Taxing mechanisms on salty foods: investigation of effectiveness through price elasticity and cross price elasticity of demand.

ABSTRACT:

Background

Salt consumption control strategies can help to decrease hypertension and related cardiovascular diseases. Taxation mechanisms help to reduce the utilization of harmful commodities like salts. This study aims to analyze the impact of taxing salty foods on salt intake in Iran by examining the price elasticity of demand (PED) and cross-price elasticity of demand (XED) for salty foods.

Methods

This study used 38,328 household-level data from the 2019 Iranian Household Income and Expenditures Survey. This PED and XED for salty foods were calculated, and changes in household salt consumption due to salt taxation were estimated using a mathematical simulation method.

Results

The findings revealed that the PEDs for noodles and pilaffs (- 4.89) and bread (- 2.03) a
