Excerpt:
A substantial theoretical and empirical economic literature argues that institutions are the primary determinant of long-run economic outcomes. The paper offers a brief introduction to the institutions literature and presents two case studies focusing on sets of major institutional reforms that pulled billions out of extreme poverty: India and China. We discuss the potential areas for reform in a charter city and the widespread success of special economic zones and other projects like charter cities.
Finally, we make an initial effort at quantifying the cost-effectiveness of charter cities. Although the model is relatively simplistic, it allows for direct comparison between GiveWell’s top charities and the Charter Cities Institute. Our modeling suggests that a single charter city could be as effective as Deworm the World, GiveWell’s top charity, within 50 years. Under a set of optimistic but not unreasonable assumptions, a charter city could be over 40 times as effective as Deworm the World.
The evidence for the importance of growth is weaker than RCTS by its nature. We're mostly relying on arguments from authority and the eye test. Most economists agree that institutions matter. Shenzhen before and after SEZ status gives an idea of the potential upside. I think most economists would be sympathetic to our high, med, and low estimates of growth.
Very pessimistic is 0, and very optimistic is 5+%, but we bounded our estimates
