Intoxicant Consumption Dynamics under Alcohol Prohibition: Evidence from India

This paper examines the effects of an alcohol prohibition law in Bihar, India, on intoxicant consumption. We implement a dynamic difference-in-difference estimation strategy using longitudinal data on monthly household expenses, exploiting state-level variation in policy exposure and household-level variation in alcohol use. We document that alcohol- consuming households in Bihar reduced their spending on tobacco products following the ban announcement, indicating complementarity between alcohol and other intoxicants; however, after its strict enforcement, when alcohol was unavailable, these households gradually increased their tobacco consumption. We find reallocation in healthcare spending: urgent medical expenses decrease with increased spending towards positive lifestyle changes.
