Study Finds Older, Smaller Populations Lift Output per Worker, With No Drag on GDP

Summary
A new paper by Daron Acemoglu, David Autor, Keelan Beirne and Andrew Scott finds aging, shrinking populations historically increased output per worker without reducing overall GDP.
Reduced labor supply appears to push firms and workers toward technology that augments labor, lifting productivity rather than choking off growth.
The findings challenge widespread warnings that falling birth rates will inevitably mean weaker growth and less innovation.
The study adds to a global policy debate as many economies confront lower fertility, older workforces and slower population growth.
Beyond economics, what are the social costs of a future with permanently fewer children and an aging population?
As AI offsets a shrinking workforce, will the resulting wealth be shared or worsen economic inequality?

Overview
This report explores how an aging population, traditionally seen as a drag on economic growth due to a shrinking workforce and changing consumption patterns, is also driving new economic dynamics. As the share of older individuals rises and reduces available workers, industries are increasingly investing in automation and advanced technologies. Recent research shows that demographic differences can explain a significant part of the gap in robot adoption between countries, leading to faster technological innovation and capital deepening. These changes help boost productivity per worker, offering a more nuanced view of demographic decline and its economic impact.
