Heterogeneous Economic Returns to Post-Secondary Degrees: Evidence from Chile
利用智利行政数据，分析高等教育学位的经济回报，发现平均回报为正但存在显著异质性，未观测能力甚至导致部分学位回报为负。
We analyze the economic returns to post-secondary degrees in Chile. We posit a schooling decision model with unobserved ability, degree-specific tuition costs, and earnings. We use administrative records to carry out our empirical analysis. Our results show positive average returns to post-secondary education, especially for five-year degrees. However, we also uncover significant heterogeneity. We document how unobserved characteristics (ability) determine the economic benefits of first- and second-best choices, even leading to negative returns to post-secondary degrees. Our findings illustrate the importance of allowing for heterogeneous treatment effects and individuals' choices when examining the returns to education.
