摘要

为了量化贸易摩擦，我们考察了多产品出口商。本文建立了一个灵活的一般均衡模型，并利用巴西企业-产品-目的地数据估计了在丰富需求和市场准入成本冲击下的市场进入成本。我们的估计表明，远离企业核心竞争力的额外产品的生产成本更高，但市场准入成本存在实质性的范围经济。市场准入成本因目的地而异，在邻近地区和非关税壁垒较少的目的地，市场准入成本下降得更快。我们评估了一个反事实情景，该情景协调了各目的地的市场准入成本，并发现全球福利收益类似于取消所有现行关税。(jel d22, f12, f13, f14, o14, o19)

The Extensive Margin of Exporting Products: A Firm-Level Analysis

To quantify trade frictions, we examine multiproduct exporters. We build a flexible general-equilibrium model and estimate market entry costs using Brazilian firm-product-destination data under rich demand and market access cost shocks. Our estimates show that additional products farther from a firm’s core competency come at higher production costs, but there are substantive economies of scope in market access costs. Market access costs differ across destinations, falling more rapidly in scope at nearby regions and at destinations with fewer nontariff barriers. We evaluate a counterfactual scenario that harmonizes market access costs across destinations and find global welfare gains similar to eliminating all current tariffs.

期刊介绍： American Economic Journal: Macroeconomics focuses on studies of aggregate fluctuations and growth, and the role of policy in that context. Such studies often borrow from and interact with research in other fields, such as monetary theory, industrial organization, finance, labor economics, political economy, public finance, international economics, and development economics. To the extent that they make a contribution to macroeconomics, papers in these fields are also welcome.
