Abstract
Even small monetary incentives, e.g., a one-dollar bill in a postal invitation letter, can increase the response rate in a web survey. However, in the euro currency area, the smallest amount of monetary incentive for a postal invitation is a five-euro bill, which is costly. As such, we conducted a random experiment with prepaid stamp and postcard incentives as affordable alternatives. We compare the effect of our experimental groups with a control group in terms of response rates, response rates in a subsequent wave, data linkage consent, and data collection costs. Compared with the control group, the postcard incentive has no effect on our outcomes except overall costs. Using a prepaid stamp incentive increases the response rate overall but with different effect sizes for subgroups. We find no effect of stamp incentives on response rates in a subsequent wave or data linkage consent.
期刊介绍：
Field Methods (formerly Cultural Anthropology Methods) is devoted to articles about the methods used by field wzorkers in the social and behavioral sciences and humanities for the collection, management, and analysis data about human thought and/or human behavior in the natural world. Articles should focus on innovations and issues in the methods used, rather than on the reporting of research or theoretical/epistemological questions about research. High-quality articles using qualitative and quantitative methods-- from scientific or interpretative traditions-- dealing with data collection and analysis in applied and scholarly research from writers in the social sciences, humanities, and related professions are all welcome in the pages of the journal.
