The Industrial Revolution in Miniature: The Spinning Jenny in Britain, France, and India
研究了珍妮纺纱机为何只在英国被采用并引发工业革命，发现英国工资相对资本价格异常高，使得珍妮机在英国有利可图，而在法国和印度则不然，这解释了工业革命的地域差异。
The spinning jenny helps explain why the Industrial Revolution occurred in Britain rather than in France or India. Wages were exceptionally high relative to capital prices in Britain, so the jenny was profitable to use in Britain but not elsewhere. Since it was only profitable to use the jenny in Britain, that was the only country where it as worth incurring the costs of developing it. Irrespective of the quality of their institutions or the progressiveness of their cultures, neither the French nor the Indians would have found it profitable to mechanize cotton production in the eighteenth century.
