The British disease: what explains the relative decline of the UK economy?

Britain established global leadership in manufacturing, innovation and exports in the Industrial Revolution. Relative economic decline from around 1870 was an outcome of comparator countries catching up and overtaking. But there have also been policy failures and persistent institutional weaknesses.

The UK has a new prime minister, Andy Burnham, who has once again emphasised economic growth as a key policy objective. Indeed, he is targeting ‘growth in every postcode’.

In a speech to the Treasury in July, the new chancellor, John Healey, declared that ‘every government department is a growth department. We’ll make the fullest possible use of public investment within our fiscal framework, and we’ll take the fullest advantage of private and international investment – ready to back Britain’.

Within this statement is an implicit assumption that it is investment that has held the economy back. While the UK has had lower investment rates than other OECD countries, the problem is older and more persistent than today’s investment debate suggests, and apparent periods of recovery may obscure that persistence.

Labour was elected only two years ago on a promise to ‘kick-start’ economic growth, yet those plans have already stalled. Nor is this a new pattern: the growth plans of the Labour government elected in 1964 were similarly short-lived. The ‘British disease’ – of an underperforming economy – was never fully cured nor diagnosed, and in recent years, it has reappeared in a more virulent form. Without a full assessment, politicians will be unable to fix it.

How has the UK economy grown under different governments since 1945?

Growth in GDP per capita and productivity (as measured by total factor productivity, TFP) has fallen since the 1940s (see Figure 1). When set against the record of post-war governments, the years from 1951 to 1964 appear economically impressive. They combined strong economic growth with relatively low inflation and unemployment.

This lends support to Harold Macmillan’s view that ‘most of our people have never had it so good’. Early in this time in office as prime minister (1957-63), he said: ‘Go around the country, go to the industrial towns, go to the farms and you will see a state of prosperity such as we have never had in my lifetime – nor indeed in the history of this country.’

But the issue is not so much the UK’s performance relative to its past but how it compared to that of other countries (see Figure 2). This is more informative, revealing that the UK performed worse than its European peers, particularly in the so-called Golden Age from 1945 to the early 1970s (Crafts, 1995).

European countries experienced higher levels of growth and converged on UK levels of GDP per capita (Crafts, 2018). Much of the European growth was a return to trend growth that was disrupted by the two world wars (Crafts and Mills, 1996).

The UK was an outlier. One noticeable aspect was its persistently weak productivity performance compared with European peers (see Figure 3). This was noted at the time by a team of economists from the Brookings Institution (see Britain’s Economic Prospects).

What might explain these differences in economic performance?

Economic growth in the UK since 1945 suggests that there is a deeper story to be told. Economic history is shaped by connected pasts and not isolated events. Britain’s economic history can be categorised into three broad phases.

The Industrial Revolution – from the 1700s to approximately 1870 – was when the country established global leadership. Its manufacturing output, technological innovation and export capacity positioned it as the ‘workshop of the world’.

This is the period of British economic history that has attracted the most attention. For example, two high profile meta-analyses have emphasised both the supply and demand for innovation during the Industrial Revolution and how these differed from circumstances elsewhere (Mokyr, 2009; Allen, 2009).

The quest to explain why Britain started the world on the path to modern economic growth has been described as a search for ‘the holy grail’ (Crafts, 2011). Most recent contributions in this space have focused on when growth began (Bouscasse et al, 2025) using constructed estimates of GDP that stretch back to the 1200s (Broadberry et al, 2015).

In comparison, the latter phases of British economic history, while well studied, have not received the same amount of scholarly attention. In fact, some see Britain’s subsequent decline as almost inevitable because technological leadership is ephemeral (Mokyr, 2009).

The second phase from 1870 to 1914 was a period of relative decline as technological leadership was lost to Germany and the United States (Broadberry, 1998; Broadberry, 2006). From the late 19^th century, other countries began to industrialise rapidly. Germany and the United States, in particular, benefited from later industrialisation, which allowed them to adopt newer technologies and organisational forms. As a result, they experienced faster growth rates in manufacturing and productivity.

It was during the period from 1870 to 1914 that the United States became the first country to converge with and then overtake the UK in terms of GDP per capita (Crafts, 1998). The UK remained a growing economy in absolute terms, but it experienced relative decline compared with Germany, the United States and others (Pollard, 1983; Crafts, 2018).

Between 1870 and the First World War, the UK did not stop growing and GDP per capita continued to rise over time. But growth was slower than in comparator economies. This divergence is what constitutes relative decline – the UK was no longer a leader, but it had not completely stagnated.

The period from 1914 to 1970 further entrenched these trends. The decline of staple industries, combined with the economic disruptions of two world wars, led to persistent unemployment and regional disparities. Industrial regions in the North and Midlands were particularly affected.

The concept of path dependence – that early choices shape later outcomes – is central to understanding Britain’s economic trajectory. Rather than viewing decline as a sudden failure, we should see Britain’s later underperformance as deeply rooted in its early success (Harley, 2014).

The Industrial Revolution created a specific configuration of industries, institutions and capabilities. These generated powerful positive feedback effects, clusters of skills, capital and infrastructure, but they also made adaptation to changes much more difficult.

For example, ‘agglomeration economies’ reinforced the dominance of particular sectors, such as textiles, coal and steel (Crafts and Wolff, 2014). These industries became regionally concentrated, creating local specialisation but also vulnerability to structural change (Heblich et al, 2025). Over time, such specialisation could become a constraint rather than an advantage, especially when new technologies emerged elsewhere.

Another aspect of this debate concerned trade policy. Germany and the United States combined high tariff barriers that protected nascent industries with high rates of economic growth. This became known as the ‘tariff-growth paradox’, as it ran counter to the conventional view that free trade was good for growth (O’Rourke, 2000).

The success of Germany and the United States therefore prompted a strand of research asking whether Britain might have benefited from using tariffs to protect new industries. If the country’s resources were locked into an established pattern of production, tariff protection offered one possible means of encouraging the development of newer industries (Richardson, 1965).

But the effectiveness of such protection would probably have been limited. In practice, protection was more likely to have been directed towards older, labour-intensive industries than the newer, more capital-intensive industries of the second Industrial Revolution (Crafts, 2018).

The emphasis on historical shocks, particularly wars, is also important. For example, one recent study emphasises the influence of labour shortages during the Napoleonic wars as a key spur for innovation (Voth et al, 2026). Later wars did not have the same effect and rather than acting as clean breaks – whereby interest groups were replaced by new groups able and willing to promote economic reform (Olson, 1982) – these shocks often intensified existing patterns.

Wartime mobilisation strengthened state involvement in the economy and reinforced the importance of traditional industries in the 20^thcentury. Thus, the relative decline of the UK is seen as a long-run, cumulative process, shaped by both continuity and disruption.

Just as the ‘early start’ pushed Britain down a path where it grew slower than its rivals, the country’s very stability meant that there was little impetus for reform, even if the need for it had been recognised. In the UK, wartime crises stimulated growth in public expenditure and weakened resistance to the taxation needed to fund such spending (Peacock and Wiseman, 1961).

The net result of these pressures was a ‘displacement effect’ whereby the scale of the state grew on the back of national upheaval but did not shrink back to pre-crisis levels when more normal times returned.

How might we understand this British disease?

Much of the historiography of British decline and the British disease is concerned with when the country began falling behind, why it did so, and whether this reflected fundamental weaknesses in the British economic model or the inevitable convergence of its competitors.

Interpretations have ranged from relatively optimistic to more pessimistic assessments of the UK’s economic performance (see, for example, McCloskey, 1970; Crafts, 1979; and Elbaum and Lazonick, 1984).

The theme of decline became particularly pertinent in the 1970s. Some saw Britain’s imperial decline through the lens of relative decline: national power had to be judged against both the growing strength of rival states and the scale of Britain’s global commitments (Barnett, 1972). By 1940, Britain was trying to sustain an enormous imperial and military role with an industrial and technological base that had fallen behind its competitors, leaving it increasingly dependent on the productive capacity of the United States.

The concept of the British disease emphasises structural and institutional weaknesses (Allen, 1979). These include low levels of investment in the UK and a failure to modernise the country’s industrial base.

Crucially, this work highlights the absence of new firms and technologies replacing old ones (termed creative destruction by economist Joseph Schumpeter). Cultural factors, such as the British elite’s preference for non-industrial pursuits and the persistence of outdated institutions, are also said to have limited the dynamism of the economy (Allen, 1979).

Researchers have also argued that the roots of economic malaise in the 1970s – ushered in by the failings of industrial relations and the public sector – could be traced back to a century earlier and that the UK was too slow to learn from other more successful economies (Allen, 1951; Allen, 1946). For example, when discussing the increases in Germany’s coal mining productivity relative to Britain’s during the 1930s, it has been argued that improvements in organisation rather than capital were crucial.

In particular, it is argued that social and political obstacles in Britain held back efficiency in ways that other major developed economies did not face (Allen, 1979). Institutions and habits of mind – such as amateurism within management and an undersupply of graduate engineers in some industries – acted as brakes on the British model. The argument was that a complete overhaul of British institutions, particularly universities where there should be greater emphasis on business education, was needed (Allen, 1979).

The solution would therefore be a more meritocratic public and private sector – in short, that British society needed to learn to live with the realities of creative destruction even if there was no love for it.

Others have offered a more nuanced view, arguing that while the UK experienced relative decline in the late 19^th century, the economy remained fundamentally sound until the mid-20^th century (Pollard, 1989). The more serious problems emerged after 1945, when the UK failed to keep pace with other advanced economies during the post-war boom (Pollard, 1982).

The picture is complicated further when the very concept of ‘decline’ is questioned (Tomlinson, 1996) – specifically, arguing that comparisons must consider what was feasible given Britain’s starting position. From this perspective, the country’s performance may have been less disappointing than often assumed (Crafts, 2018).

Curing the British disease

The British disease seemed to have been tamed but there is no consensus as to why this happened. One view is that competition ‘cured the British disease’, driven somewhat by the supply-side reforms – such as privatisation and labour market legislation – made during Margaret Thatcher’s time in office as prime minister (1979-91). This increased competition came after the UK joined the European Economic Community and British proposals to improve the single market; although this has partly been reversed since the UK left the European Union.

Another view was that Britain struck ‘black gold’ and became a net energy exporter, but this was only a temporary fix and the UK returned to being a net importer after 2005 (Phelps Brown, 1983).

Indeed, the easing of the British disease has been attributed to the enormous benefit to the UK economy from a resource boom after the discovery of North Sea oil (McLaughlin, 2026). At the nadir of the UK’s slow growth, the government needed a bailout from the International Monetary Fund (IMF) to support sterling. After North Sea oil came on stream, it was able to repay the IMF loan. The Financial Times even ran a headline ‘From the IMF to the North Sea’ (Roberts, 2016).

The more fundamental point though was that the UK failed to manage its inclusive wealth. The proceeds of North Sea oil, which accounted for around a quarter of economic growth in the early 1980s, were not converted into other forms of capital (Solow, 1986; McLaughlin, 2026).

Unlike Norway, the UK never established a sovereign wealth fund to preserve part of the energy windfall for future generations (Atkinson and Hamilton, 2020). Educational attainment continued to lag behind comparator countries too.

This raises an awkward possibility: perhaps the British disease was never cured at all. The reforms of the Thatcher governments mattered, but they coincided with an extraordinary resource windfall. North Sea oil eased the external constraint, strengthened the public finances and contributed substantially to growth.

But the UK spent the proceeds rather than converting a temporary depletion of natural wealth into lasting financial, produced or human capital. The symptoms improved, but the underlying disease remained.
