我们研究了一类灵活的贸易模型，其中包含国际生产网络和任意的楔形扭曲，如加价、关税或名义刚性。我们描述了一般均衡的变量冲击的微观统计方面的反应。我们的结果对于分解真实的GDP和福利增长的来源以及计算反事实是有用的。使用相同的一组微观经济充分统计数据，我们还描述了关税和冰山贸易成本增加所造成的社会损失，并剖析了分类细节会计的定性和定量重要性。我们的结果可用于计算近似和精确的反事实，为研究大规模贸易模型提供了分析工具箱，并有助于弥合计算和理论之间的差距。
We study a flexible class of trade models with international production networks and arbitrary wedge‐like distortions like markups, tariffs, or nominal rigidities. We characterize the general equilibrium response of variables to shocks in terms of microeconomic statistics. Our results are useful for decomposing the sources of real GDP and welfare growth, and for computing counterfactuals. Using the same set of microeconomic sufficient statistics, we also characterize societal losses from increases in tariffs and iceberg trade costs and dissect the qualitative and quantitative importance of accounting for disaggregated details. Our results, which can be used to compute approximate and exact counterfactuals, provide an analytical toolbox for studying large‐scale trade models and help to bridge the gap between computation and theory.
