Item nonresponse is a common issue in surveys. We implement an experiment to reduce nonresponse to income questions in an international household survey, looking at four different countries. Survey respondents are asked to report their exact household income. We randomize those who refuse to answer into two groups. In a follow-up question, the control group is asked to choose their income from a...

Fast online surveys without sampling frames are becoming increasingly important in survey research. Their recruitment methods result in non-probability samples. As the mechanism of data generation is always unknown in such samples, the problem of non-ignorability arises making vgeneralisation of calculated statistics to the population of interest highly questionable. Sensitivity analyses provide a ...

This paper investigates how the number of brackets and the choice of upper cutoffs in grouped data affect the metric approximation of income and wealth. The literature currently lacks a definition of what should be considered too few brackets or too-low cut-offs. Using German survey data, we show that more than six (eight) brackets and an upper cut-off at the 95th (97th) percentile are sufficient to ...
