The UK’s poor record on productivity since the 2008 financial crisis is well documented, not least in this blog series. Output per worker has flatlined over the 17 years since the crisis. As was noted in the blog, The UK’s poor productivity record, low UK productivity is caused by a number of factors, including the lack of investment in training, the poor motivation of many workers and the feeling of being overworked, short-termism among politicians and management, and generally poor management practices.
One of the most significant issues identified by analysts and commentators is the lack of investment in physical capital, both by private companies and by the government in infrastructure. Gross fixed capital formation (a measure of investment) has been much lower in the UK compared to international competitors.
From Figure 1 it can be observed that, since the mid-1990s, the UK has consistently had lower investment as a percentage of GDP compared to other significant developed market economies. The cumulative effect of this gap has contributed to lower productivity and lower economic growth.
Interestingly, since the financial crisis, UK firms have had high profitability and associated high cash holdings. This suggests that firms have had a lot of financial resources to reinvest. However, data from the OECD suggests that reinvestment rates in the UK, typically 40–50% of profit, are much lower than in many other OECD countries. In the USA the rate is 50%, in Germany 60–70% and in Japan 70%+. There is much greater emphasis in the UK on returning funds to shareholders through dividends and share buybacks. However, the reinvestment of much of this cash within firms could have gone some way to addressing the UK’s investment gap – but, it hasn’t been done.
Analysis by the OECD suggest that, while the cost of financing investment has declined since the financial crisis, the gap between this and the hurdle rate used to appraise investments has widened. Between 2010 and 2021 the difference nearly doubled to 4%. This increase in the hurdle rate can be related to increases in the expected rate of return by UK companies and their investors.
In this blog we will analyse (re)investment decisions by firms, discussing how increases in the expected rate of return in the UK raise the hurdle rate used to appraise investments. This reduces the incentive to engage in long-term investment. We also discuss policy prescriptions to improve reinvestment rates in the UK.
Investment and the expected rate of return
Investment involves the commitment of funds today to reap rewards in the future. This includes spending on tangible and intangible resources to improve the productive capacity of firms. Firms must decide whether the commitment of funds is worthwhile. To do so, economic theory suggests that they need to consider the compensation required by their provider of finance – namely, investors.
What rewards do investors require to keep their funds invested with the firm?
When conducting investment appraisal, firms compare the estimated rate of return from an investment with the minimum return investors are prepared to receive (termed the ‘expected return’). Normally this is expressed as a percentage of the initial outlay. Firms have to offer returns to investors which are equal to or greater than the minimum expected return – the return that is sufficient to keep funds invested in the firm. Therefore, returns above this minimum expected level are termed ‘excess returns’.
When firms conduct appraisals of potential investments, be it in tangible or intangible capital, they need to take into account the fact that net benefits, expressed as cash flows, will accrue over the life of the investment, not all at once. To do this, they use discounted cash flow (DCF) analysis. This converts future values of the net benefits to their present value. This is expressed as follows:
Where:
NPV = Net present value (discounted net cash flows);
K = Capital outlay (incurred at the present time);
C = Net cash flows (occur through the life of the investment project);
r = Minimum expected rate of return.
In this scenario, the investment involves an initial cash outlay (K), followed in subsequent periods by net cash inflows each period over the life of the investment, which in this case is 25 years. All the cash flows are discounted back to the present so that they can be compared at the same point in time.
The discount rate (r) used in appraisals to determine the present value of net cash flows is determined by the minimum expected return demanded by investors. If at that hurdle rate there are positive net cash flows (+NPV), the investment is worthwhile and should be pursued. Conversely, if at that hurdle rate there are negative net cash flows (–NPV), the investment is not worthwhile and should not be pursued.
According to economic theory, if a firm cannot find any investment projects that produce a positive NPV, and therefore satisfy the minimum expected return, it should return funds to shareholders through dividends or share buybacks so that they can invest the finance more productively.
Firm-level data from the OECD suggest that UK firms have had higher profits and this has been associated with increased cash holdings. But, due to the higher hurdle rate, less investment is perceived to be viable and thus firms distribute more of their profits through dividends and share buybacks. These payouts represent lost potential investment and cumulatively produce a significant dent in the potential output of the UK economy.
Why are expected rates of return higher in the UK?
This higher minimum rate of expected return can be explained by factors influencing its determinants; opportunity cost and risk/uncertainty.
Higher opportunity cost. Opportunity cost relates to the rate of return offered by alternatives. Investors and, by implication firms, will have to consider the rate of return offered by alternative investment opportunities. Typically, investors have focused on interest rates as a measure of opportunity cost. Higher interest rates raise the opportunity cost of an investment and increase the minimum expected rate of return (and vice versa with lower interest rates).
However, it is not interest rates that have increased the opportunity cost, and hence the minimum expected rate of return associated with investment, in the UK since the financial crisis. For most of the period since 2008, interest rates have been extremely low, sitting at below 1%, only rising significantly during the post-pandemic inflationary surge in 2022. This indicates that this source of opportunity cost for the commitment of business investment has been extremely low.
However, there may be alternative sources of opportunity cost which are pushing up the expected rate of return. UK investors are not restricted to investing in the UK and can move their funds between international markets determined by the rate of return offered. The following table illustrates the returns (in terms of percentage stock market index gain) from investing in a sample of UK, US, French and German stock markets between August 2010 and August 2025.
When expressed in sterling, returns offered by UK-listed companies are lower across the whole period and in most of the five-yearly sub-periods. Indeed, the annual equivalent rate of return (AER) for the FTSE 100 index across the whole period is less than half that of the S&P 500. The index offered a paltry annual return of 2.57% between 2015 and 2020, while the US index offered a return of 16.48%. Both the French and German indices offered higher rates of return, in the latter part of the period particularly. This represents a higher opportunity cost for UK investors and may have increased their expectations about the return they require for UK investments.
Greater perceived risk/uncertainty. Expected rates of return are also determined by perceptions of risk and uncertainty – the compensation investors need to bear the perceived risk associated with an investment. Investors are risk averse. They demand higher expected return as compensation for higher perceived risk. Higher levels of risk aversion increase the expected rate of return and related investment hurdle rates.
There has been much discussion of increased uncertainty and risk aversion among global investors and firms (see the blogs Rising global uncertainty and its effects, World Uncertainty Index, The Chancellor’s fiscal dilemma and Investment set to fall as business is baffled by Trump). The COVID-19 pandemic, inflation shocks, the war in Ukraine, events across the Middle East and the trade policies adopted by the USA in 2025 have combined to produce a very uncertain business environment.
While these have been relatively recent factors influencing world-wide business uncertainty, perceptions of risk and uncertainty concerning the UK economy seem to be longer established. To measure policy-related economic uncertainty in the UK, Baker, Bloom and Davis at www.PolicyUncertainty.com construct an index based on the content analysis of newspaper articles mentioning terms reflecting policy uncertainty.
Figure 2 illustrates the monthly index from 1998 to July 2025. The series is normalised to standard deviation 1 prior to 2011 and then summed across papers, by month. Then, the series is normalised to mean 100 prior to 2011.
Some of the notable spikes in uncertainty in the UK since 2008 have been labelled. Beginning with the global financial crisis, investors and firms became much more uncertain. This was exacerbated by a series of economic shocks that hit the economy, one of which, the narrow vote to leave the European Union in 2016, was specific to the UK. This led to political turmoil and protracted negotiations over the terms of the trade deal after the UK left. This uncertainty has been exacerbated recently by the series of global shocks highlighted above and also the budget uncertainty of Liz Truss’s short-lived premiership and now the growing pressure to reduce government borrowing.
While spikes in uncertainty occurred before the financial crises, the average level of uncertainty, as measured by the index, has been much higher since the crisis. From 1998 to 2008, the average value was 89. Since 2008, the average value has been 163. Since the Brexit vote, the average value has been 185. This indicates a much higher perception of risk and uncertainty over the past 15 year and this translates into higher minimum expected return as compensation. Consequently, this makes many long-term investment projects less viable because of higher hurdle rates. This produces less productive investment in capital, contributing significantly to lower productivity.
Policy proposals
There has been much debate in the UK about promoting greater long-term investment. Reforms have been proposed to improve public participation in long-term investment through the stock market. To boost investment, this would require the investing public to be prepared to accept lower expected returns for a given level of risk or accept higher risk for a given level of returns.
Evidence suggests that the appetite for this may be very low. UK savers tend to favour less risky and more liquid cash deposits. It may be difficult to encourage them to accept higher levels of risk. In any case, even if they did, many may invest outside the UK where the risk-return trade-off is more favourable.
Over the past 10 years, policy uncertainty has played a significant role in deterring investment. So, if there is greater continuity, this may then promote higher levels of investment.
The Labour government has proposed policies which aim to share or reduce the risk/uncertainty around long-term investment for UK businesses. For instance, a National Wealth Fund (NWF) has been established to finance strategic investment in areas such as clean energy, gigafactories and carbon capture. Unfortunately, the Fund is financed by borrowing through financial markets and the amount expected to be committed over the life of the current Parliament is only £29 billion, assuming that private capital matches public commitments in the ratio expected. It is questionable whether the Fund’s commitment will be sufficient to attract private capital.
Alternatively, Invest 2035 is a proposal to create a stable, long-term policy environment for business investment. It aims to establish an Industrial Strategy Council for policy continuity and to tackle issues like improving infrastructure, reducing energy costs and addressing skills gaps. Unfortunately, even if there is some attempt at domestic policy stability, the benefits may be more than offset by perceptions around global uncertainty, which may mean that UK investors’ minimum expected rates of return remain high and long-term investment low for the foreseeable future.

HS2 has been cancelled north of Birmingham. The prime minister, Rishi Sunak, announced this at the Conservative Party conference on 4 October, some 13 years after the plan was adopted by the Labour government to build a new high-speed railway from London to Birmingham, which then would branch into two legs – one to Manchester and one to Leeds. The initial budget for this was £15.8bn to £17.4bn. When it came to power, the Conservative-Liberal coalition government ordered a review of the plan. In light of this, the government gave the green light in January 2012 for the full Y-shaped project to go ahead. The London–Birmingham leg was planned to open in 2026 and the two northern legs from 2033.
The project was divided into two phases: Phase 1 to Birmingham and Phase 2 to Manchester and Leeds. The Phase 1 parliamentary bill became law in February 2017 and soon after that, various construction contracts were signed. After some delays, preparation for construction work began in June 2019. There was growing doubt, however, about the viability of the northern legs.
On becoming prime minister in 2019, Boris Johnson ordered an independent review of the project after estimates that the costs of the full project would be some £88bn. The review, chaired by Douglas Oakervee, was published in December 2019 (for a link, see list of reports below). It found that costs (in 2015 prices) were likely to be between £62bn and £69bn. Nevertheless, it concluded that the project should proceed: that the original rationale for HS2 still held; that there were:
no shovel-ready alternative investments in the existing network that were available: if HS2 were to be cancelled, many years of planning work would be required to identify, design and develop new proposals; that the upgrading of existing lines would also come at a high passenger cost with significant disruption; that there would be serious consequences for the supply chain, the fragile UK construction industry and confidence in UK infrastructure planning if HS2 were to be cancelled at this late stage.
In February 2020, the prime minister announced that HS2 would go ahead, including the legs to Manchester and Leeds. The Department for Transport published a document (see source line to the following table) giving the full business case for Phase 1 and the outline case for Phase 2. The document itemised the costs and benefits as estimated at the time.
Source: Full Business Case: High Speed Two, Table 2.9, Department for Transport (April 2020)
Box 12.6 in Economics (eleventh edition) and Case study 8.16 on the Essentials of Economics (ninth edition) student website looks at these costs and benefits. The above table is taken from the box/case study. Net transport benefits (present value at 2015 prices) were estimated to be £74.2bn. These include benefits to passengers from shorter journey times, greater reliability, greater connectivity and less crowding, and reduced congestion on roads. They also include other benefits, such as a reduction in carbon emissions and a reduction in road accidents. Net benefits also include the wider benefits from greater connectivity between firms (resulting in increased specialism, trade and investment), greater competition and greater labour mobility. These wider benefits were estimated to be £20.5bn, giving total net benefits of £94.7bn.
Total costs to the government were estimated to be £108.9bn and revenues from fares to be £45.4bn, giving total net costs of £63.5bn. This gave a benefit/cost ratio of 1.5 (£94.7bn/£63.5bn). In the light of these findings, the government announced in September 2020 that the main work on the London to Birmingham leg would begin, despite the Public Accounts Committee’s finding that the project was badly off course and lacking in transparency.
Concern was expressed over whether the Leeds leg would go ahead, but in May 2021, the transport secretary, Grant Shapps, confirmed that it would be completed. However, with the publication of the Integrated Rail Plan in November 2021 (for a link, see list of reports below), the government decided that the eastern leg of HS2 would no longer reach Leeds but instead end in the East Midlands. Then in June 2022, the link between the HS2 line near Manchester and the West Coast Main Line was scrapped. This would have allowed HS2 trains to reach Scotland.
In early 2023, it was announced that the building of the terminus at Euston was being put on hold. Many interpreted this as meaning that it was being scrapped, with trains terminating at Old Oak Common, some six miles from Central London.
Finally, as we have seen, HS2 north of Birmingham has now been scrapped and the government is seeking private-sector funding to build the terminus at Euston and complete the line from Old Oak Common.
Arguments for scrapping the northern legs
The main argument given by the government was that projected costs have risen substantially above original estimates and that by cancelling the Manchester and east Midlands legs, the money saved could be better used elsewhere. The argument is one of opportunity cost. The cost of going ahead would mean not going ahead with better-value alternatives.
The government claims that £36bn will be saved and that this will be diverted to rail, road and other transport projects, primarily (although not exclusively) in the north of England. The money would be spent between 2029 and 2040. Projects include spending additional money on the planned upgrading of the rail link between Manchester and Liverpool, Sheffield, Leeds and Hull; building a new station at Bradford; developing a mass transit system for Leeds and its surroundings; a £2.5bn fund for improved transport for smaller cities, towns and the countryside in the north of England; extra funding for transport in the east and west Midlands, including funding a Midlands Rail Hub. Out of the £36bn, £6.5bn would be for projects elsewhere, including road improvement.
In order to judge whether the diversion of funds represents a better use of money, a full analysis of costs and benefits of the various projects would need to be conducted and compared with an updated cost–benefit analysis of continuing with the legs to Manchester and the east Midlands and possibly reinstating the Leeds leg too.
One possible benefit for the government is a political one. It hopes that promising more local projects rather than HS2 will appeal to the electorate in large parts of the north of England who are suffering from poor and unreliable transport links. However, most of these projects will be started well beyond the next election and this political gain may turn out to be small. Indeed, cancelling HS2 may breed cynicism, with people wondering whether any promised new projects will actually be delivered.
Arguments against scrapping the northern leg(s)
The benefits originally identified from HS2 will now be lost. It is not just that the northern legs of HS2 would have provided faster travel to Manchester and Leeds, but the new lines would have reduced congestion for slower trains and freight on existing lines. This has been the experience in countries such as Japan and Spain, which have invested heavily in new, separate high-speed lines.
When the line is completed to Birmingham, the HS2 trains will be able to continue north of Birmingham on existing lines. But these lines are heavily congested, which will limit the number of HS2 trains that can use them. Also they will be restricted to 110 mph on these lines as they have no tilting mechanism. Also they will have a maximum capacity of only 550 seats (a single train set) as the platforms at Manchester Piccadilly cannot accommodate double-set trains. The existing Pendalino trains on the West Coast mainline can travel at 125 mph as they do have the tilting mechanism and they have a higher capacity of 607 seats.
Then there are the signals that cancellation sends to industry about whether governments can be trusted to follow through on public-sector projects. Many business had expanded or relocated to places near the HS2 routes. Many others will wonder whether the promised new projects will go ahead. Indeed, shortly after giving a list of the projects (some of which had already been built or were being built), the list was removed from the government website. There is already a mood of scepticism amongst the electorate. Polling following the initial announcement showed that a majority believed that it was unlikely that the Conservatives would deliver the other projects if they won the next election.
The opportunity cost argument that the money would be better spent on alternative transport projects is predicated on various assumptions. One is that the money will actually be spent, which, as we have seen, people consider doubtful. Another is that the only choice is either spending a fixed pot of money on the northern leg(s) of HS2 or spending it on the alternative projects announced by the prime minister. It could be argued that the government should proceed with both the full HS2 and these other projects, and fund it by extra taxation. Investment as a percentage of GDP is low in the UK compared with other countries. Over the past 10 years, it has averaged 17.8% in the UK. This compares with 21.0% in the USA, 21.5% in Germany, 23.7% in France and 25.4% in Japan. Also, public-sector investment is low in the UK compared with that in other countries.
Assessing the arguments
Many of the costs and benefits of long-term projects, such as HS2, occur many years hence. There is, therefore, a great deal of uncertainty over their magnitude. This makes it extremely difficult to reach a clear conclusion over the desirability of cancelling HS2 north of Birmingham or continuing with it. Under such circumstances, politics tends to dominate decision making.

Over the decades, economies have become increasingly interdependent. This process of globalisation has involved a growth in international trade, the spread of technology, integrated financial markets and international migration.
When the global economy is growing, globalisation spreads the benefits around the world. However, when there are economic problems in one part of the world, this can spread like a contagion to other parts. This was clearly illustrated by the credit crunch of 2007–8. A crisis that started in the sub-prime market in the USA soon snowballed into a worldwide recession. More recently, the impact of Covid-19 on international supply chains has highlighted the dangers of relying on a highly globalised system of production and distribution. And more recently still, the war in Ukraine has shown the dangers of food and fuel dependency, with rapid rises in prices of basic essentials having a disproportionate effect on low-income countries and people on low incomes in richer countries.
Moves towards autarky
So is the answer for countries to become more self-sufficient – to adopt a policy of greater autarky? Several countries have moved in this direction. The USA under President Trump pursued a much more protectionist agenda than his predecessors. The UK, although seeking new post-Brexit trade relationships, has seen a reduction in trade as new barriers with the EU have reduced UK exports and imports as a percentage of GDP. 
According to the Office for Budget Responsibility’s November 2022 Economic and Fiscal Outlook, Brexit will result in the UK’s trade intensity being 15 per cent lower in the long run than if it had remained in the EU.
Many European countries are seeking to achieve greater energy self-sufficiency, both as a means of reducing reliance on Russian oil and gas, but also in pursuit of a green agenda, where a greater proportion of energy is generated from renewables. More generally, countries and companies are considering how to reduce the risks of relying on complex international supply chains.
Limits to the gains from trade
The gains from international trade stem partly from the law of comparative advantage, which states that greater levels of production can be achieved by countries specialising in and exporting those goods that can be produced at a lower opportunity cost and importing those in which they have a comparative disadvantage. Trade can also lead to the transfer of technology and a downward pressure on costs and prices through greater competition.
But trade can increase dependence on unreliable supply sources. For example, at present, some companies are seeking to reduce their reliance on Taiwanese parts, given worries about possible Chinese actions against Taiwan.
Also, governments have been increasingly willing to support domestic industries with various non-tariff barriers to imports, especially since the 2007–8 financial crisis. Such measures include subsidies, favouring domestic firms in awarding government contracts and using regulations to restrict imports. These protectionist measures are often justified in terms of achieving security of supply. The arguments apply particularly starkly in the case of food. In the light of large price increases in the wake of the Ukraine war, many countries are considering how to increase food self-sufficiency, despite it being more costly.
Also, trade in goods involves negative environmental externalities, as freight transport, whether by sea, air or land, involves emissions and can add to global warming. In 2021, shipping emitted over 830m tonnes of CO2, which represents some 3% of world total CO2 emissions. In 2019 (pre-pandemic), the figure was 800m tonnes. The closer geographically the trading partner, the lower these environmental costs are likely to be.
The problems with a globally interdependent world have led to world trade growing more slowly than world GDP in recent years after decades of trade growth considerably outstripping GDP growth. Trade (imports plus exports) as a percentage of GDP peaked at just over 60% in 2008. In 2019 and 2021 it was just over 56%. This is illustrated in the chart (click here for a PowerPoint). Although trade as a percentage of GDP rose slightly from 2020 to 2021 as economies recovered from the pandemic, it is expected to have fallen back again in 2022 and possibly further in 2023.
But despite this reduction in trade as a percentage of GDP, with de-globalisation likely to continue for some time, the world remains much more interdependent than in the more distant past (as the chart shows). Greater autarky may be seen as desirable by many countries as a response to the greater economic and political risks of the current world, but greater autarky is a long way from complete self-sufficiency. The world is likely to remain highly interdependent for the foreseeable future. Reports of the ‘death of globalisation’ are premature!

For those of you embarking on a course in economics, one of the first things you’ll come across is the distinction between microeconomics and macroeconomics. The news is full of both microeconomic and macroeconomic issues and you’ll quickly see how relevant both branches of economics are to analysing real-world events, problems and policies.
As we state in Economics (updated 10th edition), ‘microeconomics is concerned with the individual parts of the economy. It is concerned with the demand and supply of particular goods, services and resources such as cars, butter, clothes, haircuts, plumbers, accountants, blast furnaces, computers and oil.’ In particular, it is concerned with the buying, selling, production and employment decisions of individuals and firms. When you go shopping and make choices of what to buy you are making microeconomic decisions. When firms choose how much of particular products to produce, what techniques of production to use and how many people to employ, these choices are microeconomic ones.
Microeconomics examines people’s behaviour when they make choices. In fact many of the recent developments in microeconomics involve analysing the behaviour of individuals and firms and the factors that influence this behaviour.
Open any newspaper, turn on the TV news or access any news site and you will see various microeconomic issues covered. Why are rents soaring? How is AI affecting various businesses’ productivity? How rapidly is the switch taking place to green energy? How do supermarkets influence spending patterns? Why are wages so low in the social care sector? Why are private PCR tests so expensive for holidaymakers retuning from abroad?
Many of the blogs on this news site will examine microeconomic issues. We hope that they provide useful case studies for your course.

The EU has recently signed two trade deals after many years of negotiations. The first is with Mercosur, the South American trading and economic co-operation organisation, currently consisting of Brazil, Argentina, Uruguay and Paraguay – a region of over 260m people. The second is with Vietnam, which should result in tariff reductions of 99% of traded goods. This is the first deal of its kind with a developing country in Asia. These deals follow a recent landmark deal with Japan.
At a time when protectionism is on the rise, with the USA involved in trade disputes with a number of countries, such as China and the EU, deals to cut tariffs and other trade restrictions are seen as a positive development by those arguing that freer trade results in a net gain to the participants. The law of comparative advantage suggests that trade allows countries to consume beyond their production possibility curves. What is more, the competition experienced through increased trade can lead to greater efficiency and product development.
It is estimated that the deal with Mercosur could result in a saving of some €4bn per annum in tariffs on EU exports.
But although there is a net economic gain from greater trade, some sectors will lose as consumers switch to cheaper imports. Thus the agricultural sector in many parts of the EU is worried about cheaper food imports from South America. What is more, increased trade could have detrimental environmental impacts. For example, greater imports of beef from Brazil into the EU could result in more Amazonian forest being cut down to graze cattle.
But provided environmental externalities are internalised within trade deals and provided economies are given time to adjust to changing demand patterns, such large-scale trade deals can be of significant benefit to the participants. In the case of the EU–Mercosur agreement, according to the EU Reporter article, it:
…upholds the highest standards of food safety and consumer protection, as well as the precautionary principle for food safety and environmental rules and contains specific commitments on labour rights and environmental protection, including the implementation of the Paris climate agreement and related enforcement rules.
The size of the EU market and its economic power puts it in a strong position to get the best trade deals for its member states. As EU Trade Commissioner, Cecilia Malmström stated:
Over the past few years the EU has consolidated its position as the global leader in open and sustainable trade. Agreements with 15 countries have entered into force since 2014, notably with Canada and Japan. This agreement adds four more countries to our impressive roster of trade allies.
Outside the EU, the UK will have less power to negotiate similar deals.
