The Missing Link: The Ricardian Approach to the Factor Endowments Theory of Trade
将所有人际贸易视为李嘉图式的，而国际贸易反映各国要素禀赋，从而在赫克歇尔-俄林与李嘉图模型之间建立逻辑联系，并推导出更简单稳健的贸易、福利和要素支付定理。
This paper views all interpersonal trade as Ricardian, while all international trade reflects each country's factor endowment. The model provides the logical link betwe en Heckscher-Ohlin and Ricardo. The strength of the model is that it allows simpler and more robust theorems about trade, welfare, and fac tor payments. Factor price equalization holds universally and Stolper -Samuelson is not tied to the number of goods or factors. A key resul t is that the old Mill theorem that the small country gains all from trade is incorrect. Trade patterns with three factors and two goods a re completely characterized.
