18 February 2025In this study, we define, categorize, and systematically describe best practices and barriers to implementing preference elicitation lab-in-the-field experiments with farmers based on qualitative, in-depth interviews with researchers from the Research Network on Economic Experiments for the Common Agricultural Policy (REECAP). Following an assessment of the challenges the researchers faced and the solutions they adopted, we provide a step-by-step guide to conducting such experiments. We elaborate on limitations and provide recommendations and suggestions for future research.
