Cost-Quality Trade-offs in Web Surveys: Finding the Right Balance
1Institute for Employment Research (IAB), Germany; 2University of Mannheim, Germany
Web surveys continue to be a pervasive mode of data collection in the social sciences. Not only are web surveys considered to be cost-effective, they also offer many attractive measurement capabilities that allow for a rich and detailed measures to be collected. However, there is an ongoing debate about whether and when web surveys produce reliable estimates of a given target population, and whether more expensive web survey methods yield more reliable results compared to cheaper ones.
In this talk, I will discuss this debate and highlight empirical examples of cost-quality trade-offs that web surveys face. In addition, I will point to opportunities where mixing cheaper and more expensive web survey methods might lead to improved data quality at a reduced cost.
