We study the impact of information manipulation by a principal on the agent's effort. In a context of asymmetric … information at the principal's advantage, we test experimentally the principal's willingness to bias (overestimate or under …-estimate) the information she gives to her agent on his ability in order to motivate him to exert more effort. We find that i …

We devise an experiment to explore the effect of different degrees of bargaining power on the design and the selection … of contracts in a hidden-information context. In our benchmark case, each principal is matched with one agent of unknown … number of agents because competition reduces the agents' informational monopoly power. However, this environment also …

Participants are given information about the gender of the co-participant they are …-participant directly influences men's choices (men compete less against other men than against women), but only when the gender information … is made sufficiently salient. A higher predicted competitiveness of women induces more competition. Giving stronger …

The 'ratchet effect' refers to a situation where a principal uses private information that is revealed by an agent … competition for principals or agents. While we do observe substantial and significant ratchet effects in the baseline (no … competition) case of our model, we find that ratchet behavior is nearly eliminated by labor-market competition ; interestingly …
