Brain drain or economic gain? Untangling the global migration-growth puzzle through causality and time-frequency lenses
(Elsevier, 2025-07-22) Dissanayake, P.; Chloe, L; Azmi, Y; Landersz, S; Jayathilaka, R
This study investigates the complex causal relationships between net migration and economic growth at the global, income group, and country levels, framing these dynamics within the evolving landscape of global economic integration and disparities, thereby addressing the enduring “brain drain or economic gain” debate. The analysis is conducted employing the latest available panel data from 1990 to 2023 for 154 countries. Additionally, several advance analytical techniques including Juodis, Karavias and Sarafidis non-causality test and Wavelet Transform Coherence is utilised to investigate relationships across multiple scales and time frequencies. To the best of the authors’ knowledge, no prior research has examined these dynamics using these methods. Additionally, a novel visualisation technique called Lucius Jesper Chloe heatmap, was utilised to depict the Granger causalities. The findings confirm a relationship between migration and economic growth on a global scale. Further analysis reveals bidirectional and unidirectional relationships within income groups and countries. Finally, implications are made for policymakers to develop economic policies that leverage the economic potential of migration and vice versa.

Mapping causal relationships between migration and economic growth: A visual and empirical approach
(Elsevier, 2025-09-17) Azmi, Y; Landersz, S; Dissanayake, P; Chloe, L
The focus of this study is to identify whether causal relationships exist between migration and economic growth across countries in the Asian continent. Real GDP per capita and net migration per capita were used to measure economic growth and net migration, respectively. A dataset comprising panel data from 1994 to 2023, covering 41 countries, was utilised. The Bootstrap Dumitrescu and Hurlin Granger non-causality test was conducted for a continental analysis of Asia. Further, the Granger causality Wald test was undertaken for in-depth country-level analysis. The empirical results indicate a unidirectional causality in Asian continent, and Eastern, and Western Asian sub reigns while other sub reigns indicated no causality. Additionally, while majority of the countries indicated no causality, seven countries namely, Saudi Arabia, Turkmenistan, Viet Nam, Sri Lanka, Macao SAR China, Malaysia and Rep. Korea indicated unidirectional causalities. Based on these findings, implications were made for policymakers when developing economic policies that leverage the economic potential of net migration.
