This article provides a comparative review of the main theoretical frameworks used to analyze global migration phenomena, offering readers a clear understanding of the academic debates in the field.

A variety of theories have been proposed to explain the complex nature of migration. The article begins by outlining the neo-classical economic model, which emphasizes individual decision-making based on cost-benefit analyses, and contrasts it with the new economics of labor migration, which considers household-level decisions and risk diversification.

Additional theories, such as network theory, are discussed to highlight the role of social ties and diaspora communities in facilitating migration. The article critically evaluates the strengths and limitations of each framework, providing examples of how each theory explains different aspects of migration flows.

By comparing these scholarly frameworks, the article underscores the importance of adopting an interdisciplinary approach to fully understand migration dynamics. It also highlights emerging trends in migration theory, such as the impact of digital connectivity on global migration networks, and concludes with suggestions for integrating these diverse perspectives into future research.
