Abstract

This study examines the impact of faith-based consumption on household utility and economic resilience in predominantly Muslim societies, with a particular focus on Iran's economy. This study utilizes a Dynamic Stochastic General Equilibrium (DSGE) model; household consumption is categorized into halal and non-halal segments to assess the relationship between the share of halal goods and overall utility outcomes. The behavioral DSGE model simulates responses to shocks in technology, income, and government spending, examining how religious preferences shape consumption decisions. The findings reveal that faith-based consumption plays a significant role in promoting financial discipline, consumer moderation, and subjective well-being. Religious orientation leads to responsible budget allocation and enhances household welfare through institutional support, poverty alleviation, and sustainable market behavior. Empirical findings indicate that higher shares of halal consumption are positively associated with utility and welfare gains. Furthermore, strong religious commitment enhances household resilience, mitigates macroeconomic vulnerability, and fosters a consistent intertemporal consumption pattern under economic stress. Simulations indicate that higher halal consumption shares enhance household welfare and stabilize consumption under economic stress.
