Sample surveys routinely ask for respondent consent to link survey information with administrative databases, but not all survey units agree to the linkage. Efforts to study whether placement of the linkage consent question influences consent have been undertaken. However, these studies have only been performed in interviewer-administered household surveys. Whether placement matters in self-administered modes (e.g., web) and for other types of target populations remains an open question. We present results of a placement experiment in a web survey of establishments in Germany and offer insights and contribute to “best practice” guidelines for maximizing linkage consent.
