本文首先观察到，企业的出口比率（出口销售比率）在不同企业之间差异很大，而且大型出口商的出口比率通常较高。我们将出口比率的差异与企业层面的运输成本差异联系起来。根据这些数据，我们假设运费率是企业出口量的函数。我们使用日本制造业企业层面的数据来测试我们的模型。我们首先估计的弹性，运费率相对于公司层面的出口量在部门层面。当将这些估计值反馈到模型中时，它可以解释企业层面出口率50%以上的变化。
This paper starts out from the observation that the export ratios of firms (export to sales ratios) vary greatly among firms and that they are systematically higher for larger exporters. We relate the difference in export ratios to firm-level differences in transport costs. In accordance with the data, we assume that freight rates are a function of firm-level export volumes. We test our model using Japanese manufacturing firm-level data. We first estimate the elasticity of the freight rate with respect to firm-level export volumes at the sector level. When feeding these estimates back into the model, it can explain more than 50% of the variation in firm-level export ratios.
