The Yale Research Initiative on Innovation and Scale (Y-RISE) advances research on the effects of policy interventions when delivered at scale. While evaluation techniques for pilot-scale programs are well developed, complexities arise when they contemplate scaling up interventions to create policy change.

Y-RISE identifies and tests promising policy interventions and, as they grow, conducts research on the challenges and implications of scale. They are organized around five research networks on the spillover effects, political economy reactions, and Macro/Growth and Welfare implications of policy interventions, external validity of trial results, and the capacity and demand for policy implementation.

In partnership with NGOs and governments, Y-RISE researchers progressively grow successful programs, devising and employing new techniques to measure the changes induced by scale. Y-RISE produces scholarship, guidance for policymakers, and in the process, facilitates large-scale implementation of tested programs.  A prime example of their work is the No Lean Season program on seasonal migration, developed by Y-RISE Faculty Director Mushfiq Mobarak.
