Effects of Cognitive and Non-cognitive Skills on Earning Outcomes: A Case of Khonkaen Province of Thailand
Main Article Content
Abstract
From the well-known Mincer equation explained years of schooling and
potential training periods as main sources for earnings differential, this study further
analyzes another explanation of earnings in terminology of non-cognitive skills.
Difference in wages in different occupations and genders could be explained by
non-cognitive traits. Signifi cant non-cognitive variables are 1. locus of control 2. self-esteem 3. big fi ve personalities and 4. confl ict management. After adding a non-cognitive skill called “Locus of Control” into the model and comparing without it, the coeffi cients
declined when adding a non-cognitive skill. Unlike cognitive skills, adding non-cognitive measures to the model greatly reduces the explanation by cognitive
skills (years of schooling), experience year, and training hour.
