Item Non-Response to Financial Questions in Household Surveys: An Experimental Study of Interviewer and Mode Effects.

We analyse the determinants of non-response to questions on financial items such as income and asset holdings in household surveys. Our data come from a controlled field experiment. As part of the SAVE study – a representative survey conducted in Germany in 2001 – questions on household income and financial assets were administered using different modes (personal interview versus drop-off questionnaire). The data also allow us to investigate the influence of interviewer characteristics on non-response. Our results are in line with predictions derived from models of survey response behaviour that have been developed in survey research and social psychology. [ABSTRACT FROM AUTHOR]
