Dreaming big? Self-valuations, aspirations, networks and the private-school earnings premium
利用1970年英国队列研究数据，发现私立学校通过提升内控点、志向和社交网络（而非自尊）影响42岁收入，但这些因素只能解释收入溢价的一小部分，大部分溢价源于教育成就。
An important axis of inequality in Britain is the private/state school divide. The success of private schools in Britain in delivering high academic achievements and better-paid jobs has been attributed to these schools engendering high self-evaluations, greater aspirations and social networks. Using recently repaired data on secondary school type from the 1970 British Cohort Study, we find that internal locus of control, aspirations and access to networks, but not self-esteem, are raised by private schooling. Locus of control and aspirations (but not networks or self-esteem) each have modest effects on earnings at age 42. Yet only a small part of the private school earnings premium is accounted for by all these factors. Much of the premium is due, rather, to educational attainments. This evidence suggests that strategies to strengthen self-evaluations or aspirations in state schools will contribute little on their own to the objective of greater equality or social mobility.
