The Beauty Premium
1. Employers thought beautiful people were more productive even when their only interaction was via a telephone interview. It appears that the confidence that beautiful people have in themselves comes across over the phone as well as in person.These results suggest that the beauty premium is not entirely rational on the part of employers. This seems to undercut the point of view advanced by my colleague Robert Barro a few years ago in this opinion piece.
2. Employers (wrongly) expect good-looking workers to perform better than their less-attractive counterparts under both visual and oral interaction, even after controlling for individual worker characteristics and worker confidence.
