Abstract
We show that when the effectiveness of private tutoring (PT) exceeds a PT-effectiveness threshold, poor families become disadvantaged in sending their children to college and, thus, inequity arises. At the same time, the average spending on PT of the poor families is smaller than that of the wealthy families. Tax and transfer policies are able to amend the inequity, but student loans for college tuition and more establishments of colleges may have limited effects on reducing inequity.
