Gross Domestic Product (GDP)

A measure of productivity that captures the effects of technology, innovation, management quality, and other intangible factors that increase output beyond what can be explained by the quantity of labour and capital inputs used. TFP is calculated as GVA divided by a weighted combination of labour and capital inputs.

An increase in the amount of capital available per worker, which typically raises labour productivity. In modern economies, capital deepening increasingly involves investment in intangible assets — software, data infrastructure, organisational capital, and human capital — rather than traditional machinery and equipment.

A set of measurement guidelines and statistical standards developed by the Organisation for Economic Co-operation and Development for comparing productivity across countries and sectors. The OECD framework addresses the treatment of intangible investment, quality adjustment, and multi-factor productivity, providing the foundation for international productivity benchmarking.

The Confederation of British Industry — the United Kingdom's premier business organisation, representing over 190,000 businesses that together employ approximately seven million people. The CBI provides a voice for businesses of all sizes to government, policymakers, and international institutions on issues including productivity, investment, regulation, and trade.

A professional who studies, analyses, and interprets the production, distribution, and consumption of goods and services. Economists apply quantitative and qualitative methods to understand economic behaviour at both micro and macro levels, informing policy decisions, business strategy, and investment analysis.

The system of statistical methods used to measure a country's overall economic activity, including Gross Domestic Product (GDP), Gross National Income (GNI), and related aggregates. National income accounting provides the framework for tracking economic output, income distribution, saving, investment, and international trade flows.

A UK government economic development initiative launched in 2014 aimed at boosting economic growth and productivity in the north of England by investing in transport infrastructure, science and innovation, devolution, and skills development. The Northern Powerhouse agenda is closely linked to intangible asset development because closing the productivity gap between northern and southern England requires investment in precisely the intangible factors that drive modern economic growth: research and innovation capacity, workforce skills, digital infrastructure, and the agglomeration effects created by better-connected cities.

The Organisation for Economic Co-operation and Development — an intergovernmental body of 38 member countries committed to promoting policies that improve economic and social well-being. The OECD plays a pivotal role in intangible asset and productivity research, producing influential studies on the measurement and economic impact of intangible investment, knowledge-based capital, and innovation.

The AI Productivity Paradox: Why Trillions in AI Spending Aren't Moving the Needle

Global AI investment has surpassed $500 billion annually, yet total factor productivity growth remains stubbornly flat. This is Solow's paradox reborn: you can see AI everywhere except in the productivity statistics. History tells us why — and what needs to change.

What is growth accounting?

Growth accounting is a framework that decomposes economic or business output growth into contributions from labour, capital, and productivity (TFP).

What is the impact of AI on Total Factor Productivity and intangible capital?

AI amplifies Total Factor Productivity by enabling firms to extract more output from the same inputs, with the productivity gains increasingly attributable to intangible capital — data, algorithms, and organisational knowledge — rather than physic...

What is Total Factor Productivity (TFP)?

TFP measures the portion of output growth that cannot be explained by increases in labour or capital inputs — it captures the efficiency gains from innovation, technology, and better management.
