Surveys are frequently used to evaluate the political economy of reforms, but their specific application to policy-making processes is complicated by several methodological limitations. In this project, we intend to identify specific challenges arising from the use of survey data to evaluate reforms, consider their broader consequences on the inferences we draw about reform processes, and develop a set of best practices aimed at addressing these problems. In particular, we focus separately on issues regarding sample quality, question quality, measuring preferences that change dynamically over time, and preference separability.
