摘要

我建立了一个世界经济生产网络模型，其特点是品种的超越对数（又称转化对数）聚集器。这就产生了可变的替代弹性，这种弹性与国家-部门层面上每个出口商的进口商支出份额成反比，这与证据一致。我使用 19 个经合组织经济体和 30 个行业 1970-2018 年的数据对模型进行了量化。与类似的恒定弹性模型相比，我发现转换模型放大了主要贸易伙伴之间的国际冲击传导，削弱了其他地方的传导，这在一定程度上解决了 "贸易联动之谜"。

The network origins of trade comovement

I develop a production network model of the world economy that features Transcendental Logarithmic (a.k.a. translog) aggregators of varieties. This gives rise to variable substitution elasticities that consistent with the evidence are inversely related to the importer expenditure shares per exporter at the country-sector level. I quantify the model using data for 1970–2018 from 19 OECD economies and 30 sectors. Compared to the analogous constant elasticity version of the model, I find that the translog model amplifies international shock transmission between major trade partners and attenuates transmission elsewhere, which to an extent resolves the “trade comovement puzzle”.

期刊介绍： The Journal of International Economics is intended to serve as the primary outlet for theoretical and empirical research in all areas of international economics. These include, but are not limited to the following: trade patterns, commercial policy; international institutions; exchange rates; open economy macroeconomics; international finance; international factor mobility. The Journal especially encourages the submission of articles which are empirical in nature, or deal with issues of open economy macroeconomics and international finance. Theoretical work submitted to the Journal should be original in its motivation or modelling structure. Empirical analysis should be based on a theoretical framework, and should be capable of replication.
