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 very granular list of brackets, the treatment group receives only three options to choose from. In all four countries, the treatment leads to a significant decrease in nonresponse. Thus, when condensed income data are sufficient, fewer answer options are a cost-effective way to reduce nonresponse.
