Countries are in a high-stakes competition to develop AI talent and respond to the technology's transformative impact on labor markets and economic growth. As the race intensifies, a critical question looms large: What talent development strategies deliver proven outcomes?

In a recent book published by Stanford University Press, The Four Talent Giants, Stanford sociologist Gi-Wook Shin, a senior fellow at the Freeman Spogli Institute for International Studies, examines how countries attract, develop, and retain talent in a globalized world. Shin, who is also the William J. Perry Professor of Contemporary Korea and director of the Korea Program at the Shorenstein Asia-Pacific Research Center (APARC), explores how four vastly different Asia-Pacific nations – Japan, Australia, China, and India – rose to economic prominence by pursuing distinct human resource development strategies, encompassing different approaches to education, migration, and transnational talent mobility.

The study provides a framework that extends beyond the four cases, offering policy lessons for other economies, particularly less developed nations. Below are four insights from the book on the evolution of talent strategies and why countries need to construct multiple forms of talent – domestic, foreign, and diasporic – to address new risks and capitalize on emerging opportunities.

1. Look for variation in mobilizing human resources for development

Several Asia-Pacific countries now rank among the world’s largest economies – a marked shift from the 1980s, when Japan was the only regional economy near the top. Shin cautions against interpreting this rise of Asia-Pacific nations as evidence of a single developmental regional “recipe.” Instead, his work shows that similar economic outcomes emerged from different national paths, shaped by distinct histories of colonial rule, nationalism, state-building, and higher education policy.

Rather than isolating one driver of growth, the analysis highlights how states structured education systems, migration pathways, and global connections to talent in ways that reflected domestic priorities and constraints.

2. Talent includes social capital, not just skills or credentials

Shin defines talent broadly as both human capital and social capital. In a transnational era, the value of talent lies not only in technical expertise but also in the networks, relationships, and institutional ties that connect individuals across borders.

This insight underpins a four-part framework for national talent strategies: brain train (developing domestic talent), brain gain (attracting foreign talent), brain linkage (maintaining ties with citizens and students abroad), and brain circulation (sending talent out and facilitating return). Successful countries rarely rely on a single approach; instead, they combine these strategies in different proportions over time.

3. Talent strategies must be diversified and rebalanced over time

A central contribution of Shin’s book is a framework he calls Talent Portfolio Theory, which likens national talent strategies to investment portfolios. Just as investors diversify assets and rebalance them as conditions change, states must continually adjust how they train, attract, and retain talent in response to economic shifts.

Japan’s experience illustrates both the strengths and limits of a concentrated strategy. Its post-WWII success rested on a robust domestic training system spanning universities, vocational schools, and workplace education. Nevertheless, as the global knowledge economy evolved in the 1990s, Japan struggled to adapt, facing demographic decline and hampered by institutional introspection. Only in the 2010s did Japanese policymakers begin to diversify talent development through study-abroad programs, attracting international students, and implementing limited immigration reforms.

Australia followed a contrasting path, relying heavily on foreign talent through skilled migration and international education. Its system emphasized work-migration pathways and relatively easy naturalization for international students, while more recent policies have focused on sustaining global alumni and diaspora networks. Each model carries risks, but together they demonstrate why diversification and timely rebalancing matter.

4. Political leadership and state policy shape talent outcomes

Across cases, Shin argues that talent strategies are not purely organic market outcomes. Political leadership and state capacity play decisive roles in shaping higher education systems and migration policy. China’s post-reform experience demonstrates how state-led overseas training and return programs helped address the loss of scientific expertise after the Cultural Revolution. Over time, China shifted from emphasizing the return of Chinese nationals to the country toward building broader transnational linkage and circulation mechanisms.

India offers a different model, where long-standing patterns of outward migration produced a global diaspora that functions as a form of “brain deposit.” Alumni of Indian Institutes of Technology and other elite institutions now serve as transnational bridges connecting India to Silicon Valley and other innovation hubs.

For developing countries, Shin offers a counterintuitive lesson: initial brain drain is often unavoidable and can be productive if governments invest in long-term linkage and circulation rather than restricting mobility. To the United States and other nations grappling with anti-immigration politics, Shin’s message is that erecting barriers to attracting and retaining global talent could undermine their long-term economic competitiveness.

What have been some of the most challenging aspects of conducting research in this field, and how did you overcome these challenges? 

Early on, one of the major challenges was finding a place with the right kind of support: interested colleagues, staff who could assist with fieldwork, and, especially, a community of graduate students interested in similar questions. That kind of environment takes time to build. Oxford had a very strong community with a lot of support, funding, and students working in this area. When I later returned to Stanford, we hired younger development economists and were able to build a similarly vibrant student community working on different aspects of behavior and development.

How do you see your research influencing policy or contributing to real-world change? 

Mostly through understanding behavior and what lies behind different types of decisions. That’s what matters. In addition, the direct policy impact has largely come through my students. Many have gone into academia, but many others have joined organizations like the World Bank, the IMF, or private companies. One student, for example, helped set up a commodity exchange in Ethiopia, which certainly had policy impact. So my influence on policy has been felt primarily through the work that my students go on to do.
 

How have things changed in your field since you first began your research, and how has this influenced the way you approach your work? 

Research methodologies have evolved significantly over time. In the early days, researchers did not even use surveys. Later, surveys became more rigorous, and the field moved toward panel data to follow households over longer periods. With the introduction of GPS, it became possible to work with spatial data in new and more precise ways. The emergence of randomized controlled trials marked another major shift and shaped development economics for many years, although that influence is now starting to decline. Conceptually, the growing importance of behavioral economics has also been a major change and has become increasingly central to how we study issues in economic development.

What gaps do you feel need to be addressed in your research field, and what do you anticipate you will study more in the future? 

There are always gaps. It never is a finished business. The challenges also change over time. Recently, in a very short period, many things built over our lifetimes have been undone. The question is whether to try to rebuild them or conclude that they did not work and try something else. I do not think many of the solutions being proposed now will last; they are not effective. The erosion of the rule of law is especially disturbing. Even democracies struggle with it, but in this country, it has essentially gone out the window. The neglect of international law is also profoundly shocking.

Could you elaborate on the broader shifts you’ve observed in recent years, especially the weakening of institutions and systems that once supported development and international cooperation? 

Closing down USAID is a massive change. Development institutions could certainly be improved, but shutting them down entirely is something very different. These shifts have also affected research funding. Funding has dwindled, and academic positions in development have declined. The job market in development economics overall seems to be shrinking. There is also less interest in people who study democracy, because their work would necessarily be critical of what is happening. It has been a significant backward step.

In times of uncertainty, what gives you hope for the future of your field? 

My students! Their enthusiasm has not disappeared, and the enthusiasm among researchers remains strong as well. Our international contacts remain solid, and parts of the world, especially in Europe, such as Germany and Switzerland, have not given up on these ideals. For example, Esther Duflo recently moved from MIT to Zurich, and we may see more moves like that.

Lastly, what book would you recommend for students interested in a research career in your field? 

Development economics now covers everything; it’s essentially all economics for 80 percent of the world, so there isn’t one book that summarizes it. If someone wants to start a research career focused on market institutions, I would recommend the book I wrote on that topic: Market Institutions in Sub-Saharan Africa: Theory and Evidence (MIT Press, 2003). But if I had to pick a book I personally enjoyed, it would be the historian Fernand Braudel's three-volume Civilization and Capitalism, which looks at market institutions across the world from 1400 to 1800. It was eye-opening and a lot more interesting than traditional, battle-focused history.
 

As he approaches retirement at the end of 2025, Dr. Fafchamps offers insights drawn from decades of research on behavior and institutions. His legacy endures through his students and the body of research that continues to shape scholarship worldwide.

On November 14, 2025, CDDRL and the King Center on Global Development hosted "Unfinished Business: A Tribute to Marcel Fafchamps" — a full-day academic symposium celebrating the career and contributions of economist Marcel Fafchamps on the occasion of his retirement. Featuring a keynote by Marcel himself, this tribute brought together colleagues, collaborators, and students to engage with the themes and ideas that have shaped his influential work in development economics, labor markets, and social networks.
