Working Papers

• The Impact of Tariffs on Inflation and Household Budgets Across Income Levels and Regions in the US. (w/ Erick W. Rengifo). Submitted, Under Review. [SSRN_WP].
  Abstract: This paper examines the impact of tariffs on inflation and household budgets across income levels and regions in the United States, focusing on food and beverages—necessity goods that disproportionately burden low- and middle-income households. Using WTO trade data and the U.S. Consumer Expenditure Survey, we identify key trading partners and analyze how tariff-induced food price increases affect household consumption. Our analysis shows that lower-income households spend a significantly larger share of their budget on food and consume far less in absolute terms—only one-third of the quantity consumed by top earners. We conduct a calibration exercise using Cobb-Douglas and Constant Elasticity of Substitution (CES) utility functions to simulate the effects of 5% and 10% price increases. Results show that utility losses for the lowest income quintile are up to 50% higher than those for the highest quintile, even after allowing for substitution. These findings underscore the regressive nature of tariffs on essential goods and highlight the need for targeted policy measures—such as enhanced tax credits or income support—to offset the welfare losses among vulnerable households.
