What T. R. Took: The Economic Impact of the Panama Canal, 1903–1937
研究了巴拿马运河作为当时最大公共投资之一，在运营头十年为美国带来的巨大社会回报，主要来自加州石油运输，并分析了美国如何利用武力威胁从巴拿马政府获得更有利的协议。
The Panama Canal was one of the largest public investments of its time. In the first decade of its operation, the canal produced significant social returns for the United States. Most of these returns were due to the transportation of petroleum from California to the East Coast. The United States also succeeded in leveraging the threat of military force to obtain a much better deal from the Panamanian government than it could have negotiated otherwise. “I took the Isthmus.” President Theodore Roosevelt, 1904 “Why, it's ours, we stole it fair and square.” Senator Samuel Hayakawa, 1977
