Welcome to the 14th edition of Newsletter Basque Macroeconomics 5.0 published by Web 2.0: Basque Economics Worldwide Leadership
The latest issue of the IMF's Finance & Development (F&D) magazine discusses productivity through various articles. With permission from the authors, I will provide a brief summary of some of the key issues addressed in the text.
Productivity is the engine driving economic growth and social well-being in the modern world. However, in recent decades, there has been a noticeable slowdown in productivity growth rates in many advanced economies, including the United States. This trend has raised concerns among economists and policymakers, as stagnant productivity threatens to halt global economic progress, increase inequality, and undermine social well-being. As economies struggle to adapt to new technological and social paradigms, it is essential to analyze the factors contributing to this slowdown and how technological innovations, such as artificial intelligence (AI) and remote work, might offer a way to revitalize growth.
This article explores the factors behind the productivity slowdown, the impacts of market concentration and stalled innovation, and how new technologies and forms of work could offer a solution to restore global economic dynamism.
The Decline in Productivity: A Global Issue
Productivity growth has been a central element of economic development since the Industrial Revolution. For much of the 20th century, advanced economies experienced robust productivity growth rates, contributing to rising incomes and improved living standards. However, since the mid-2000s, these rates have notably decreased, particularly in the United States, traditionally a leader in innovation and economic growth. From 1947 to 2005, U.S. labor productivity grew at an average annual rate of 2.3%, but since 2005, that rate has dropped to 1.3% annually. Although this difference may seem small, the implications are enormous: had the previous rate been maintained, the U.S. economy would have produced $11 trillion more in goods and services between 2005 and 2018.
This decline is not unique to the United States; other advanced economies, such as Europe and Japan, have also seen their productivity rates fall. Europe, for example, has lagged behind the U.S. in terms of GDP per capita due to stagnant productivity. This slowdown poses a fundamental challenge: what factors have contributed to this decline, and how can they be addressed to revitalize economic growth?
Factors Behind the Productivity Stagnation
One of the key factors behind productivity stagnation is the decline in "creative destruction," a concept coined by economist Joseph Schumpeter. Creative destruction refers to the process by which new companies and technologies replace old ones, driving innovation and growth. However, in recent decades, this process has slowed, particularly in the U.S., where the rate of new business creation has fallen from 13% in 1980 to 8% in 2018. This has resulted in greater market concentration, with larger, older companies dominating key sectors of the economy.
This market concentration not only reduces competition but also limits the ability of smaller, newer companies to innovate. Large companies, by consolidating their market positions, focus more on protecting their dominance than on developing new technologies or improving efficiency. This phenomenon has led to what economist Ufuk Akcigit calls the "innovation paradox": despite a significant increase in research and development (R&D) spending, innovation and productivity have not grown at the same pace. Instead of fostering competition, many large corporations use their R&D spending to create barriers to entry for smaller competitors, utilizing patents and other legal mechanisms to maintain their market position.
Additionally, the slowdown in population growth and aging demographics in many advanced economies have reduced economic dynamism. With fewer young people entering the workforce and a higher proportion of the population at retirement age, economies' ability to generate new businesses and technologies has diminished, contributing to productivity stagnation.
The Promise of Innovation: Artificial Intelligence and New Technologies
Despite the productivity slowdown, technological innovation remains one of the greatest hopes for revitalizing economic growth. Among the most promising emerging technologies, artificial intelligence (AI) stands out as a key tool for improving efficiency and productivity across all sectors of the economy. If properly implemented, AI has the potential to automate routine, repetitive tasks, freeing up workers to focus on more creative, high-value activities.
Nobel laureate Michael Spence argues that AI could be a key driver of global productivity, provided it is adopted inclusively and widely. This means that the technology must be available not only to large tech corporations but also to small and medium-sized enterprises, which drive much of the innovation. If AI is restricted to a few tech giants, its impact could be limited and exacerbate economic inequalities. However, if distributed equitably, AI could improve productivity in sectors as diverse as manufacturing, agriculture, healthcare, and financial services.
AI’s impact goes beyond task automation. It also has the potential to transform how businesses operate, allowing them to scale more rapidly and operate more efficiently. The key, according to Spence, is ensuring that the benefits of AI are accessible to all companies and workers, not just a technological elite.
Barriers to the Adoption of New Technologies
Despite the potential of AI and other emerging technologies, there are significant barriers to their widespread adoption. One of the main challenges is the ability of smaller companies to access these technologies. As Akcigit notes, many large corporations use their market power to limit the diffusion of new technologies, creating an environment in which smaller companies struggle to compete.
Moreover, the initial cost of implementing new technologies can be prohibitively high for many companies, especially in traditionally less tech-intensive sectors such as agriculture or manufacturing. To overcome these barriers, governments and institutions must play an active role in creating a regulatory environment that promotes the equitable adoption of AI and other technologies. This could include tax incentives, grants for R&D, and training programs for workers.
The Impact of Remote Work on Productivity
One of the most surprising trends to emerge in recent years is the rise of remote work, accelerated by the COVID-19 pandemic. According to Nicholas Bloom, remote work has been an unexpected "blessing" for productivity. Despite initial concerns that working from home could reduce efficiency, many companies have found that remote work has improved productivity by lowering operational costs and allowing employees to better manage their time.
Remote work has allowed companies to access a broader talent pool, as they are no longer constrained by geography. This has been particularly beneficial for companies operating in technology or creative sectors, where flexibility and global collaboration are essential for innovation. Additionally, remote work has improved job satisfaction, as many employees enjoy greater autonomy and a better work-life balance.
However, Bloom warns that remote work is not without challenges. Employee isolation and the lack of informal interactions could affect creativity and collaboration in the long term. To mitigate these risks, he suggests that companies adopt hybrid work models that combine the best of remote work with the benefits of in-person interaction. This hybrid approach could offer a balanced solution, maximizing the benefits of remote work while minimizing its downsides.
Reforms to Revitalize Productivity
While technological innovation and new forms of work offer a partial solution to the productivity stagnation problem, broader structural reforms are also needed to address the underlying causes. Nan Li and Diaa Noureldin argue that one of the main causes of low productivity is the misallocation of resources within economies. In many economies, resources are allocated inefficiently, meaning that less productive companies continue to operate, absorbing capital and labor that could be used more effectively elsewhere.
To correct this inefficient allocation, Li and Noureldin propose reforms that encourage greater competition and reallocate resources toward more productive companies. This includes eliminating subsidies that distort markets, reducing regulatory barriers that prevent the entry of new companies, and supporting the creation of new businesses in innovative sectors. Additionally, they suggest that governments should focus on improving access to financing for small businesses and promoting policies that incentivize disruptive innovation.
Conclusion: The Future of Productivity
Productivity is fundamental to global economic growth and well-being, but it has experienced a worrying slowdown in recent decades. Factors such as market concentration, declining business dynamism, and resource misallocation have contributed to this stagnation. However, technological innovation, particularly in the realm of artificial intelligence, and new forms of work like remote work, offer an opportunity to revitalize productivity.
Achieving sustained growth requires an integrated approach that combines the adoption of new technologies with structural reforms that promote competition and improve resource allocation efficiency. At the same time, governments must play an active role in ensuring that the benefits of technological innovation are distributed equitably, creating an environment where both large and small businesses can thrive.
The future of productivity will depend on our ability to harness the potential of technology and adapt our economic policies to a constantly changing world. Only through a balanced approach can we restore economic dynamism and ensure sustainable long-term growth.
