Summary: | Past research has found that subjective
questions about an individuals' economic status do not
correspond closely to measures of economic welfare based on
household income or consumption. Survey respondents
undoubtedly hold diverse ideas about what it means to be
"poor" or "rich." Further, this
heterogeneity may be correlated with other characteristics,
including welfare, leading to frame-of-reference bias. To
test for this bias, vignettes were added to a nationally
representative survey of Tajikistan, in which survey
respondents rank the economic status of the theoretical
vignette households, as well as their own. The vignette
rankings are used to reveal the respondent's own scale.
The findings indicate that respondents hold diverse scales
in assessing their welfare, but that there is little bias in
either the economic gradient of subjective welfare or most
other coefficients on covariates of interest. These results
provide a firmer foundation for standard survey methods and
regression specifications for subjective welfare data. |
