Effects of Self-Efficacy on Individual Earnings: A Preliminary Study of the Thai Labor Market
Main Article Content
Abstract
This study estimates the earnings differences in the Thai labor market that are related to workers’ non-cognitive skills by examining the psychological characteristic of self-efficacy. Self-efficacy is defined as a person’s belief in his or her ability to organize and execute courses of action necessary to achieve a goal. The Thai Mental Health Survey measures both basic socio-economic factors and two psychological indicators of self-efficacy and affective state, drawn from 15 items of the Thai Mental Health Indicator. The effect of self-efficacy on an individual’s annual earnings is estimated using both OLS and IV techniques. From the selected sample, the study confirms that the Thai labor market values self-efficacy, even though it is endogenous. Self-efficacy is independent of gender, religion and marital status, and its effect on earnings is unrelated to years of schooling or work experience. Omitting self-efficacy from the model results in underestimation of female earnings, underestimation of earnings in occupations, and overestimation of earnings in the countryside. Self-efficacy likely contributes to additional earnings (such as earnings from overtime and bonuses) made through intense effort, compared with traditional human capital of schooling or work experience. Policy recommendations aimed at improving self-efficacy and areas for further studies are suggested.
