Women in the UK on average earn less per hour than men. According to the Annual Survey of Hours and Earnings, the mean hourly pay for women in 2015 was 17.5% less than that for men. This figure is for all employees, full and part time. As far as full-time employees is concerned, the gap was slightly smaller at 13.9%. Nevertheless, as you can see from Table 6 in the linked Excel file, these gaps have decreased in recent years – but only slightly.
A recent paper from the Institute for Fiscal Studies has disaggregated the figures to give a better picture of this wage gap. It finds that having children is a major contributing factor to the gap. It also finds that this has a bigger impact on the earnings of graduates and those without a degree but with A levels.
On entry to the labour market, men and women earn roughly the same. People’s wages tend to rise during their 20s, but men’s rise slightly faster than women’s, causing a pay gap to open and widen – but slowly at first. Average (mean) men’s wages continue to grow during their 30s and a bit during their 40s. However, average women’s wages flatline. Thus the wage gap grows substantially, especially for the higher educated.
The paper argues that the arrival of children is a major contributing factor to this picture. It looks at the gap before and after the arrival of children. “The crucial observation is that the gap opens up gradually after the first child arrives and continues to widen for many years after that point.” By 12 years after the first child is born, the wage gap has widened to 33%.
The paper does not offer reasons for the small gap that exists before the arrival of children. But it does give possible reasons for the widening gap after having children. A major one, it suggests, has to do with labour market experience.
“As women are likely to do less paid work after the arrival of children, the level of labour market experience they have falls further and further behind that of their male counterparts, and the wage gap therefore widens.” They may also miss out on promotions.
Each year a woman spends away from the labour market is associated with an average 2% drop in pay compared with those who remain in work. For those with at least A levels, the penalty is 4%; but there is no drop in pay for those without A levels.
Other possible explanations include mothers taking work that requires a lower skill level, and at lower hourly pay, in order to gain flexibility in working hours. However, the evidence suggests that women who move to part-time work on having a child suffer no immediate drop in pay. But their hourly pay does grow more slowly, thus contributing to a widening of the gap.
Another explanation is employers exercising market power to discriminate against women with children. The paper does not consider this explanation.
The articles discussing the paper look at policy implications and identify various things that can be done to narrow the gap. Read the paper and articles and try answering the questions below.

In the following article, Joseph Stiglitz argues that power rather than competition is a better starting point for analysing the working of capitalism. People’s rewards depend less on their marginal product than on their power over labour or capital (or lack of it).
As inequality has widened and concerns about it have grown, the competitive school, viewing individual returns in terms of marginal product, has become increasingly unable to explain how the economy works.
Thus the huge bonuses, often of millions of pounds per year, paid to many CEOs and other senior executives, are more a reflection of their power to set their bonuses, rather than of their contribution to their firms’ profitability. And these excessive rewards are not competed away.
Stiglitz examines how changes in technology and economic structure have led to the increase in power. Firms are more able to erect barriers to entry; network economies give advantages to incumbents; many firms, such as banks, are able to lobby governments to protect their market position; and many governments allow powerful vested interests to remain unchecked in the mistaken belief that market forces will provide the brakes on the accumulation and abuse of power. Monopoly profits persist and there is too little competition to erode them. Inequality deepens.
According to Stiglitz, the rationale for laissez-faire disappears if markets are based on entrenched power and exploitation.

Research published by the Institute for Fiscal Studies shows that graduates from wealthier family backgrounds earn significantly more than those from poorer backgrounds. If you compare the 20% of graduates from the richest backgrounds with the remaining 80%, the average earnings gap in 2012/13, 10 years after graduation, was £8000 per year for men and £5300 for women. Even when you take graduates in similar degrees from similar universities, there is still a gap of around 10% between those from richer and those from poorer backgrounds.
The research also shows that in 2012/13, 10 years after graduation, the median earnings for economics graduates was the second highest of any subject (just behind graduates in medicine) and that at the 90th percentile economics graduates had the highest earnings (£93 900 for women and £121 400 for men) of any subject. In fact, graduates in economics were the only males at this percentile earning over £100 000. (Click here for a PowerPoint of the chart.) As the Press Release to the IFS working paper states:
For males, it is estimated that approximately 12% of economics graduates earned above £100 000 some ten years after graduation; by contrast,
6% of those studying medicine or law earned more than £100 000.
For females, it is estimated that approximately 9% of economics graduates earned above £100 000 some ten years after graduation; by contrast, just 1% of those studying medicine and 3% of those studying law did so.
For some subjects, graduates earned little more than non-graduates.
Those studying the creative arts had the lowest earnings, and indeed earned no more on average than non-graduates.
The research also shows that earnings vary substantially by gender and university. For those earning £8000 or more, the median earnings for male graduates 10 years after graduation was £30 000 (compared with £21 000 for non-graduates), whereas for women it was £27 000 (compared with £18 000 for non-graduates).
Earnings are substantially higher for graduates from some universities, such as Oxford, Cambridge and the LSE. “At the other end of the spectrum, there were some institutions (23 for men and 9 for women) where the median graduate earnings were less than those of the median non-graduate ten years on.” Differences in graduate earnings by university tend to compound the difference by students’ family background as those from poorer backgrounds disproportionately attend universities with lower average graduate earnings by discipline.

The earnings gap between men and women is well-documented and depending on how we measure it, we get different figures. One of the most common measures is mean earnings per hour. The latest estimates suggest that women are paid around 20% less than men, though other data does give lower figures. Though actions have been taken to reduce the inequality between men and women, it still persists in many areas and this has led to plans for new league tables from Nicky Morgan.
The inequality gap has certainly come down. Back in 1970, the wage differential was around 37 per cent, so progress has been made, although the wage gap in the UK has stabilised somewhat. The gender wage gap is at least in part explained by occupations, as women have tended to be prevalent in some of the more poorly paid occupations. However, significant earnings differentials still exist within occupations. We see fewer women in the more senior positions; women tend to take career breaks and hence this can cause more investment into training and promoting men. Furthermore, we often simply see some form of prejudice or discrimination whereby women are just paid less than men, despite the Equal Pay Act.
As a means of combatting this inequality, Nicky Morgan, the Women and Equalities Minister, has announced plans that will require private companies and voluntary organisations employing more than 250 workers to reveal their pay gap. They will have to produce this information online and this will a means to bring down the inequality that exists between men and women in the same occupations. The first League Table of this pay gap will be published in April 2018 so companies will have to begin compiling the information from April 2017. This has received criticism from some, as it is not starting soon enough, but it is seen as a step in the right direction.
Carolyn Fairbairn, CBI Director-General warned that these League Tables shouldn’t be used to name and shame firms, as many factors might explain wage differentials. She noted:
“Where reporting can be useful is as a prompt for companies to ask the right questions about how they can eradicate the gender pay gap … The government should consult closely with business to ensure that this new legislation helps close the gender pay gap, rather than ending up as a box-ticking exercise.”
Clearly there are some close links between the gender pay gap and concerns about poverty and minimum wages and although the League Tables perhaps should not be used to name and shame, one might think it is inevitable that this is how they will be viewed.

Questions
- Use a labour market diagram to explain how gender pay gaps can emerge based on different marginal products.
- How can gender pay gaps emerge because of women taking career breaks and being less geographically mobile?
- Use information on the ONS website to compare pay differentials across occupations. Are the biggest and smallest differentials where you would expect?
- There are numerous reasons why men have traditionally been paid more than women. Which reasons could be said to be irrational and which are rational?
- If employers were forced to give genuinely equal pay for equal work, how would this affect the employment of women and men? What would determine the magnitude of these effects?
- Do you think this naming and shaming will be effective in reducing the gender pay gap amongst the largest companies? Can you suggest any other policy options?
- If the Equal Pay Act is in place, why can companies still pay women less?
There are countless people who work 12-hour days – some get rewarded with huge salaries, while others are paid peanuts. A key question is: are these people happy? With 24 hours in a day for both rich and poor, the more hours we work, the fewer hours we have for leisure time. So, how do we choose the optimal work-life balance?
In economics, we often talk about the concept of diminishing marginal utility and this concept can be applied to working life. For many people, each additional hour worked is tougher or adds less to your utility – we get tired, bored and the job may seem more unpleasant the more hours you work. The typical day of work is around 7-8 hours, but across Sweden, some offices are now closing at 3.30, with a 6-hour working day, but with salaries remaining the same. 
It’s not a new idea in Sweden and trials of this shorter working day concept have proved successful, with higher reported profits, better service to customers (or patients) and happier, more productive staff.
This shorter working day is not a common occurrence across Sweden or other countries, but it’s a practice that is certainly garnering media attention. Companies will certainly be keen if this means an increase in productivity, but one key concern will be the potential loss of business from companies who do keep working after 3.30 and expect phones to be answered.
It would certainly be an attractive prospect for employees and perhaps is a good way of ‘poaching’ the best staff and hence of boosting worker productivity. With more free time, perhaps an employee’s happiness would also increase, which could have significant effects on a range of variables. The following article considers this shorter working day.
The truth about Sweden’s short working hours BBC News, Maddy Savage (2/11/15)
Questions
- Explain the concept of diminishing marginal utility with respect to hours worked. Can this be used to explain why overtime often receives higher rates of pay?
- Using indifference analysis, explain how a change in the number of hours worked might affect an individual’s happiness.
- Why might a shorter working day help to increase a firm’s profits?
- If a shorter working day did increase happiness, what other factors might be affected? Does this explain why other countries are so interested in the success of this initiative?
