American Exceptionalism as a Problem in Global History
通过比较美国与英国、埃及、印度的工资和价格，研究美国19世纪工业化需要关税保护的原因，以及1895年后生产率提升如何改变其比较优势，并解释埃及和印度为何无法复制美国政策。
The causes of the United States’ exceptional economic performance are investigated by comparing American wages and prices with wages and prices in Great Britain, Egypt, and India. American industrialization in the nineteenth century required tariff protection since the country's comparative advantage lay in agriculture. After 1895 surging American productivity shifted the country's comparative advantage to manufacturing. Egypt and India could not have industrialized by following American policies since their wages were so low and their energy costs so high that the modern technology that was cost effective in Britain and the United States would not have paid in their circumstances.
