Total Factor Productivity (TFP)

The observation that large-scale investments in information technology and digital transformation do not always produce corresponding improvements in measured productivity. The productivity paradox is partly explained by measurement challenges — traditional metrics fail to capture the full value of intangible asset accumulation — and partly by the time lag before complementary intangible investments yield returns.

The portion of economic output growth that cannot be explained by measurable increases in labour and capital inputs, named after economist Robert Solow. The Solow residual is often interpreted as a measure of technological progress and is closely related to total factor productivity, capturing the output gains attributable to intangible factors such as innovation, education, and institutional quality.

A classification framework for intangible investment developed by economists Carol Corrado, Charles Hulten, and Daniel Sichel. The CHS framework identifies three broad categories of intangible capital: computerised information (software, databases), innovative property (R&D, design, new products), and economic competencies (brand equity, organisational capital, firm-specific training).

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 total monetary value of all finished goods and services produced within a country during a specific time period. GDP is the broadest measure of national economic output and is widely used as a proxy for overall economic health.

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.

A measure of output that accounts for changes in the quality of goods and services produced, rather than simply measuring volume. Quality adjustment is essential for accurate productivity measurement, particularly in sectors where intangible investments drive improvements in product functionality, reliability, and user experience.

The total revenue opportunity available for a product or service if it achieved 100% market share. TAM represents the theoretical maximum market size and is used by investors to assess the scale of opportunity and the potential ceiling for a company's growth.

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.
