Abstract
Why do policies yield uneven returns across institutions? I examine this question through a principal-agent model of education policy under asymmetric information. I show that the optimal second-best policy must accept a trichotomy of compliance: low-capacity schools rationally under-comply, intermediate schools bunch at the mandate, and high-capacity schools over-comply. Mandates and enforcement operate on distinct margins—mandates shift the entire compliance distribution while enforcement exclusively targets under-compliers. Extending to a dynamic setting, I demonstrate that lack of commitment triggers a ratchet effect where high-capacity schools strategically suppress effort to avoid stricter future mandates. The optimal response is policy gradualism: regulators dampen updates to preserve long-term incentives. These results provide a structural foundation for designing adaptive regulatory systems under institutional heterogeneity.
