摘要

本文考察了贸易政策不确定性（TPU）对整个收入分配中消费者价格的异质性影响。使用特定收入的CPI数据和从月度关税费率得出的TPU冲击测量，我通过当地预测来估计脉冲响应。结果表明，与低收入家庭相比，高收入家庭面临的价格在TPU冲击下上涨更为强烈。这些发现表明，不确定性导致的需求效应在低收入家庭中更为明显，这突出了在评估TPU的宏观经济影响时考虑异质性的重要性。

Heterogeneous price responses to trade policy uncertainty: Evidence from income-specific CPIs

This paper examines the heterogeneous effects of trade policy uncertainty (TPU) on consumer prices across the income distribution. Using income-specific CPI data and a TPU shock measure derived from monthly tariff rates, I estimate impulse responses via local projections. The results show that prices faced by top-income households rise more strongly in response to TPU shocks than those faced by low-income households. These findings suggest that uncertainty-induced demand effect is more pronounced among low-income households, highlighting the importance of accounting for heterogeneity when assessing the macroeconomic implications of TPU.

期刊介绍： Many economists today are concerned by the proliferation of journals and the concomitant labyrinth of research to be conquered in order to reach the specific information they require. To combat this tendency, Economics Letters has been conceived and designed outside the realm of the traditional economics journal. As a Letters Journal, it consists of concise communications (letters) that provide a means of rapid and efficient dissemination of new results, models and methods in all fields of economic research.
