Chapter 1 investigates the feasibility of efficiency gains in a principal-agent relationship by voluntary leadership. Chapter 2 investigates whether negative reciprocity can be documented if the worse...

Numerous laboratory experiments show that workers reciprocate to high wages with high effort, when there is perfect information on the surplus created. Recent field experiments, however, suggest that trust and reciprocity may be lower or absent when the information is incomplete. We report a...

Constructing compensation schemes for effort in multi-dimensional tasks is complex, particularly when some dimensions are not easily observable. When incentive schemes contractually reward workers for easily observed measures, such as quantity produced, the standard model predicts that...
