APARC Research - Talent Flows, Brain Hubs, and the Socioeconomic Development in Asia

Talent Flows and Development
Research Focus
The flow of professional talent, both permanent and temporary, is a prevalent aspect of globalization. High-skilled talent moves across national boundaries in search of better professional and social opportunities, thus generally migrating from less-developed to more-developed societies. Yet not all developed societies are equally attractive to foreign talent, as each country differs in the professional and personal opportunities it offers. These various factors affect each country’s ability to attract and retain talent, which is more mobile than ever. The international distribution of talent is thus highly skewed, and the resources and capacities available to countries to attract, develop, retain, and employ skilled talent vary substantially.
Maintaining and developing a talent pool is crucial for global competitiveness in the global knowledge economy, where mobile talent drives knowledge creation and diffusion. Newfound geopolitical challenges also shape talent attraction and mobility, including burgeoning geopolitical tensions, demographic crises, and the COVID-19 pandemic.
The Talent Flows and Development research track, an extension of the past project Talent Flows, Brain Hubs, and Socioeconomic Development in Asia, examines the high-level talent flows of the Asia-Pacific region and their potential policy implications.
This research is part of the Stanford Next Asia Policy Lab (SNAPL).

New Book
The Four Talent Giants: National Strategies for Human Resource Development Across Japan, Australia, China, and India
By Gi-Wook Shin

We are pleased to share that Gi-Wook Shin's new book, The Four Talent Giants: National Strategies for Human Resource Development Across Japan, Australia, China, and India, is out from Stanford University Press (July 1, 2025).
In a sweeping analysis of talent development strategies, Gi-Wook Shin investigates how these four Asia-Pacific countries achieved economic power and sustained momentum by cultivating, attracting, and leveraging talent in varied ways, reflecting cultural, historical, and institutional differences and responding to risks and challenges such as demographic crises, brain drain, and geopolitical tensions. The book offers invaluable insights for policymakers and is essential for scholars, students, and anyone interested in understanding the dynamics of talent and economic growth in the Asia-Pacific region and beyond.
For more about the book, read our story on the APARC website.
The Four Talent Giants: Interview with Gi-Wook Shin
Watch Shin discuss his new book, lessons from the four Asia-Pacific "talent giants" for other countries, how Trump administration policies jeopardize U.S. innovation, and the risks to U.S. long-term success if it falls behind in the race for global talent.

Toward a Portfolio Theory of Talent Development: Insights from Financial Theory, Illustration from the Asia-Pacific (Gi-Wook Shin and Haley Gordon)
This project proposes Talent Portfolio Theory (TPT) as a new framework for studying human resource development. Drawing on insights from Modern Portfolio Theory in financial investment, TPT views a nation’s talent development as creating a “talent portfolio” composed of four “B”s: brain train, brain gain, brain circulation, and brain linkage.
TPT attends to how a talent portfolio, like a financial one, is diversified to minimize risk, and how diversification can be maintained via rebalancing. As such, TPT provides a framework that captures the overall picture of a country’s talent strategy and offers a lens through which to understand how a country changes or “rebalances” its talent portfolio over time.
We illustrate the utility of TPT with the cases of Japan and Singapore. In both these nations, human resource development was key to their economic rise, but their approaches to diversifying and rebalancing their talent portfolios took different routes, leading to divergent outcomes. We conclude by discussing the theoretical and policy implications of the TPT framework for studying and implementing talent development.
The full study based on this project is published in World Development Vol. 184. See also the related news article on the APARC website, A New Approach to Talent Development.
Rethinking Return Migration: Illustrations from China’s Brain Circulation and India’s Brain Linkage (Gi-Wook Shin and Kelsi Caywood)
Brain drain presents a serious challenge to less developed countries (LDCs), depleting their talent pool and hindering development. However, LDCs can counteract brain drain and regain “lost” human capital by repatriating skilled migrants, thus contributing to national development. The current literature based on the return migration paradigm stresses such repatriation (brain circulation), neglecting how skilled diasporic talent can contribute without permanent return through transnational social capital (brain linkage).
We propose a framework that accounts for both human and social capital offered by skilled diaspora members, treating circulation and linkage as distinctive yet intertwined phenomena. We illustrate the utility of the revised framework through a comparative analysis of India and China. Both these countries have witnessed the world’s largest magnitudes of high-skilled emigration, initially leading to brain drain but later providing developmental assets. China has focused on circulating back its overseas talent, while India has embraced transnational linkage without expecting the permanent return of its overseas talent. In addition, circulation has facilitated linkage in China, whereas linkage has fostered circulation in India.
We highlight our study’s theoretical contribution to migration research and offer policy implications for LDCs facing brain drain.
The Promise and Perils of Brain Circulation: Comparing the Macroeconomic Development of South Korea and the Philippines, Using Talent Portfolio Theory
In the 1960s, the Philippines outpaced South Korea’s economic development. Sixty years later, South Korea is a high-income OECD nation, while the Philippines remains a lower-middle-income country. What can explain this divergence?
Previous studies have approached this question through analyses of state and private business institutional investments or analyses of national “human resource” outcomes, including human and social capital. Nevertheless, there has been little synthesis between top-down (institutional) and bottom-up (human resource) perspectives.
This study applies the Talent Portfolio Theory (TPT) to comprehensively compare the macroeconomic development of the Philippines and South Korea in terms of institutional investments and human resource outcomes. TPT considers a nation’s talent development strategy a portfolio composed of four domains: brain train, brain gain, brain circulation, and brain linkage. A strong talent portfolio is diversified to minimize risk, and diversification can be maintained via periodic rebalancing.
South Korea and the Philippines rebalanced their talent portfolios in favor of brain circulation in the mid-20th century. Yet their different approaches to brain circulation generated differential long-term human resource returns. South Korea’s brain circulation focused on repatriating highly educated scientists, who drove economic development via technological innovation in domestic industries in the short term and supported state investments in brain train in the long term. The Philippines, by contrast, invested in labor export and the temporary circulation of professional workers. While this strategy has generated financial returns in the form of remittances, the human resource outcomes have been negligible and have not supported long-term economic development.
This study highlights the relationship between institutions and human resource outcomes and emphasizes the interactions between investments in talent development in shaping long-term outcomes.
