The gap in university enrolment by parental education is large and persistent in many countries. In our representative survey of German adults, 74% of university graduates, but only 36% of those without a university degree, favour university education for their children. The latter are more likely to underestimate returns and overestimate costs of university. Similarly, 75% of adolescents with university-educated parents, but only 51% without university-educated parents aspire to a university degree. Experimental provision of general return and cost information does not close the aspiration gap as treatment effects are at least as strong for individuals with a university background as for those without. Differences in economic preference parameters also cannot account for the educational aspiration gap.

对经济回报和成本的无知是否解释了教育愿望差距？来自成人和青少年的代表性证据

在许多国家，父母教育导致的大学入学率差距巨大且持续存在。在我们对德国成年人的代表性调查中，74% 的大学毕业生，但只有 36% 的没有大学学位的人支持他们的孩子接受大学教育。后者更有可能低估回报并高估大学的成本。同样，父母受过大学教育的青少年中有 75% 渴望获得大学学位，但父母没有受过大学教育的青少年中只有 51%。实验性提供一般回报和成本信息并不能缩小愿望差距，因为对于有大学背景的人来说，治疗效果至少与没有大学背景的人一样强。经济偏好参数的差异也不能解释教育愿望差距。
