Raising the minimum wage: its effects on poverty and employment

The first Budget of the new UK Labour government was announced on 30 October 2024. It contained a number of measures that will help to tackle inequality. These include extra spending on health and education. This will benefit households on lower incomes the most as a percentage of net income. Increases in tax, by contrast, will be paid predominantly by those on higher incomes. The Chart opposite (taken from the Budget Report) illustrates this. It shows that the poorest 10% will benefit from the largest percentage gain, while the richest 10% will be the only decile that loses.

But one of the major ways of tackling inequality and poverty was raising the minimum wage. The so-called ‘National Living Wage (NLW)’, paid to those aged 21 and over, will rise in April by 6.7% – from £11.44 to £12.41 per hour. The minimum wage paid to those aged 18 to 20 will rise 16.3% from £8.60 to £10.00 and for 16 and 17 year-olds and apprentices it will rise £18% from £6.40 to £7.55.

It has been an objective of governments for several years to relate the minimum wage to the median wage. In 2015, the Conservative Government set a target of raising the minimum wage rate to 60 per cent of median hourly earnings by 2020. When that target was hit a new one was set to reach two-thirds of median hourly earnings by 2024.

The Labour government has set a new remit for the minimum wage (NLW). There are two floors. The first is the previously agreed one, that the NLW should be at least two-thirds of median hourly earnings; the second is that it should fully compensate for cost of living rises and for expected inflation up to March 2026. The new rate of £12.41 will meet both criteria. According to the Low Pay Commission, ‘Wages have risen faster than inflation over the past 12 months, and are forecast to continue to do so up to March 2026’. This makes the first floor the dominant one: meeting the first floor automatically meets the second.

How effective is the minimum wage in reducing poverty and inequality?

Figure 1 shows the growth in minimum wage rates since their introduction in 1999. The figures are real figures (i.e. after taking into account CPI inflation) and are expressed as an index, with 1999 = 100. The chart also shows the growth in real median hourly pay. (Click here for a Powerpoint.)

As you can see, the growth in real minimum wage rates has considerably exceeded the growth in real median hourly pay. This has had a substantial effect on raising the incomes of the poorest workers and thereby has helped to reduce poverty and inequality.

The UK minimum wage compares relatively favourably with other high-income economies. Figure 2 shows minimum wage rates in 12 high-income countries in 2023 – the latest year for which data are available. (Click here for a PowerPoint.) The red bars (striped) show hourly minimum wage rates in US dollars at purchasing-power parity (PPP) rates. PPP rates correct current exchange rates to reflect the purchasing power of each country’s currency. The blue bars (plain) show minimum wage rates as a percentage of the median wage rate. In 2023 the UK had the fourth highest minimum wage of the 12 countries on this measure (59.6%). As we have seen above, the 2025 rate is expected to be 2/3 of the median rate.

Minimum wages are just one mechanism for reducing poverty and inequality. Others include the use of the tax and benefit system to redistribute incomes. The direct provision of services, such as health, education and housing at affordable rents can make a significant difference and, as we have seen, have been a major focus of the October 2024 Budget.

The government has been criticised, however, for not removing the two-child limit to extra benefits in Universal Credit (introduced in 2017). The cap clearly disadvantages poor families with more than two children. What is more, for workers on Universal Credit, more than half of the gains from the higher minimum wages will lost because they will result in lower benefit entitlement. Also the freeze in (nominal) personal income tax allowances will mean more poor people will pay tax even with no rise in real incomes.

Effects on employment: analysis

A worry about raising the minimum wage rate is that it could reduce employment in firms already paying the minimum wage and thus facing a wage rise.

In the case of a firm operating in competitive labour and goods markets, the demand for low-skilled workers is relatively wage sensitive. Any rise in wage rates, and hence prices, by this firm alone would lead to a large fall in sales and hence in employment.

This is illustrated in Figure 3 (click here for a PowerPoint). Assume that the minimum wage is initially the equilibrium wage rate We. Now assume that the minimum wage is raised to Wmin. This will cause a surplus of labour (i.e. unemployment) of Q3 – Q2. Labour supply rises from Q1 to Q3 and the demand for labour falls from Q1 to Q2.

But, given that all firms face the minimum wage, individual employers are more able to pass on higher wages in higher prices, knowing that their competitors are doing the same. The quantity of labour demanded in any given market will not fall so much – the demand is less wage elastic; and the quantity of labour supplied in any given market will rise less – the supply is less wage elastic. Any unemployment will be less than that illustrated in Figure 3. If, at the same time, the economy expands so that the demand-for-labour curve shifts to the right, there may be no unemployment at all.

When employers have a degree of monopsony power, it is not even certain that they would want to reduce employment. This is illustrated in Figure 4: click here for a PowerPoint (you can skip this section if you are not familiar with the analysis).

Assume initially that there is no minimum wage. The supply of labour to the monopsony employer is given by curve SL1, which is also the average cost of labour ACL1. A higher employment by the firm will drive up the wage; a lower employment will drive it down. This gives a marginal cost of labour curve of MCL1. Profit-maximising employment will be Q1, where the marginal cost of labour equals the marginal revenue product of labour (MRPL). The wage, given by the SL1 (=ACL1) line will be W1.

Now assume that there is a minimum wage. Assume also that the initial minimum wage is at or below W1. The profit-maximising employment is thus Q1 at a wage rate of W1.

The minimum wage can be be raised as high as W2 and the firm will still want to employ as many workers as at W1. The point is that the firm can no longer drive down the wage rate by employing fewer workers, and so the ACL1 curve becomes horizontal at the new minimum wage and hence will be the same as the MCL curve (MCL2 = ACL2). Profit-maximising employment will be where the MRPL curve equals this horizontal MCL curve. The incentive to cut its workforce, therefore, has been removed.

Again, if we extend the analysis to the whole economy, a rise in the minimum wage will be partly passed on in higher prices or stimulate employers to increase labour productivity. The effect will be to shift the (MRPL) curve upwards to the right, thereby allowing the firm to pass on higher wages and reducing any incentive to reduce employment.

Effects on employment: evidence

There is little evidence that raising the minimum wage in stages will create unemployment, although it may cause some redeployment. In the Low Pay Commission’s 2019 report, 20 years of the National Minimum Wage (see link below), it stated that since 2000 it had commissioned more than 30 research projects looking at the NMW’s effects on hours and employment and had found no strong evidence of negative effects. Employers had adjusted to minimum wages in various ways. These included reducing profits, increasing prices and restructuring their business and workforce.

Along with our commissioned work, other economists have examined the employment effects of the NMW in the UK and have for the most part found no impact. This is consistent with international evidence suggesting that carefully set minimum wages do not have noticeable employment effects. While some jobs may be lost following a minimum wage increase, increasing employment elsewhere offsets this. (p.20)

There is general agreement, however, that a very large increase in minimum wages will impact on employment. This, however, should not be relevant to the rise in the NLW from £11.44 to £12.41 per hour in April 2025, which represents a real rise of around 4.5%. This at worst should have only a modest effect on employment and could be offset by economic growth.

What, however, has concerned commentators more is the rise in employers’ National Insurance contributions (NICs) that were announced in the Budget. In April 2025, the rate will increase from 13.8% to 15%. Employers’ NICs are paid for each employee on all wages above a certain annual threshold. This threshold will fall in April from £9100 to £5000. So the cost to an employer of an employee earning £38 000 per annum in 2024/25 would be £38 000 + ((£38 000 – £9100) × 0.138) = £41 988.20. For the year 2025/26 it will rise to £38 000 + ((£38 000 – £5000) × 0.15) = £42 950. This is a rise of 2.29%. (Note that £38 000 will be approximately the median wage in 2025/26.)

However, for employees on the new minimum wage, the percentage rise in employer NICs will be somewhat higher. A person on the new NLW of £12.41, working 40 hours per week and 52 weeks per year (assuming paid holidays), will earn an annual wage of £25 812.80. Under the old employer NIC rates, the employer would have paid (£25 812.80 + (£25 812.80 – £9100) × 0.138) = £28 119.17. For the year 2025/26, it will rise to £25 812.80 + ((£25 812.80 – £5000) × 0.15) = £28 934.72. This is a rise of 2.90%.

This larger percentage rise in employers’ wage costs for people on minimum wages than those on median wages, when combined with the rise in the NLW, could have an impact on the employment of those on minimum wages. Whether it does or not will depend on how rapid growth is and how much employers can absorb the extra costs through greater productivity and/or passing on the costs to their customers.

Got milk?

You’ll be familiar with these types of posts from me, which typically start with a comment like: ‘On my commute to work on …’. That’s one of the good things about a long drive – the interesting and informative discussions that you hear on the radio. This one is another interesting piece from BBC Radio 4, looking at a very topical issue, especially to those living in the South West and other rural areas in the UK.

We have recently seen pictures of farmers protesting about the price of milk and in places like Somerset, the protest took a rather odd method, where farmers from across the region entered supermarkets and simply bought all of the milk, before giving it away. The issue is that dairy farming is no longer profitable, as the price that dairy farmers receive for each pint of milk is now lower than the cost of providing it. Thus, for each pint they make a loss.

There are many reasons that have contributed to this situation, including pressures imposed by customers demanding cheaper prices; pressures from supermarkets using their monopsony power to force down the prices paid to farmers; and pressures from abroad. In the case of milk, we have a surplus and with a perishable product, i.e. one that cannot be stored, unlike wheat, this has contributed to falling prices. Data suggest that we are seeing approximately one farmer per day being forced to leave the indsutry.

This programme explores the current dairy farming crisis and draws some similarities with the wheat crisis that the UK experienced in the 1930s. The programme below is 30 minutes and provides some interesting insights on two important commodities and the economics behind the markets.

Today’s crisis in dairy farming and the wheat crisis of the 1930s BBC Radio 4; The Long View, Jonathan Freedland (29/9/15)

Questions

  1. Using demand and supply analysis, explain the situation in the milk market.
  2. Now consider the wheat industry and provide a similar analysis of how prices are set and what caused the problems seen in the 1930s.
  3. Although these two commodities have similarities they are also very different. Why can two different commodities experience such similar problems at such different times?
  4. What are the key demand and supply-side factors affecting the current low price of milk?
  5. Consider the market for (a) milk and (b) wheat. What are (if any) the market failures within each area?
  6. Agriculture is an area where we do see significant government intervention. Should the UK government be doing more to help the UK’s dairy farmers? If so, what should they do and would this intervention create further problems, e.g. unintended consequences?

An above-inflation rise in the NMW

In the blog Effects of raising the minimum
wage, the policy of an above-inflation rise in the minimum wage was discussed, as this had been advocated by political leaders. Over the past 5 years, the minimum wage has fallen in real terms, but from October 2014, the national minimum wage will increase 19p per hour and this rise will be the first time since 2008 when the increase will be higher than inflation.

The National Minimum Wage is a rate applied to most workers in the UK and is their minimum hourly entitlement. For adults over the age of 21, it will be increased by just over 3% to £6.50. Rises will also occur for 18-20 year olds, though their increase will be lower at 10p and will take the hourly wage to £5.13 an hour, representing a 2% rise. Those aged 16 and 17 will also see a 2% rise, taking their wage up by 7p to £3.79. With inflation currently at 1.9% (as measured by the CPI), these rises outstrip inflation, representing a real increase in the minimum wage. Undoubtedly this is good news for workers receiving the minimum wage, and it is thought that millions of workers will benefit.

Vince Cable said:

The recommendations I have accepted today mean that low-paid workers will enjoy the biggest cash increase in their take home pay since 2008…This will benefit over one million workers on national minimum wage and marks the start of a welcome new phase in minimum wage policy.

While this rise has been praised, there are still suggestions that this minimum wage is too low and does not represent a ‘living wage’. The General Secretary of Unison said:

Across the country people are struggling to make ends meet. The sooner we move to a Living Wage the better. The real winners today will again be payday loan sharks who prey on working people, unable to bridge the financial gap between what they earn and what their families need to survive.


(Click here for a PowerPoint of the above chart.)

The Chancellor eventually wants to increase the minimum wage to £7 per hour, but there will undoubtedly be an impact on businesses of such a rise. Is it also possible that with the national minimum wage being pushed up, unemployment may become a problem once more?

Market wages are determined by the interaction of the demand and supply of labour and when they are in equilibrium, the only unemployment in the economy will be equilibrium unemployment, namely frictional or structural. However, when the wage rate is forced above the equilibrium wage rate, disequilibrium unemployment may develop. At a wage above the equilibrium the supply of labour will exceed the demand for labour and the excess is unemployment.

By increasing the national minimum wage, firms will face higher labour costs and this may discourage them from taking on new workers, but may also force them into laying off existing workers. The impact of the minimum wage on unemployment doesn’t seem to be as pronounced as labour market models suggest, so perhaps the increase in the minimum wage will help the lowest paid families and we won’t observe any adverse effect on businesses and employment. The following articles consider this story.

Private versus public

Many people are attracted to work in the private sector, with expectations of greater opportunities for promotion, more variation in work and higher salaries. However, according to the Office for National Statistics, it may be that the oft-talked-of pay differential is actually in the opposite direction. Data from the ONS suggests that public sector workers are paid 14.5% more on average than those working in the private sector.

As is the case with the price of a good, the price of labour (that is, the wage rate) is determined by the forces of demand and supply. Many factors influence the wages that individuals are paid and traditional theory leads us to expect higher wages in sectors where there are many firms competing for labour. With the government acting as a monopsony employer, it has the power to force down wages below what we would expect to see in a perfectly competitive labour market. However, the ONS data suggests the opposite. What factors can explain this wage differential?

Jobs in the public sector, on average, require a higher degree of skills. There tend to be entry qualifications, such as possessing a university degree. While this is the case for many private-sector jobs as well, on average it is a greater requirement in the public sector. The skills required therefore help to push up the wages that public-sector workers can demand. Another explanation could be the size of public-sector employers, which allows them to offer higher wages. When the skills, location, job specifications etc. were taken into account, the 14.5% average hourly earnings differential declined to between just 2.2% and 3.1%, still in favour of public-sector workers. It then reversed to give private-sector workers the pay edge, once the size of the employer was taken out.

Further analysis of the data also showed that, while it may pay to be in the public sector when you’re starting out on your career, it pays to be in the private sector as you move up the career ladder. Workers in the bottom 5% of earners will do better in the public sector, while those in the top 5% of earners benefit from private-sector employment. The ONS said:

Looking at the top 5%, in the public sector earnings are greater than £31.49 per hour, while in the private sector, the top 5% earn more than £33.63 per hour… The top 1% of earners in the private sector, at more than £60.21 per hour, earns considerably more than the top 1% of earners in the public sector, at more than £49.65 per hour.

The data from the ONS thus suggest a reversal in the trend of average public-sector pay being higher than private sector pay, once all the relevant factors are taken into account.

This will naturally add to debates about living standards, which are likely to take on a stronger political slant as the next election approaches. It is obviously partly down to the public-sector pay freeze that we saw in 2010 and also to a reversal, at least in part, of the previous trend from 2008, where public-sector pay had been growing faster than private-sector pay. However, depending on the paper you read or the person you listen to, they will offer very different views as to who gets paid more. All you need to do in this case is look at the titles of the newspaper articles written by the Independent and The Telegraph! Whatever the explanation, these new data provide a wealth of information about relative prospects for pay for everyone.

Effects of raising the minimum wage

Conservative Party leaders are considering the benefits of an above-inflation rise in the minimum wage. This policy has been advocated by both the Labour Party and the Liberal Democrats as a means of helping the lowest paid workers. From 2008 to 2013, minimum wage rates fell 5.2% in real terms: in other words, nominal increases were less than the increase in both the RPI and CPI (see UK minimum wage: a history in numbers).

Advocates of a real rise in the minimum wage argue that not only would it help low-paid workers, many of whom are in severe financial difficulties, but it would benefit the Treasury. According to Policy Exchange, a free-market think tank closely aligned to the Conservative Party, increasing the minimum wage by 50p would save the Government an estimated £750m a year through higher tax revenues and lower benefit payments.

But even such a rise to £6.81 would still leave the minimum wage substantially below the living wage of £8.80 in London and £7.65 in the rest of the UK, as estimated by the Living Wage Foundation (see The cost of a living wage). Although many businesses are now paying at least the living wage, many others, especially small businesses, argue that a rise in the minimum wage above the rate of inflation would force them to consider cutting the number of employees or reducing hours for part-time workers.

Meanwhile, in the USA 13 states have raised their minimum wage rates from the 1st January 2014 (see). Some of the rises, however, were tiny: as little as 15 cents. In a couple of cases, the rise is $1. Currently 21 states and DC have minimum wage rates above the Federal level of $7.25 (approx. £4.40); 20 states have rates the same as the Federal level; 4 states have rates below the Federal level. At $9.32 per hour, Washington State has the highest state minimum wage; the lowest rates ($5.15) are in Georgia and Wyoming. In 5 states there is no minimum wage at all. As the ABC article below states:

The piecemeal increases at the local level are occurring amidst a national debate over low wages and income inequality. Fast food and retail workers have been staging protests and walking off work for more than a year, calling for better pay and more hours. Currently, fast food workers nationally earn an average of about $9 per hour.

Workers from McDonald’s, Wendy’s, Burger King and other fast food joints are calling for $15 per hour. Wal-Mart workers organizing as part of the union-backed OUR Walmart aren’t asking for a specific dollar amount increase, but they say it’s impossible to live on the wages they currently receive.

President Obama has been throwing his weight behind the issue. Earlier this month, the President said in a speech that it’s “well past the time to raise the minimum wage that in real terms right now is below where it was when Harry Truman was in office.” But such legislation has a bleaker outlook if it reaches the Republican-led House of Representatives. House Speaker John Boehner has said that raising the minimum wage leads to a pullback in hiring.

So what are the costs and benefits of a significant real rise is the minimum wage on either side of the Atlantic? The articles explore the issues.
