A bounds analysis of school completion rates in Australia
利用澳大利亚青年调查数据，通过边界分析发现官方学业完成率在1992年峰值时被高估，重复计算是主要原因，对教育政策制定者有参考价值。
Abstract Official estimates of school completion rates in Australia increased in the 1980s, peaked in 1992, and fell immediately thereafter before stabilizing. The official estimates were a specific focus of Australian education policy. The decline caused concern at the time. We use data from the Australian Youth Survey (AYS) to gain insight into the behavior of the official estimates. The AYS suffers from nonrepresentativeness, attrition and nonresponse, which means that parameters of interest are not identified. Our bounds analysis is suggestive that school completion was overstated in the official estimates at their peak. Our analysis points to repetition as a key factor in inflating the official estimates.
