This report considers the ways in which political economy analysis can be used to understand the drivers, dynamics, and implications of displacement for development processes. It argues that political and economic interests guide political will, including commitments to uphold the Guiding Principles on Internal Displacement, the Responsibility to Protect and the InterAgency Standing Committee Framework on Durable Solutions. The report provides a synthesis of empirical research carried out through four case studies in Sudan and also Bangladesh, El Salvador and Iraq.
