Abstract: We examine the impact of tariff reductions on cost-of-living inequality in a low-income country: Cambodia. We use a novel dataset on household consumption that distinguishes between imported, domestic, and home-produced goods within finely disaggregated product categories. We find that wealthier households have substantially higher expenditure share on imported final goods. Consequently, these households experience greater reductions in the cost of living from tariff cuts. This pro-rich effect is further amplified by the disproportionate reliance of wealthier households on the domestic goods that use imported inputs more intensively. We argue that the positive correlation between income and import expenditure shares is likely a common feature of low-income countries, and ignoring this heterogeneity may lead to a substantial underestimation of the pro-rich effects of trade liberalization in such economies.
