Can Survey Participation Alter Household Saving Behaviour?
研究发现，参与退休需求详细问卷的家庭非住房储蓄率下降了3.5个百分点（基准为1.5%），表明调查本身可能作为显著性冲击影响家庭财务决策，对调查设计者和行为经济学研究有重要启示。
We document an effect of survey participation on household saving. Identification comes from random assignment to modules within a population-representative Internet panel. The saving measure is based on linked administrative wealth data. Households that responded to a detailed questionnaire on needs in retirement reduced their non-housing saving rate by 3.5 percentage points, on a base of 1.5%. The survey may have acted as a salience shock, possibly with respect to reduced housing costs in retirement. Our findings present an important challenge to survey designers. They also add to the evidence of limited attention in household financial decision making.
