We revisit the Heckscher-Ohlin-Samuelson model in the presence of labor market frictions à la Mortensen-Pissarides. Relaxing the assumption of the oneworker-one-firm matching rule, we show that the Stolper-Samuelson theorem and the Rybczynski theorem may not hold in specific circumstances. We also demonstrate that the Factor Price Equalization theorem is only valid for capital and unemployed labor across countries, but not for employed labor. In equilibrium, trade patterns are determined by countries’ factor endowments and relative factor intensities in sectors (independent of factor intensities in production). Finally, our results suggest an additional explanation for the “missing trade” phenomenon.

我们回顾了赫克舍尔-奥林-萨缪尔森模型中存在的劳动力市场摩擦，就像摩顿森-皮萨里季斯。放松“一个工人一个公司”匹配规则的假设，我们证明了斯托尔珀-萨缪尔森定理和莱布琴斯基定理在特定情况下可能不成立。我们还证明了要素价格均衡定理只对资本和失业劳动力有效，而对就业劳动力无效。在均衡状态下，贸易模式由国家的要素禀赋和部门的相对要素强度(独立于生产要素强度)决定。最后，我们的结果为“贸易缺失”现象提供了一个额外的解释。
