Beschreibung

"This chapter reviews a pair of experiments that examined the effects of mailed survey materials on cooperation rates in an establishment computer-assisted telephone interview survey conducted by the US Bureau of Labor Statistics. It presents three experiments designed to examine efficiencies in data collection. The United States Department of Agriculture National Agricultural Statistics Service experimented with different techniques to increase response to subsets of the population for the US Census of Agriculture. The first experiment varied timing and types of contacts, the second experiment examined the effect of tailored messaging and alternative data collection materials on farms that are likely to respond online, and the third tested targeted communications for potential farms. The chapter provides an overview of an experiment that altered the level of detail of questionnaire instructions and the impact on item nonresponse in the IAB Job Vacancy Survey conducted by the Institute for Employment Research in Germany."
