Efficacy of the tobacco tax policy in the presence of product heterogeneity: A pseudo-panel approach applied to Spain

Impact of tobacco price and taxation on affordability and consumption of tobacco products in the South-East Asia Region: A systematic review

INTRODUCTION

The objective of the review was to study the impact of tobacco taxes or prices on affordability and/or consumption of tobacco products in WHO South-East Asia Region (SEAR) countries, overall and by socioeconomic status; and change in consumption of one tobacco product for a given change in price/tax on another tobacco product.

METHODS

The searches were made in five databases (Medline, Embase, Cinahl, EconLit, Tobacconomics) using keywords such as 'tobacco', 'tax', 'price', 'impact' with their synonyms. Additionally, the first 100 articles through google search and e-reports from targeted sources were also reviewed. Studies illustrating the impact of prices/taxes on consumption/affordability of tobacco products in SEAR, in English and with no limitation on year, were included in the review. After two steps of screening, data from 28 studies were extracted using a structured and pre-tested data extraction form.

RESULTS

Of the 28 studies, 12 studies reported an inverse association between price and consumption/affordability, while 11 studies reported no or positive association between price and consumption/affordability of tobacco products. Five studies had unclear interpretations. The majority of studies estimated that the less affluent group were more price responsive compared to the more affluent group. Some studies indicated increased consumption of one product in response to price rise of another product, although, the findings were inconsistent.

CONCLUSIONS

The findings of our review support the use of tobacco tax and price measures as effective tools to address the tobacco epidemic. Our findings, however, also emphasize the importance of increasing tobacco product taxes and prices sufficiently to outweigh the effects of income growth, in order for the measures to be effective in reducing the affordability and consumption of tobacco products.

Using Compensating Variation to Measure the Costs of Taxing Cigarette in Iran

Background: The impact of pricing strategies on different socioeconomic groups is not uniform. There is urgency in addressing of characteristics of household demand to make a policy choice in line with development goals. Objectives: This study was done to assess the effect of welfare loss from counterfactual tax-induced cigarette price increases on representative smokers by different expenditure quintiles in Iran. Methods: This analytical study was conducted using pooling cross-sections and compensating variation (CV) to evaluate the costs of taxing cigarettes. The data source used in our study was the Household Income and Expenditure survey (HIES) from 2001 - 2017. We did an almost ideal demand system (AIDS) analysis to estimate elasticities for cigarette demand and compute welfare losses from simulated cigarette price increases by socioeconomic groups. We used STATA version 15.1 (StataCorp, College Station, TX, USA), and Microsoft Excel 2016 to undertake the relevant analyses and estimates. Results: The highest loss was suffered by households of the poorest quintile, who should afford 1.41%, 2.47 %, and 3.20% more budget in the long-run, respectively, as the result of three simulated price increases to stay at the same well-being as before. Conclusions: Concerning direct welfare loss from the cigarette taxation reform in Iran, and focusing on low-income groups, such a policy can be considered as regressive. However, this regressivity can be reduced by informing strategies to redirect sin tax revenues that benefit the poor.
