UK Productivity vs Other Advanced Economies

The UK’s productivity and innovation performance lags behind most other advanced economies, particularly the US, Germany, and France, despite having a strong record of scientific research and patenting. This article explains the key gaps, the reasons behind them, and how the UK compares across various measures.

Background: The Productivity Puzzle

Productivity—output per hour worked—is the main driver of living standards. Since the 2008 financial crisis, the UK has experienced its slowest productivity growth in decades, a phenomenon often called the ‘productivity puzzle’. While most advanced economies saw a slowdown, the UK’s stagnation has been more severe and prolonged. By 2023, UK labour productivity was roughly 15-20% below the average of other G7 economies, a gap that has widened since the mid-2000s.

How Productivity Is Measured

Economists typically compare productivity using two main metrics:

• Labour productivity: GDP per hour worked or per worker. This is the most common measure and reflects the efficiency of workers.
• Total factor productivity (TFP): The portion of output not explained by the amount of inputs used (capital and labour). TFP captures technological progress, innovation, and efficiency gains.

Innovation is often measured through R&D spending, patent applications, and the adoption of new technologies (like robotics or AI). The UK’s R&D intensity—gross domestic expenditure on R&D as a percentage of GDP—has hovered around 1.7%, below the OECD average of 2.7% and well below Germany’s 3.1% and the US’s 3.5%.

The UK’s Innovation Strengths

The UK is a global leader in scientific research. It produces a disproportionately high number of highly cited scientific papers and has world-class universities (Oxford, Cambridge, Imperial College). The UK also files a significant number of patents per capita and has a thriving tech start-up scene, particularly in fintech, AI, and life sciences. For example, the UK’s ‘unicorn’ companies (start-ups valued at over $1 billion) are second only to the US and China. Yet this research strength does not translate into economy-wide productivity gains as effectively as it does in other countries.

Why the UK Lags: Key Factors

Several structural issues explain the UK’s productivity underperformance:

• Low investment: The UK has chronically underinvested in physical capital (machinery, equipment, infrastructure) compared to peers. Business investment as a share of GDP has been among the lowest in the G7 for decades.
• Weak management and diffusion: The UK has a ‘long tail’ of poorly managed firms, particularly in retail and hospitality, that fail to adopt best practices or new technologies. The gap between the most productive and least productive firms is wider in the UK than in most advanced economies.
• Skills shortages: Despite having top universities, the UK has a relatively high proportion of workers with low literacy and numeracy skills compared to other advanced economies, and vocational training is often weaker than in Germany or Switzerland.
• Regional disparities: Productivity is highly concentrated in London and the South East. Other regions, such as Wales, the North East, and Northern Ireland, have productivity levels far below the national average, dragging down overall performance.
• Uncertainty and policy volatility: The 2016 Brexit referendum and subsequent withdrawal from the EU created prolonged uncertainty, which may have dampened investment and trade, both of which are linked to productivity.

Comparison with Other Advanced Economies

To put the UK in context, here are some key comparisons:

• United States: The US has higher labour productivity and faster TFP growth, driven by massive investment in technology, a large domestic market, and a culture of risk-taking. The UK’s productivity is about 20-25% below the US level.
• Germany: Germany’s productivity is significantly higher than the UK’s, thanks to its strong manufacturing base, high investment in machinery, and a robust vocational training system. The UK’s productivity is roughly 15% below Germany’s.
• France: France has higher labour productivity than the UK, despite a shorter average working week, due to higher capital intensity and better management practices in its largest firms.
• Japan and Italy: The UK is broadly on par with or slightly ahead of Japan and Italy, but these countries are also struggling with low productivity growth, so the UK is not exceptional in this company.

In terms of innovation, the UK performs well on research outputs but poorly on business R&D. Business-funded R&D in the UK is only about 1.1% of GDP, compared to 1.9% in the US and 2% in Germany. This suggests that UK firms are less willing or able to turn research into commercial products.

Common Misconceptions

One common misconception is that the UK’s productivity problem is due to a large public sector or high taxes. In reality, the private sector accounts for most of the gap. Another is that the UK is a ‘low-wage, low-skill’ economy across the board. While that is true for a large segment, the UK also has a highly productive ‘frontier’ of firms in sectors like finance and tech that compete globally. The issue is the middle and lower tiers, which drag down the average.

Policy Responses and Outlook

Successive UK governments have introduced policies aimed at boosting productivity, such as the ‘levelling up’ agenda (addressing regional disparities), increased funding for R&D (targeting 2.4% of GDP), and reforms to the planning system to speed up infrastructure projects. The impact of these policies is yet to be fully felt. The adoption of AI and digital technologies could offer a new opportunity to close the gap, but the UK’s low investment in intangible capital (software, data, organisational capital) may hinder this.

Frequently Asked Questions

Is the UK more innovative than Germany?

In scientific research, yes—the UK publishes more highly cited papers and has more top-ranked universities. But in commercial innovation, Germany outperforms the UK due to higher business R&D spending and a stronger manufacturing base. Germany’s companies are more likely to patent and bring products to market.

Why is UK productivity lower than the US?

The US benefits from a larger domestic market, deeper capital markets, higher business investment, and a more flexible labour market. US firms also adopt new technologies faster and have better management practices on average. The UK’s smaller market and lower investment levels contribute to the gap.

Does Brexit affect productivity?

Most economists agree that Brexit has increased uncertainty, reduced trade with the EU, and made it harder for firms to hire skilled workers from abroad—all of which can dampen productivity. However, the UK’s productivity slowdown began well before the referendum, so Brexit is not the sole cause.

What can be done to improve UK productivity?

Key measures include increasing public and private investment, improving managerial skills, boosting vocational training, reducing regional disparities, and encouraging the diffusion of technology from frontier firms to laggards. There is no single silver bullet, and progress will take years.

Is productivity the same as innovation?

No. Innovation is about creating new products, processes, or technologies. Productivity is about how efficiently outputs are produced. Innovation can boost productivity, but other factors like capital investment, skills, and management also matter. The UK is innovative in research but less effective at turning that into productivity gains.
