Transitions requires individual …-level risk-taking in pursuing productivity-enhancing activities including using and developing new knowledge. Individual …-level, idiosyncratic risk implies that distinct risk-sharing institutions - even those providing the same level of insurance - can lead to …

We use experiments to test comparative statics predictions of canonical tournament theory. Both the roles of principal … tournament design. Consistent with theory, we observed an incentive effect from raising the winner's prize. However, we also … observed several empirical puzzles that appeared to contradict theory. Controlling for social preferences did not resolve the …
