Minimum pricing for alcohol

The debate about a minimum price for alcohol continues to be prompted by concerns over high levels of drinking, its effect on public health and public order, and a widespread belief that most of the alcohol that contributes to drunken behaviour is irresponsibly priced and sold. Minimum pricing for alcohol, although considered a radical intervention, is not a new policy. A minimum unit price (MUP) for alcohol was introduced in Scotland in 2018, in Wales in 2020, in the Republic of Ireland in 2022 and looks likely to be introduced in Northern Ireland.

Despite more countries following Scotland’s lead, there are no current plans to consider an application of an MUP in England. However, with recent increases in the MUP in Scotland and the findings of a five-year review in Wales, it would suggest that this policy will continue to be at the forefront of discussions of how to tackle impacts of alcohol consumption.

Reasons and options for intervention

The main goal of introducing a minimum unit price for alcohol is to tackle unwanted consequences from the consumption of alcohol. While many people consume alcoholic drinks safely without any problems, some patterns of alcohol use are associated with significant physical, mental and social harm.

It costs UK society more than £27 billion a year through a combination of health, crime, workplace and social welfare costs. Therefore, some governments in the British Isles have deemed it necessary to intervene in this market to reduce alcohol-related harm and protect the health of those regularly drinking more than the recommended 14 units per week.

Research has shown that making alcohol less affordable can reduce consumption and hence related harms. The World Health Organization considers minimum pricing one of its ‘best buys’ for tackling harmful alcohol use.

There are three main policy options that aim to reduce the consumption of alcohol by making alcohol less affordable. One is to tax alcoholic drinks; the second is to set a minimum price per unit of alcohol; the third is to ban the sale of alcohol drinks below cost price (the level of alcohol duty plus VAT).

The policy option of an MUP has been adopted by Scotland, Wales and the Republic of Ireland; England has opted to use a ban on selling alcohol below the level of alcohol duty plus VAT (since 28 May 2014).

What is a minimum price?

The introduction by the government of a minimum price for a product means that it cannot legally be sold below that price. It can be set in order to achieve certain economic or social objectives that are not currently being achieved at equilibrium in the market. In order for the policy to have an effect, the minimum price must be set above the equilibrium price. This price floor then prevents prices from falling too low and settling back at equilibrium below the MUP.

A common misconception is that introducing a minimum price for alcohol is a form of taxation. However, this is not the case. Implementing an MUP means that any extra money from higher prices goes to the retailers and producers, not to the government.

Why choose a minimum price floor?

The policy has two main objectives. The first is to protect the interests of drinkers who may make poor decisions on their own behalf. This may be from lack of information, social pressures or a disregard for their own long-term health or welfare.

The second objective is to reduce the external costs placed on health services, the police, the criminal justice system, on fellow citizens or employers. There are also longer-term external costs when alcohol abuse impacts on productivity or leads to repeated absences from work.

It is argued that MUP intervention can encourage positive changes in behaviour of both consumers and producers. It can target harmful excessive drinking, while leaving the more moderate drinker relatively unaffected.

A positive impact on consumers is the possible changes in demand. People who previously consumed cheap, and often strong, drinks, such as cheap cider, will find that their marginal private cost of consuming alcohol has increased. Depending on the price elasticity of demand, their consumption will decrease and there will be a reduction in alcohol-related violence and other external costs. A positive impact on producers is that it can encourage drinks manufacturers themselves to reduce the alcohol content of their products and, therefore, limit any increase in price passed on to the consumer.

How it differs in the different parts of the British Isles

While minimum alcohol pricing is in place in several countries, policies differ. In terms of the British Isles, in 2018 Scotland became the first country to introduce a national minimum price for all types of alcohol. Two years later, Wales followed suit. The Republic of Ireland introduced minimum pricing in January 2022, while Northern Ireland has been engaged in consultation on the policy for several years. The following table shows when MUP was introduced and at what rates.

Has the MUP been effective?

Wales has reached the five-year review point since the MUP was introduced. Many of the findings within the Welsh evaluation have strong resonance with those elsewhere, particularly those of the final Scottish evaluation. There have been five main findings:

  • Implementation has been smooth. Retailers have largely complied with the law, and enforcement has been effective.
  • Certain cheap alcohol products have disappeared. Large bottles of strong cider, for example, are now rare. There have also been shifts in promotions and product availability.
  • There are indications that overall alcohol consumption in Wales has declined. While it is difficult to measure directly, purchasing data suggests a reduction.
  • Concerns about unintended consequences have not materialised significantly. Predictions of a rise in home brewing, substance switching, shoplifting and cross-border purchasing have not been widely observed.
  • Some drinkers have changed their purchasing habits. A minority have switched from cider to wine or spirits as price differences narrowed. Others, particularly those on low incomes, experienced further struggles in financially maintaining their drinking habits.

There was also a study published last year (2024) in the journal Economic Inquiry, looking at the impacts of the policy during lockdown restrictions. The study showed that the introduction of MUP in Wales resulted in a 15% increase in transaction prices and a sharp reduction in the amount of alcohol bought, around 20%, with an overall drop in expenditure per customer compared to England over the same period.

However, it should be noted that the COVID pandemic disrupted drinking habits and the availability of alcohol. In addition, evaluating the overall effects of the policy has been complex with other economic factors, including the cost-of-living crisis, also influencing affordability.

Is it a fair policy?

A counter argument to applying a price intervention on alcohol is that it may have unintended private and external costs. One argument claims that young people could decide to switch to cheaper non-alcoholic drugs instead. Alternatively, they may seek to purchase alcohol on illegal shadow markets.

Critics of the policy argue that it negatively impacts those who consume alcohol responsibly, especially families on average or below-average incomes. The wine and spirits industry tried to lobby against the Scottish government, arguing that it is inconsistent with the operation of the free market and that the intervention creates a barrier to trade. They claim that lower sales of alcoholic drinks will cost jobs in the UK, both in manufacturing and from reduced revenues of corner shops, pubs and other retailers.

There is also an argument that relying solely on an MUP targets the affordability of drinking rather than addressing all aspects of alcohol harm. Therefore, this policy is not necessarily effective in achieving all the government’s goals. Critics argue that this policy should be one component of a more comprehensive strategy delivery, which might include education, restricting the availability of alcohol, banning advertising, increasing alcohol duty, etc.

Conclusion

Although there are currently no plans to implement an MUP in England, there is ongoing pressure for the Government to consider adopting one. In the Autumn of 2024, Lord Darzi carried out an independent investigation of the NHS in England. This investigation into the NHS highlighted the ‘alarming’ death toll in England caused by cheap drink (see link below). This led public health leaders to call for action to increase the price of cheap alcohol in supermarkets and off-licences.

However, the policy itself is not without its critics, especially those citing continued trends in actual numbers of alcohol-related deaths. Therefore, it is suggested that the policy needs to be accompanied by well-funded treatment and support services for people experiencing alcohol-related difficulties. If combined with other policy measures and social support, it has the potential to contribute significantly to reductions in alcohol-related harm.

Despite reservations, overall a minimum price per unit of alcohol is viewed by many as a justified intervention and is well supported by evidence. It has been accepted that a minimum price is required to reduce consumption closer towards the social optimum and in order to bring about change in consumer and producer behaviour. Given the evidence provided from current MUP countries and ongoing discussions of alcohol-related deaths in England, health officials believe a review is almost certain, even though the current government reportedly ruled out minimum unit pricing shortly after winning power.

Why are Tesla sales plummeting?

Tesla sales have fallen dramatically recently. In Europe they were down 47.7% in January 2025 compared with January 2024. In Spain the figure was 75.4%, in France 63.4%, in Germany 59.5%, in Sweden 44.3%, in Norway 37.9%, in the UK 18.2% and in Italy 13.4%. And it was not just Europe. In Australia the figure was 33.2%, in China 15.5% and in California 11.6%. Meanwhile, Tesla’s share price has fallen from a peak of $480 on 17 December 2024 to $338 on 21 February 2025, although that compares with $192 in February 2024.

So why have Tesla sales fallen? It’s not because of a rise in price (a movement up the demand curve); indeed, Tesla cut its prices in 2024. Part of the reason is on the supply side. In several countries, stocks of Teslas are low. Some consumers who would have bought have had to wait. However, the main reason is that the demand curve has shifted to the left. So why has this happened?

A reaction to Elon Musk?

One explanation is a growing unpopularity of Elon Musk among many potential purchasers of electric vehicles (EVs). People are more likely to buy an EV if they are environmentally concerned and thus more likely to be Green voters or on the political left and centre. Elon Musk, by supporting Donald Trump and now a major player in the Trump administration, is seen as having a very different perspective. Trump’s mantra of ‘drill, baby drill’ and his announced withdrawal from the Paris agreement and the interventions of Trump, Vance and Musk in European politics have alienated many potential purchasers of new Teslas. Elon Musk has been a vocal supporter of the right-wing Alternative for Germany (AfD) party, describing the party as the ‘last spark of hope for this country’ (see BBC article linked below).

There has been outspoken criticism of Musk in the media and the Financial Times reports existing owners of Teslas, who are keen to distance themselves from Musk, ordering stickers for their cars which read ‘I bought this before Elon went crazy’. In a survey by Electrifying.com, 59% of UK potential EV buyers stated that Musk’s reputation put them off buying a Tesla.

Other reasons for a leftward shift in the demand for Teslas

But is it just the ‘Musk factor’ that has caused a fall in demand? It is useful to look at the general determinants of demand and see how each might have affected the demand for Teslas.

The price, number, quality and availability of substitutes  Tesla faces competition, not only from long-established car companies, such as Ford, VW, Volvo/Polestar, Seat/Cupra and Toyota, moving into the EV market, but also from Chinese companies, such as BYD and NIO. These are competing in all segments of the EV market and competition is constantly increasing. Some of these companies are competing strongly with Tesla in terms of price; others in terms of quality, style and imaginative features. The sheer number of competitor models has grown rapidly. For some consumers, Teslas now seem dated compared with competitors.

The price and availability of complements.  The most relevant complement here is electrical charging points. As Teslas can be charged using both Tesla and non-Tesla charging points, there is no problem of compatibility. The main issue is the general one for all EVs and that is how to achieve range conveniently. The fewer the charging points and more widely disbursed they are, the more people will be put off buying an EV, especially if they are not able to have a charging point at home. Clearly, the greater the range of a model (i.e. the distance that can be travelled on a full battery), the less the problem. Teslas have a relatively high range compared with most (but not all) other makes and so this is unlikely to account for the recent fall in demand, especially relative to other makes.

Expectations.  The current best-selling Tesla EV is the Model Y. This model is being relaunched in a very different version, as are other Tesla models. Consumers may prefer to wait until the new models become available. In the meantime, demand would be expected to fall.

Conclusions

As we have seen, there have been a number of factors adversely affecting Tesla sales. Growing competition is a major factor. Nevertheless, the increasing gap politically between Elon Musk and many EV consumers is a major factor – a factor that is likely to grow in significance if Musk’s role in the Trump administration continues to be one of hostility towards the liberal establishment and in favour of the hard right.

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.

Crude oil – a volatile market

The market for crude oil is usually a volatile one. Indeed, in the last few months, the market has seen prices rise and fall due to various supply and demand influences. Crude oil is coined the ‘King of Commodities’ due to the impact it has on consumers, producers and both the micro and macro economy. The price of crude oil affects everything from the cost of producing plastics, transportation, and food at the supermarket.

This makes the market for crude oil an economic powerhouse which is closely watched by businesses, traders, and governments. To gain a full understanding of the movements in this market, it is important to identify how demand and supply affect the price of crude oil.

What influences the demand and supply of crude oil?

The law of demand and supply states that if demand increases, prices will rise, and if supply increases, prices will fall. This is exactly what happens in the market for crude oil. The consumer side of the market consists of various companies and hundreds of millions of people. The producer side of the market is made up of oil-producing countries. Collectively, both consumers and producers influence the market price.

However, the demand and supply of crude oil, and therefore the price, is also affected by global economic conditions and geopolitical tensions. What happens in the world impacts the price of oil, especially since a large proportion of the world’s biggest oil producers are in politically unstable areas.

Over the past five years, global events have had a major impact on the price of oil. The economic conditions created by the impact of the COVID pandemic saw prices plummet from around $55 per barrel just before the pandemic in February 2020 to around $15 per barrel in April 2020. By mid-2021 they had recovered to around $75 per barrel. Then, in the aftermath of Russia’s invasion of Ukraine in February 2022, the price surged to reach $133 in June 2022. More recently, geopolitical tensions in the Middle East and concerns about China’s economic outlook have intensified concerns about the future direction of the market. (Click here for a PowerPoint of the chart.)

Geopolitical tensions

In the first week of October 2024, the price of crude oil rose by almost 10% to around $78 per barrel as the conflict in the Middle East intensified. It unfortunately comes at a time when many countries are starting to recover from the rise in oil prices caused by the pandemic and the war in Ukraine. Any increase in prices will affect the price that consumers pay to fill up their vehicles with fuel, just when prices of diesel and petrol had reached their lowest level for three years.

The Governor of the Bank of England, Andrew Bailey, has said that the Bank is monitoring developments in the Middle East ‘extremely closely’, as the conflict has the potential to have serious impacts in the UK. The Bank of England will therefore be watching for any movement in oil prices that could fuel inflation.

The main concerns stem from further escalation in the conflict between Israel and the Iran-backed armed group, Hezbollah, in Lebanon. If Israel decides to attack Iran’s oil sector, this is likely to cause a sharp rise in the price of oil. Iran is the world’s seventh largest oil exporter and exports over half of its production to China. If the oilfields of a medium-sized supplier, like Iran, were attacked, this could threaten general inflation in the UK, which could in turn influence any decision by the Bank of England to lower interest rates next month.

Supply deficits

This week (2nd week of October 2024) saw the price of crude oil surge above $81 per barrel to hit its highest level since August. This rise means that prices increased by 12% in a week. However, this surge in price also means that prices rose by almost 21% between the start September and the start of October alone. Yet it was only in early September when crude oil hit a year-to-date low, highlighting the volatility in the market.

As the Middle-East war enters a new and more energy-related phase, the loss of Iranian oil would leave the market in a supply deficit. The law of supply implies that such a deficit would lead to an increase in prices. This also comes at a time when the US Strategic Petroleum Reserve has also been depleted, causing further concerns about global oil supply.

However, the biggest and most significant impact would be a disruption to flows through the Strait of Hormuz. This is a relatively narrow channel at the east end of the Persian Gulf through which a huge amount of oil tanker traffic passes – about a third of total seaborne-traded oil. It is therefore known as the world’s most important oil transit chokepoint. The risk that escalation could block the Strait of Hormuz could technically see a halt in about a fifth of the world’s oil supply. This would include exports from big Gulf producers, including Saudi Arabia, UAE, Kuwait and Iraq. In a worst-case scenario of a full closure of the Strait, a barrel of oil could very quickly rise to well above $100.

Disruption to shipments would also lead to higher gas prices and therefore lead to a rise in household gas and electricity bills. As with oil, gas prices filter down supply chains, affecting the cost of virtually all goods, resulting in a further rise in the cost of living. With energy bills in the UK having already risen by 10% for this winter, an escalation to the conflict could see prices rise further still.

China’s economic outlook


Despite the concern for the future supply of oil, there is also a need to consider how the demand for oil could impact price changes in the market. The price of oil declined on 14 October 2024 in light of concerns over China’s struggling economy. As China is the world’s largest importer of crude oil, there are emerging fears about the potential limits on fuel demand. This fall in price reversed increases made the previous week as investors become concerned about worsening deflationary pressures in China.

Any reduced demand from China could indicate an oversupply of crude oil and therefore potential price declines. Official data from China reveal a sharp year-on-year drop in the producer price index of 2.8% – the fastest decline in six months. These disappointing results have stirred uncertainty about the Chinese government’s economic stimulus plans. Prices could fall further if there are continuing doubts about the government’s ability to implement effective fiscal measures to promote consumer spending and, in turn, economic growth.

As a result of the 2% price fall in oil prices on 14 October, OPEC (the Organization of the Petroleum Exporting Countries) has lowered its 2024 and 2025 global oil demand growth. This negative news outweighed market concerns over the possibility that an Israeli response to Iran’s missile attack could disrupt oil production.

What is the future for oil prices?

It is expected that the market for oil will remain a volatile one. Indeed, the current uncertainties around the globe only highlight this. It is never a simple task to predict what will happen in a market that is influenced by so many global factors, and the current global landscape only adds to the complexity.

There’s a wide spectrum of predictions about what could come next in the market for crude oil. Given the changes in the first two weeks of October alone, supply and demand factors from separate parts of the globe have made the future of oil prices particularly uncertain. Callum Macpherson, head of commodities at Investec, stated in early October that ‘there is really no way of telling where we will be this time next week’ (see the first BBC News article linked below).

Despite the predominately negative outlook, this is all based on potential scenarios. Caroline Bain, chief commodities economist at Capital Economics suggests that if the ‘worst-case scenario’ of further escalation in the Middle East conflict does not materialise, oil prices are likely to ‘ease back quite quickly’. Even if Iran’s supplies were disrupted, China could turn to Russia for its oil. Bain says that there is ‘more than enough capacity’ globally to cover the gap if Iranian production is lost. However, this does then raise the question of where the loyalty of Saudi Arabia, the world’s second largest oil producer, lies and whether it will increase or restrict further production.

What is certain is that the market for crude oil will continue to be a market that is closely observed. It doesn’t take much change in global activity for prices to move. Therefore, in the current political and macroeconomic environment, the coming weeks and months will be critical in determining oil prices and, in turn, their economic effects.

Should train companies scrap peak-time fares?

In many countries, train fares at peak times are higher than at off-peak times. This is an example of third-degree price discrimination. Assuming that peak-time travellers generally have a lower price elasticity of demand, the policy allows train companies to increase revenue and profit.

If the sole purpose of ticket sales were to maximise profits, the policy would make sense. Assuming that higher peak-time fares were carefully set, although the number travelling would be somewhat reduced, this would be more than compensated for by the higher revenue per passenger.

But there are external benefits from train travel. Compared with travel by car, there are lower carbon emissions per person travelling. Also, train travel helps to reduce road congestion. To the extent that higher peak-time fares encourage people to travel by car instead, there will be resulting environmental and congestion externalities.

The Scottish experiment with abolishing higher peak-time fares

In October 2023, the Scottish government introduced a pilot scheme abolishing peak-time fares, so that tickets were the same price at any time of the day. The idea was to encourage people, especially commuters, to adopt more sustainable means of transport. Although the price elasticity of demand for commuting is very low, the hope was that the cross-price elasticity between cars and trains would be sufficiently high to encourage many people to switch from driving to taking the train.

One concern with scrapping peak-time fares is that trains would not have the capacity to cope with the extra passengers. Indeed, one of the arguments for higher peak-time fares is to smooth out the flow of passengers during the day, encouraging those with flexibility of when to travel to use the cheaper and less crowded off-peak trains.

This may well apply to certain parts of the UK, but in the case of Scotland it was felt that there would be the capacity to cope with the extra demand at peak time. Also, in a post-COVID world, with more people working flexibly, there was less need for many people to travel at peak times than previously.

Reinstatement of peak-time fares in Scotland

It was with some dismay, therefore, especially by commuters and environmentalists, when the Scottish government decided to end the pilot at the beginning of October 2024 and reinstate peak-time fares – in many cases at nearly double the off-peak rates. For example, the return fare between Glasgow and Edinburgh rose from £16.20 to £31.40 at peak times.

The Scottish government justified the decision by claiming that passenger numbers had risen by only 6.8%, when, to be self-financing, an increase of 10% would have been required. But this begs the question of whether it was necessary to be self-financing when the justification was partly environmental. Also, the 6.8% figure is based on a number of assumptions that could be challenged (see The Conversation article linked below). A longer pilot would have helped to clarify demand.

Other schemes

A number of countries have introduced schemes to encourage greater use of the railways or other forms of public transport. One of these is the flat fare for local journeys. Provided that this is lower than previously, it can encourage people to use public transport and leave their car at home. Also, its simplicity is also likely to be attractive to passengers. For example, in England bus fares are capped at £2. Currently, the scheme is set to run until 31 December 2024.

Another scheme is the subscription model, whereby people pay a flat fee per month (or week or year, or other time period) for train or bus travel or both. Germany, for example, has a flat-rate €49 per month ‘Deutschland-Ticket‘ (rising to €58 per month in January 2025). This ticket provides unlimited access to local and regional public transport in Germany, including trains, buses, trams, metros and ferries (but not long-distance trains). This zero marginal fare cost of a journey encourages passengers to use public transport. The only marginal costs they will face will be ancillary costs, such as getting to and from the train station or bus stop and having to travel at a specific time.
