abecause the human may deviate from random assignment, especially when instructed to tweak resumes to better fit the position (as in Bertrand and Mullainathan 2004). 因为人也许从任意任务偏离,特别是当指示扭捏简历改善适合位置时(和在Bertrand和Mullainathan 2004年)。[translate]...
Randomization: Allows researchers to choose which treatment subjects will receive. Allows researchers to ensure that the observed outcomes are due to treatment. Allows subjects to choose which treatment they will receive. Does randomization reduce variability? With a randomized block design, the experiment...
Data was analyzed in R (i.e., using lme4107). To examine whether competency of the recipient of help influences the type of help children provide, a logistic linear mixed-effects model was preregistered including a random intercept and random slope for competency. However, these models resulted...

Inspired by the increasing use of artificial intelligence (AI) to augment humans, researchers have studied human–AI systems involving different tasks, systems and populations. Despite such a large body of work, we lack a broad conceptual understanding o
Organizational learning begins with experience. However, it remains an open question whether firms learn from a particular type of experience: exporting. T
