Data for: Exchange rate pass-through and product heterogeneity: Does quality matter on the import side?

Abstract of associated article: This paper investigates theoretically and empirically the heterogeneous response of exporters to real exchange rate fluctuations due to the quality of imported inputs and exported output. We develop a model where the production of high-quality products requires high-quality inputs sold in monopolistically competitive foreign markets. The model predicts that exporters using imported inputs have low exchange rate pass-through, but this effect is weaker for firms shipping high-quality goods. This is due to the heterogeneous price adjustments of foreign suppliers selling inputs of different quality. We test the predictions of the model using Italian firm-level trade data for the period 2000–2006. The empirical analysis shows that the imports of intermediates have a significantly weaker effect in reducing the exchange rate pass-through into the export price of high-quality varieties. By showing that the import price of high-quality inputs is less sensitive to exchange rate variations, we provide evidence supporting the theoretical hypothesis that the pricing power of input suppliers weakens the import channel.关联论文摘要：本文从理论与实证两个层面，探究了出口企业因进口中间品与出口产品质量差异，针对实际汇率波动的异质性响应。本文构建了一个理论模型，其中高质量产品的生产需使用在垄断竞争海外市场中售卖的高品质投入品。该模型预测，使用进口中间品的出口企业汇率传递（exchange rate pass-through）效应较低，但对于出口高品质产品的企业而言，这一效应会有所减弱。这一现象源于销售不同质量投入品的海外供应商，其价格调整行为存在异质性。本文使用2000年至2006年的意大利企业层面贸易数据，对模型的理论预测进行了实证检验。实证分析显示，进口中间品在降低高品质品类出口价格的汇率传递效应方面，其作用显著更弱。本文通过证实高品质进口投入品的进口价格对汇率变动的敏感性更低，为“投入品供应商的定价权会削弱进口渠道的影响”这一理论假说提供了经验证据。
