The National Bureau of Economic Research just published a paper on salary negotiations looking at the gender discrepancies. Andreas Leibbrandt and John List studied what was the tendency of someone to negotiate their salary. Here is their abstract:
One explanation advanced for the persistent gender pay differences in labor markets is that women
avoid salary negotiations. By using a natural field experiment that randomizes nearly 2,500 job-seekers
into jobs that vary important details of the labor contract, we are able to observe both the nature of
sorting and the extent of salary negotiations. We observe interesting data patterns. For example, we
find that when there is no explicit statement that wages are negotiable, men are more likely to negotiate
than women. However, when we explicitly mention the possibility that wages are negotiable, this difference
disappears, and even tends to reverse. In terms of sorting, we find that men in contrast to women prefer
job environments where the ‘rules of wage determination’ are ambiguous. This leads to the gender
gap being much more pronounced in jobs that leave negotiation of wage ambiguous.
Take home message:
Hypothesis is that women avoid salary negotiations.
In jobs where wages are not explicitly stated to be negotiable, men were more likely to negotiate.
In jobs where wages are negotiable, there is no difference between genders, or may be favourable for women.
Men prefer jobs where where their wage rules are ambiguous and thus gender pay gaps are much more pronounced.
So ladies, if we are to minimize the gender pay gap we need to make it a rule to negotiate our wages at every opportunity regardless of the rules.
