“The Next Convergence: The Future of Economic Growth in a Multispeed World” by Nobel laureate Michael Spence offers a compelling exploration of global economic shifts, focusing on how developing nations are converging toward the prosperity of developed economies. Spence invites readers to consider how rapid globalization and technological innovation are reshaping the world’s economic landscape, with emerging markets driving a “multispeed” growth environment. At its core, the book grapples with critical questions about sustainability, inequality, and the structural changes that need to occur for both developed and developing countries to thrive in this new economic era.

Spence begins by framing the idea of “convergence,” a process where emerging economies grow faster than their developed counterparts, gradually closing the income and productivity gap. He explores historical examples of countries like Japan and South Korea, which transitioned from developing to developed status by adopting innovative policies and integrating with the global economy. In particular, Spence discusses China and India as key players in this new wave of convergence.

One of the central arguments in this section is that the speed and scale of economic change in developing countries will challenge global governance structures. Spence states, “The world has never before experienced growth of this speed and size,” emphasizing that the rapid pace at which large populations are moving out of poverty will have unprecedented effects on global systems.

Example: China’s transformation from a largely agrarian society into a global manufacturing powerhouse illustrates the convergence process. Spence notes how China’s decision to open its markets, coupled with strategic state planning, enabled it to achieve sustained growth, eventually rivaling the economic power of advanced nations.

As Spence delves deeper into the consequences of this economic transformation, he highlights the growing inequality within and between countries. While convergence is lifting millions out of poverty, it is also creating new challenges in wealth distribution. The rise of the middle class in developing countries contrasts with the stagnation of incomes in developed economies, leading to political and social tensions. Spence warns that, without structural reforms, inequality could undermine the long-term benefits of global growth.

A memorable quote from this section illustrates this point: “Economic growth does not automatically translate into equitable distribution,” he argues, suggesting that countries must actively address inequality through targeted policies. Spence proposes measures such as investing in education, healthcare, and infrastructure to ensure that growth is inclusive.

Example: Spence points to the uneven growth in the United States and parts of Europe, where technological advancements have disproportionately benefited higher-income individuals, while middle- and lower-income groups face stagnating wages. In contrast, countries like Brazil have made significant strides in reducing poverty through welfare programs that redistribute wealth more equitably.

In addition to inequality, Spence emphasizes the sustainability of growth. The environmental costs of rapid industrialization in developing countries pose long-term risks, from resource depletion to climate change. Spence argues that future economic growth must account for these challenges and calls for a global commitment to sustainable development.

A key driver of convergence, according to Spence, is technological advancement. Technology not only enhances productivity but also allows emerging economies to leapfrog traditional stages of development. The digital revolution, in particular, has enabled countries to bypass certain industrial phases and directly engage in global trade and innovation.

Spence discusses how countries like India have become global leaders in technology services, despite lacking a manufacturing base. He argues that technological adoption has the potential to accelerate growth but warns that it also exacerbates job displacement in both developed and developing economies.

In one of the book’s key insights, Spence states, “The future belongs to those who can adapt to technological change,” underscoring the importance of education and re-skilling programs to prepare workforces for the new digital economy.

Example: India’s rise as an IT powerhouse exemplifies how technology can serve as a growth engine. Spence discusses how the country’s investment in education, particularly in STEM fields, allowed it to capitalize on the global demand for software development and outsourcing services, creating a new economic model based on knowledge rather than manufacturing.

Spence dedicates a significant portion of the book to discussing the implications of this multispeed world for global governance. The traditional institutions of global governance—the World Bank, the International Monetary Fund, and the World Trade Organization—were designed in a post-World War II era and are ill-equipped to manage the complexities of today’s interconnected global economy.

He calls for reforms to these institutions, urging them to include the voices and interests of emerging economies. Spence also emphasizes the importance of global cooperation in tackling shared challenges like climate change, financial stability, and trade imbalances.

A memorable quote from Spence illustrates this urgent need for reform: “We live in a world where the decisions made in one country can reverberate across the globe in ways that were unimaginable in the past.” He argues that the future of global economic growth depends on whether countries can work together to create a more inclusive and sustainable global system.

Example: Spence highlights the financial crisis of 2008 as a case study of how interconnected the global economy has become. He explains how the collapse of the housing market in the United States led to a worldwide recession, disproportionately affecting developing countries that were reliant on global trade and investment.

In the concluding chapters, Spence reflects on the future trajectory of global growth, expressing cautious optimism. He acknowledges that the path ahead is fraught with challenges—inequality, environmental degradation, and political instability—but believes that with the right policies and global cooperation, the benefits of convergence can be shared more broadly.

Spence’s vision for the future involves rethinking traditional economic models to embrace innovation and inclusivity. He advocates for continued investment in human capital, sustainable infrastructure, and governance reforms that reflect the new realities of the 21st-century economy.

Impact and Relevance Today: “The Next Convergence” remains highly relevant, particularly as the world continues to navigate the economic disruptions caused by the COVID-19 pandemic.
