Research Question : How Does Population Aging Impact Economic Growth and Labor Productivity?

Population aging is changing the economies of many countries around the world. In ultra-aging societies such as Japan, the number of older adults continues to increase while the working-age population declines. This demographic shift has raised concerns about slower economic growth, labor shortages, and lower productivity. At the same time, it has encouraged governments and businesses to find new ways to maintain economic performance.

One of the biggest economic challenges of population aging is the decline in the labor force. As more people retire and fewer young workers enter the workforce, businesses often struggle to fill job vacancies. This labor shortage can reduce production, slow economic growth, and increase pressure on pension and healthcare systems. According to the Organisation for Economic Co-operation and Development (OECD), population aging is expected to slow GDP growth in many developed countries unless labor force participation and productivity improve.

However, an aging population does not necessarily lead to lower productivity. Many older workers continue to contribute valuable experience, professional knowledge, and mentoring skills in the workplace. In addition, labor shortages have encouraged companies to invest in automation, artificial intelligence (AI), and robotics to improve efficiency. Acemoglu and Restrepo (2017) argue that countries experiencing faster population aging tend to adopt automation technologies more rapidly, helping to offset the decline in the working-age population and maintain productivity.

To reduce the economic impact of population aging, many governments are promoting policies such as extending working lives, encouraging greater participation of women and older adults in the workforce, and investing in technology and skills development. While population aging presents significant economic challenges, appropriate policies and technological innovation can help societies adapt to demographic change and support sustainable economic growth.
