With Vera Toepoel , and people at NIDI and the German Institiute for Demographic Research we have in 2018 conducted a large experiment to tranfer the Gender and Generations Survey to a push-to-web survey. Several papers will document what we did, and what particular designs worked and did not work.These papers will come out later in 2021, and I may publish some more posts about this design. In this post I want to focus on the role of incentives in push-to-web surveys.
