A randomised field experiment in Kenya uses differing levels of subsidies for an innovative bed net to suggest that temporary subsidies help short-term adoption rates of new (health) technologies and can perhaps have an effect on long-term adoption rates due to the learning experience.
In the context of a lab experiment replicating the job/hiring market, this study reveals that prior to affirmative action, women, including high-performing women, fail to enter the competition, thus the actual performance costs of affirmitive action are negligible. This implies that the long-term effects are positive, as increasing the representation of "minorities" may improve mentoring possibilities, and change the perception of "minorities'" ability to hold a high-ranking position.
This experiment, replicating the selection environment of competitive jobs, suggests that the gender gap could be due in part to men's overconfidence, and men's preferences for performing in competition. Further implications include that a surplus of low-performing men may too often self-select into these jobs while too many high-performing women do not.
An intervention that allowed randomly selected employees in a Chinese travel agency call centre to work from home appeared to have significant positive effects on worker performance.
