'Women's pessimism about earning power boosts gender pay gap'
Women constantly underestimate themselves and their potential to earn, claim scientists who suggest that this behaviour may be thwarting efforts to end the gender pay gap.
The study from University of Bath in the UK finds that women underestimate their earnings prospects, leading to lower expectations and little inclination to push for higher wages or promotion, or seek a better paid position.
Conversely, men consistently overestimate their prospects.
When reality fails to live up to their optimistic expectations they are dissatisfied and more likely than women to try to engineer a pay rise or promotion, or change jobs in the pursuit of better pay.
The finding adds to the complex mix of causes of the gender pay gap reported as work, society and family, and calls into question the efficacy of policy measures to address the gap.
Despite being lower paid than men, it is well documented that women are more satisfied at work than their male counterparts.
Economists have been trying to explain the 'paradox of the contented female worker', or why women are happy at work despite pay inequality.
The findings are based on analysis from the British Household Panel Survey - a major longitudinal study - tracking individuals' expectations of salaries from unemployment to paid employment.
The results suggest men have a tendency to overestimate what they would be paid, while women underestimated their pay prospects, adding to the body of evidence that shows women underestimate their abilities, while men consistently overestimate their capabilities.
"If low female expectations in terms of pay is fuelled by a pessimistic outlook, then even without discrimination and progression-related issues, women will continue to underestimate themselves and continue to inadvertently accept pay inequality," said Chris Dawson, Senior Lecturer at University of Bath.
"It has serious implications for policy that is trying to address the gender pay gap and suggests more needs to be done to actively advance women at work, without relying on them to self-select for promotion and senior opportunities," Dawson said.
"The takeaway message of this research is not about putting the responsibility on women, but recognising that without policy measures to address this, we run the risk of never closing the gender pay gap," he said.
"Whilst the role of unconscious bias in gender relations in the workplace has been well documented, this new research demonstrates the role of unconscious pessimism and passivity on the part of women," said Veronica Hope Hailey, Dean of the University's School of Management.
"It shows the importance of people management practices that enable and encourage women to progress and recognise their value," she said.
The study was published in the Journal of Economic Behaviour and Organisation.
