Are Pro-productivity Policies Fit for Purpose?

Dear Readers,

Welcome to RIETI Report. This bi-weekly newsletter will keep you updated with the recent columns, event information and research results by RIETI fellows and other leading economists in Japan and around the world.

In this edition, we feature topics related to productivity improvements and related challenges. Slowing growth, once synonymous with Japan, now plagues many countries. In his recent BBL seminar, RIETI Non-Resident Fellow, Professor Bart van Ark, discussed pro-productivity policies. Focusing on G20 countries, he highlighted the importance of addressing both demand- and supply-side issues while considering long-term factors such as geopolitics, aging societies, and emerging technologies in tackling productivity issues.

We hope you will enjoy it. If you have any feedback, we would love to hear from you (news-info@rieti.go.jp).

==============
Today, in many advanced economies - and particularly in Japan - growth in employment and total hours worked has plateaued or even declined. Since GDP growth equals the sum of labor input and productivity gains, future economic growth must now rely almost entirely on productivity improvements. While this trend began to show in Japan several decades ago, it is no longer unique to Japan, as nowadays many European countries are beginning to experience the same structural shift.

At the same time, societies find themselves surrounded by rapid technological progress, with AI being the most recent example, without yet seeing clear productivity gains. This recalls Robert Solow’s famous observation from the 1980s: “We see computers everywhere except in the productivity statistics.” The question now is whether this pattern is being repeated or whether the world is entering a new phase where technology may help address broader issues such as aging populations, climate change, and geopolitical shifts.

Technology also brings challenges, including job disruption and societal risks. It is time to ask whether the productivity policies of the 1980s–2000s remain adequate, or whether a new policy framework needs to be developed.
