Measurement Error in Recall Surveys and the Relationship between Household Size and Food Demand
利用家庭调查设计差异，发现回顾性支出调查中食品支出和预算份额的测量误差与家庭规模相关，这可能解释了贫困国家家庭规模增大时食品需求下降的谜题。
Variation in household survey design and implementation is used to obtain evidence of nonrandom measurement error in recall surveys of household expenditure. These surveys, which are used especially in developing countries, appear to have measurement errors in food expenditures and in food budget shares that are correlated with household size. These correlated errors may be part of the explanation for a puzzling pattern of falling food demand with rising household size in poorer countries.
