Why some nations thrive while others struggle is a matter of efficiency
In short: The fundamental divide between rich and poor nations isn't just about how much they produce, but how efficiently they do it. Productivity is the engine of wealth, turning raw inputs into higher living standards through a delicate balance of new ideas, technological breakthroughs, and smarter business models.
Productivity is defined as the ability to generate more output by combining inputs more efficiently. While many look at Gross Domestic Product (GDP) as a raw measure of success, economists distinguish between 'capital deepening'—simply using more capital per hour worked—and 'multifactor productivity' (MFP). MFP is the more sophisticated metric, as it captures the efficiency of how capital and labor are combined, serving as a primary indicator of technological progress and innovation. These innovations are what ultimately transform the production of goods and services. They are the primary drivers for improving well-being and living standards. This report covers these trends across 38 OECD member countries.
The distinction matters because of how it explains economic growth. By using a growth accounting framework, researchers can break down GDP into three distinct components: labor inputs (employment and hours worked), capital inputs (investment), and MFP. This decomposition allows us to see whether a country is growing simply by working harder and using more machines, or by actually getting smarter about how those machines and people interact to create value. The analysis also looks at sectoral reallocation and firm size. It examines how investment trends influence these outcomes. These perspectives provide a comprehensive framework for evaluating economic performance.
Recent data highlights a troubling trend in this mechanism. In 2023, global and OECD economic growth slowed significantly, with OECD GDP growth dropping to 1.7% from 3.0% in 2022. Crucially, the 2023 growth was predominantly driven by increases in labor inputs rather than productivity improvements. Data indicates that 2023's hourly production failed to rise because of inadequate capital investment and productivity boosts, implying that fundamental systemic obstacles still prevent moving beyond simple resource gathering toward genuine innovation-driven expansion. This deceleration was caused by delayed monetary tightening and high inflation. Weak global trade and overlapping crises also played a role. The report provides experimental estimates for 2024 developments.
