Abstract

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.

网络、壁垒和贸易

我们研究了一类具有国际生产网络和任意楔形扭曲（如加价、关税或名义刚性）的灵活贸易模型。我们用微观经济统计数据来描述变量对冲击的一般均衡反应。我们的结果有助于分解实际 GDP 和福利增长的来源，也有助于计算反事实。利用同一套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造成的社会损失，并剖析了考虑分类细节在质量和数量上的重要性。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一个分析工具箱，并有助于弥合计算与理论之间的差距。

期刊介绍： Econometrica publishes original articles in all branches of economics - theoretical and empirical, abstract and applied, providing wide-ranging coverage across the subject area. It promotes studies that aim at the unification of the theoretical-quantitative and the empirical-quantitative approach to economic problems and that are penetrated by constructive and rigorous thinking. It explores a unique range of topics each year - from the frontier of theoretical developments in many new and important areas, to research on current and applied economic problems, to methodologically innovative, theoretical and applied studies in econometrics. Econometrica maintains a long tradition that submitted articles are refereed carefully and that detailed and thoughtful referee reports are provided to the author as an aid to scientific research, thus ensuring the high calibre of papers found in Econometrica. An international board of editors, together with the referees it has selected, has succeeded in substantially reducing editorial turnaround time, thereby encouraging submissions of the highest quality. We strongly encourage recent Ph. D. graduates to submit their work to Econometrica. Our policy is to take into account the fact that recent graduates are less experienced in the process of writing and submitting papers.
