Using US data from the National Longitudinal Survey of Youth and following propensity score matching analysis, the study demonstrates that church attendance during youth has significant positive effects on an individual's psychological capital endowments in the form of self-esteem, positive attitude and self-satisfaction during adulthood. Since a higher level of psychological capital is associated with better economic performance, the study further demonstrates that church attendance during earlier years of life affects an individual's future earnings indirectly through its direct effects on his/her psychological capital endowments. The study offers an important policy proposal and recommends further research for its validation.
