Closing the Global Productivity Gap Through Technology Adoption

Abstract

The global productivity gap remains one of the most important structural inequalities in the world economy. In 2024, a worker in a low-income economy produced roughly one-twentieth as much output as a worker in a high-income economy, and much of this disparity is explained not by differences in labor effort or capital alone, but by differences in technology, management practices, infrastructure, and the ability to use existing knowledge effectively. This report examines whether technology adoption and diffusion can serve as a principal mechanism for narrowing productivity gaps between countries and whether such convergence contributes to Polycrisis Resilience, defined within the H Heuristics framework as the capacity of societies to anticipate, withstand, adapt to, recover from, and reduce vulnerability to multiple interconnected crises. Using public data covering 217 economies from 1991 to 2024, the report measures the scale and sources of the productivity gap, analyzes historical patterns of technology diffusion, evaluates the relationship between technology adoption and productivity growth, and assesses how productivity contributes to resilience outcomes. The findings indicate that technology adoption can support catch-up growth, but the effect is conditional rather than automatic. While access to technologies such as mobile communications, internet connectivity, digital finance, and renewable energy has expanded rapidly, productive use often remains constrained by deficits in reliable power, skills, finance, competition, institutions, and local adaptive capacity. The evidence suggests that adoption contributes most effectively to productivity growth when these complementary conditions are present. The report argues that closing the productivity gap is a proactive resilience strategy because higher productivity expands the resources available to households, firms, and governments for preparation, protection, adaptation, and recovery. Scenario analysis to 2100 suggests that pathways which successfully convert technology adoption into sustained productivity gains could substantially narrow global productivity disparities, improve coping capacity, and reduce vulnerability across multiple systems. The central conclusion is that technology itself is not scarce; the conditions that enable its effective use are. Strengthening those conditions represents one of the most practical routes through which technology diffusion can enhance global economic convergence and build Polycrisis Resilience.

Key findings

1. The gap is mainly a productivity gap. Differences in output per worker explain 86% of the differences in income per person between countries. Output per worker in developing economies rose from 14% of the high-income level in 1991 to 27% in 2024, but without China and India it stayed at 24%.
2. Most of the gap is not about machines or buildings. Of the shortfall in developing economies, 71% sits in total factor productivity (mostly technology and how well it is used), 22% in skills and only 7% in capital per worker.
3. Basic technologies spread quickly. Productive ones lag. In lower-middle-income countries mobile subscriptions stand at 77% of the high-income level and internet use at 60%, but fixed broadband is at 6% and electricity use per person at 10%. Among firms in low-income countries 57% use e-mail with customers and 26% have a website, against 94% and 68% in high-income countries.
4. New technologies spread faster than old ones. It took the United States 43 years for the telephone to go from 10% to 50% of households, 17 for electricity and 9 for the internet. Mobile phones let low-income economies skip landlines almost entirely.
5. Adoption is linked to productivity growth, but the link is modest and conditional. Across 153 economies, an extra percentage point a year of internet adoption goes with 0.37 points a year of extra productivity growth in developing economies, and with nothing measurable in high-income ones. Getting people online is necessary groundwork. It is not enough.
6. Productivity buys resilience. Output per worker explains 70% of the variation in countries’ lack of coping capacity but only 3% of natural-hazard exposure. Tax revenue per worker is $676 in low-income countries and $18,391 in high-income ones, which is why the productivity gap is also a gap in the ability to protect people.
7. Three pathways to 2100 lead to very different worlds. If adoption does not turn into catch-up, developing economies fall from 27% to 20% of high-income output per worker by 2100; at their 2000–19 pace they reach 39%; with the conditions that make adoption pay, at the best-performing tenth’s pace, 54%. Cumulative child deaths in 2025–2100 are 285, 187 and 150 million. These are conditional illustrations, not forecasts.
