选择偏差的本质是我们没有观察到非最优选择。无论选择变量是离散的还是连续的，这都适用。本文将选择偏差方法推广到选择变量连续且选择集有序的情况。这一分析的主要实际应用是学校选择问题。学校教育被视为一个连续的选择变量和选择校正回报率估计。研究结果表明，选择性是相当重要的，并支持威利斯和罗森的比较优势假说[18]。
The essence of selection bias is that we do not observe nonoptimal choices. This applies whether the choice variable is discrete or continuous. This paper extends the selection bias methodology to the case where the choice variable is continuous and the choice set is ordered. The leading practical application of this analysis is the schooling choice problem. Schooling is treated as a continuous choice variable and selectivity corrected rates of return are estimated. The findings suggest selectivity is of considerable importance and support the comparative advantage hypothesis of Willis and Rosen [18].
