Institutions and Persistence Mechanisms: A Commentary on Daron Acemoglu's 2024 Nobel Prize Lecture

This preprint is a short commentary on Daron Acemoglu’s 2024 Nobel Prize lecture, "Institutions, Technology and Prosperity." The focus is on the lecture’s persistence mechanisms: why extractive institutions can endure even when more inclusive arrangements would raise aggregate welfare. Acemoglu summarizes five persistence channels: (i) hold-up and predation that deter investment and participation; (ii) collapse (or non-development) of state capacity driven by conflict around extractive control; (iii) weakened experimentation and collective knowledge building; (iv) an 'economic losers' mechanism in which elites prefer a larger share of a smaller pie; and (v) a 'political losers' mechanism in which elites resist reforms that threaten future political control. The commentary also highlights the lecture’s 'critical junctures' framing, which explains why these mechanisms amplify divergence during periods of disruption. The appendix provides short, citation-ready excerpts from the lecture that correspond to the persistence mechanisms.
