The resilience of the global economy over the coming decades will depend on geopolitics, supply chain evolution, technology, and demographic trends.
Fertility rates have fallen sharply in many countries, most notably in Asia, where even the fastest-growing economies have struggled to boost family size. Recent months have seen record lows in Japan, Singapore, Taiwan, and China, despite a range of incentives aimed at easing the financial burden of parenting. Cultural expectations, such as the need for women to balance career and family and for supportive partners, continue to hinder progress.
Academic research offers a counterpoint to widespread pessimism. A study led by scholars including Daron Acemoglu and David Autor found that output per worker increased between 1970 and 2020 despite declining birth rates, suggesting that lower fertility can raise GDP per employee.
The authors argue that labor scarcity drives rapid adoption of labor‑saving technologies, boosting productivity. Their analysis links each one‑percentage‑point drop in fertility to roughly a 27% rise in worker output across countries.
Investment in technology is therefore crucial, especially for export‑oriented economies such as South Korea, where labor‑saving innovations are expected to dominate overseas shipments.
Historically, governments have managed population growth as a development tool, but reversing that trend proves difficult. Singapore’s leadership has acknowledged the lack of clear solutions and emphasized improving the quality of life for existing families.
The study cautions against over‑extending its findings into the distant future, recognizing that demographic shifts may accelerate and introduce new challenges.
Policymakers face real concerns about shrinking school enrollments, strained healthcare and pension systems, and a narrowing tax base. Issues such as China’s underfunded pension scheme, the projected shortfall in U.S. Social Security, and early aging in emerging markets underscore the urgency.
Efforts to restore replacement‑level fertility to 2.1 children per woman appear unrealistic, though modest gains have been noted in South Korea, where marriage rates have risen and the fertility rate has edged up slightly, remaining far below the target.
Practical solutions include immigration and automation. While immigration can be politically contentious, automation aligns with the current artificial‑intelligence boom and could offset labor shortages.
Technology not only replaces scarce labor but also enhances productivity among existing workers and smaller families, potentially spurring further innovation. Population decline is not imminent, and global headcount is unlikely to reverse for at least another half‑century, suggesting that current anxieties may be premature.
