Previous research finds that college education brings much less difference in returns for individuals from high social origins than for individuals of low socioeconomic status. But without considering qualitative factors of college, it likely omits true underlying mechanism. In this paper, I address this gap by zooming into the qualitative dimension of college and discussing the heterogeneous effect of STEM major on future wages across people of different social origins. This study focuses on individuals who were between 14 and 17 years old in 1979 in NLSY79 dataset. I construct propensity scores indicating the likelihood of selecting STEM major and utilize hierarchical linear model to check the existence of heterogeneous effect on STEM major on wages in 1998, 2002 and 2006. The results show that although there is indeed a trend that people who come from disadvantaged status are more likely to choose STEM major, no statistically significant evidence supports either the positive selection hypothesis or negative selection hypothesis. In other words, the higher probability of selecting STEM major does not necessarily indicate either more difference or less difference in the returning benefits between STEM graduates and Non-STEM graduates, but in general, people who select STEM major can earn more than those who do not.
