Research shows that women are more reticent than men to negotiate their salary offers. For instance, one study of graduating MBA students found that half of the men had negotiated their job offers as compared to only one eighth of the women. This general pattern has been replicated in survey studies of working adults and in laboratory experiments. It begs the question: Why? Is this a “confidence” problem? Is negotiation a skill for which men are simply better socialized than women? Why leave money on the table?
