Rethinking age heaping again for understanding its possibilities and limitations
本文回应了A'Hearn等人对年龄堆积作为教育指标局限性的质疑，通过实证展示过去十年发展的方法论元素使基于年龄堆积的数理能力研究成为经济史的重要工具。
Abstract A'Hearn, Delfino, and Nuvolari recently argued in this journal that the indicator function of age heaping for education, and numeracy in particular, is quite limited. In contrast, we show empirically that by applying the methodological elements that were developed over the past decade, age‐heaping‐based numeracy research can be an important tool for economic history.
