Arrested Development? Puerto Rico in an American Century
利用1900至1940年新构建的GDP指数，发现波多黎各在美国直接统治期间人均收入增长显著，且大萧条影响较轻；近年增长放缓部分源于统计假象。
Puerto Rico became an American colony in 1898, achieving self-rule after the Great Depression. The standard view is that Puerto Rican living standards stagnated before the policy changes of the New Deal and it has lost ground on the mainland since the early 1970s. I show these claims are mistaken. Using a new GDP index for 1900 to 1940, I show that income per capita grew at impressive rates during direct American rule and Puerto Rico escaped the worst ravages of the Great Depression. In addition, I find the recent growth slowdown is partly a statistical artifact.
