Abstract

This article examines the relationship between skill mismatch and the economic returns to science, technology, engineering, and mathematics (STEM) versus non-STEM degrees in Cambodia. Using an integrative literature review grounded in human capital theory, signaling theory, and the assignment model, it synthesizes evidence from national labor surveys, international development reports, and emerging Cambodian scholarship. The review finds that STEM graduates earn a modest wage premium in formal employment, but that a large informal sector, a narrow industrial base, and weak quality assurance compress this premium well below theoretical predictions. Non-STEM graduates, especially in education, law, and the social sciences, face severe overeducation and horizontal mismatch yet continue to enroll. The article concludes that reform must simultaneously address graduate supply and the economy’s absorptive capacity, and offers recommendations for the Ministry of Education, Youth and Sport, universities, and private-sector stakeholders.
