Project Description

Summary:  View help for Summary
We present a proof-of-concept for minimalist market design (Sönmez, 2023) as an effective methodology to enhance an institution based on stakeholders’ desiderata with minimal interference. Four objectives – respecting merit, increasing retention, aligning talent, and enhancing trust – guided reforms to the US Army’s centralized branching process of cadets to military specialties since 2006. USMA’s mechanism for the Class of 2020 exacerbated challenges in implementing these objectives. Formulating the Army’s desiderata as rigorous axioms, we analyze their implications. Under our minimalist approach to institution redesign, the Army’s objectives uniquely identify a branching mechanism. Our design is now adopted at USMA and ROTC.
