6.Conclusions
In this paper,we present a model of trade and unemployment,in which unemployment is search induced and trade arises as a result of Heclscher-Ohlin (H-0) comparative advantage based on differences in factor proportions and/or Ricardian comparative advantage based on relative technological differences.We also discuss comparative advantage arising out of intersectoral and international differences in search frictions,efficiency and intensity.Our cross-sectional results provide fairly strong evidence for the steady-state prediction arising when trade is primarily driven by Ricardian comparative advantage:protection increases unemployment rates both across countries.This relationship is robust to controlling for employment laws,trade union power,civil liberties,country and labor force size.Resolving endogeneity concerns through the use of instrumental variables estimation leaves our results qualitatively unaffected.When we consider permanent trade liberalization episodes,we observe an immediate rise in unemployment; in the longer-term our estimates imply a reversal of this rise and an eventual decline in unemployment in the steady state.Overall,we find a striking difference in the short versus long-run responsiveness of unemployment to trade liberalization.Finally,there is only weak and non-robust evidence for the Heclscher-Ohlin proposition which states that the impact of trade policies on unemployment is conditional on whether the country is labor abundant or capital abundant.We interpret this as the offsetting of the Heclscher-Ohlin type composition effects by Ricardian-type productivity-related effects,rather than the complete absence of the former.

6.结论
在本文中,我们目前的贸易和失业,其中失业是搜索诱导和贸易作为Heclscher结果俄林（高- 0）的比较优势的基础上产生的要素比例和/或李嘉图的比较优势模型的基础上的分歧相对的技术差异.我们也讨论的比较优势在搜索所产生的摩擦,提高效率和强度间和国际分歧了.我们的横断面结果提供了相当有力的稳定状态时因贸易主要由李嘉图的比较优势驱动预测：无论是在整个国家的保护失业率上升的证据.这种关系是良好的就业法律控制,工会的权力,公民自由,国家和劳动力规模.通过使用工具变量估计内生性问题解决的结果定性留下影响.当我们考虑永久性正常贸易的自由化时期,我们观察到,失业率立即上升,在长期的估计意味着对这一上升和失业率的稳定状态,最终下降的趋势.总的来说,我们发现在短期与长期失业的贸易自由化反应明显的差别.最后,只有微弱和非有力的证据的Heclscher俄林命题其中指出,对失业率的贸易政策的影响是该国是否是有条件的劳动和资本充足丰富.我们解释为抵消了Heclscher俄林型结构影响的李嘉图式的生产力有关的影响这一点,而不是前者完全没有.
