“Economic Barriers and Resource Availability: Determinants of Educational Disparities in Southeast Asia” is a research paper that systematically outlines the differences in education levels in Southeast Asia, using Myanmar, Singapore and Indonesia as case studies. With a literature review that links the expectancy disconfirmation theory to education, the paper hypothesizes that HDI and resource accessibility are connected, hence influencing the perceived quality of education. This hypothesis is thoroughly assessed through a combination of primary methods including online questionnaire surveys. As a good education can open countless doors, the paper valuably showcases how structured economic study can improve it --- and gives readers an insight into what they can do to help.
