Testing the General Validity of the Heckscher-Ohlin Theorem
利用日本19世纪中叶从自给自足转向开放贸易的过渡期，检验了赫克歇尔-俄林定理的要素价格表述，发现该定理在历史数据中成立。
We exploit Japan's mid-nineteenth century transition from autarky to open trade to test Alan Deardorff's (1982) seminal and parsimonious autarky price formulation of the Heckscher-Ohlin theorem. Factor price data from Japan's late autarky period impose a refutable restriction on Japan's factor content of trade. Our data are constructed from many historical sources, including a major Japanese survey of agricultural techniques and a rich set of nineteenth century comparative cost studies. Evaluating Japan's factor content of trade during 1865–1876 under alternative theoretical assumptions about technology, we provide robust evidence in favor of the Heckscher-Ohlin hypothesis.
