Does survey recall error explain the Deaton–Paxson puzzle?
利用加拿大的回忆和日记食品支出数据，比较家庭规模对人均食品支出的弹性，发现两种数据中均存在负弹性，表明回忆误差不能单独解释迪顿-帕克森之谜。
Using recall and diary food expenditure data from Canada, we compare estimates of the household size elasticity of per capita food expenditure. In contrast to Gibson (2002), we find negative elasticities in both recall and diary data. This in turn means we find evidence of the "Deaton-Paxson puzzle" in both diary and recall data. Recall error cannot be the sole explanation of the puzzle. (C) 2017 TheAuthors. Published by Elsevier B.V.
