 2007 Johns Hopkins Bloomberg School of Public Health 2 Overview Why tax tobacco? Types of tobacco taxes Impact of tobacco taxes on tobacco product prices Effects of taxes and prices on cigarette smoking and other tobacco use Impact of tobacco taxes on tobacco tax revenues Conclusions

 2007 Johns Hopkins Bloomberg School of Public Health 3 Why Tax Tobacco? Revenue Generation Efficient revenue generation  Primary motive historically and still true in many countries today  Very efficient source of revenue, given:  Low share of tax in price in most countries  Relatively inelastic demand for tobacco products  Few producers and few close substitutes

 2007 Johns Hopkins Bloomberg School of Public Health 4 Why Tax Tobacco? Revenue Generation “Sugar, rum, and tobacco are commodities which are no where necessaries of life, which are become objects of almost universal consumption, and which are therefore extremely proper subjects of taxation.” — Adam Smith, Wealth of Nations, 1776

 2007 Johns Hopkins Bloomberg School of Public Health 5 Why Tax Tobacco? Promote Public Health Promote public health  Increasingly important motive for higher tobacco taxes in many high-income countries  Emerging as important factor in some low- and middle- income countries  Based on substantial and growing evidence on the effects of tobacco taxes and the prices on tobacco use  Particularly among young, less-educated, and low-income populations

 2007 Johns Hopkins Bloomberg School of Public Health 6 Why Tax Tobacco? Promote Public Health “The Parties recognize that price and tax measures are an effective and important means of reducing tobacco consumption by various segments of the population, in particular young persons.” — Framework Convention on Tobacco Control, Article 6

 2007 Johns Hopkins Bloomberg School of Public Health 7 Why Tax Tobacco? External Costs Cover the external costs of tobacco  Less frequently used motive  Account for costs resulting from tobacco use imposed on nonusers  Can also include “internalities” that result from addiction and time-inconsistent preferences

 2007 Johns Hopkins Bloomberg School of Public Health 8 Source: Philip Morris. (1985). Smoking and Health Initiatives. Industry Perspective Industry understands the importance of tobacco taxes  "With regard to taxation, it is clear that in the U.S., and in most countries in which we operate, tax is becoming a major threat to our existence”  "Of all the concerns, there is one—taxation—that alarms us the most. While marketing restrictions and public and passive smoking (restrictions) do depress volume, in our experience taxation depresses it much more severely. Our concern for taxation is, therefore, central to our thinking..."

 2007 Johns Hopkins Bloomberg School of Public Health 9 Types of Tobacco Taxes Variety of tobacco taxes  Taxes on the value of the tobacco crop  Customs duties on tobacco leaf imports and/or exports  Customs duties on tobacco product imports and/or exports  Sales taxes  Value-added taxes  Implicit taxes  Tobacco excise taxes

 2007 Johns Hopkins Bloomberg School of Public Health 10 Two Types of Excises Specific taxes: excises based on quantity or weight (e.g., tax per pack of 20 cigarettes) Ad valorem taxes: excises based on value of tobacco products (e.g., a specific percentage of manufacturer’s prices for tobacco products) Some countries use a mix of specific and ad valorem tobacco excises Many countries apply different types of taxes and/or tax rates on different types of tobacco products  For example: manufactured cigarettes vs. bidis

 2007 Johns Hopkins Bloomberg School of Public Health 11 Specific vs. Ad Valorem Tobacco Excises Strengths/weaknesses depend on a variety of factors and goals of tax Specific taxes  Generally produce a more stable stream of revenue  Real value falls with inflation  Promote higher “quality” products

 2007 Johns Hopkins Bloomberg School of Public Health 12 Specific vs. Ad Valorem Tobacco Excises Ad valorem taxes  More unstable revenues given that revenues depend on industry pricing  Government effectively subsidizes industry price cuts  Rises with inflation If reducing tobacco use is a primary goal, a specific tax is generally preferred  Particularly when regularly adjusted for inflation

 2007 Johns Hopkins Bloomberg School of Public Health 13 Taxes and Tobacco Product Prices Impact of tobacco taxes on tobacco use and other outcomes depends on the impact of tax on prices of tobacco products  Impact on prices will vary based on several factors, including the following:  Structure of tobacco product market  Cost of tobacco product production  Industry price-related marketing efforts  Potential for individual tax avoidance and larger-scale, more organized tobacco product smuggling  Most evidence (largely from the United States) indicates that tobacco tax increases result in comparable tobacco product price increases  That is, tax increases are fully passed on to tobacco users

 2007 Johns Hopkins Bloomberg School of Public Health 17 Increases in Tobacco Product Taxes and Prices Induce current users to try to quit  Many will be successful in long-term Keep former users from restarting Prevent potential users from starting  Particularly effective in preventing transition from experimentation to regular use

 2007 Johns Hopkins Bloomberg School of Public Health 18 Increases in Tobacco Product Taxes and Prices Reduce consumption among those who continue to use Lead to other changes in tobacco-use behavior, including:  Substitution to cheaper products or brands  Changes in buying behavior  Compensation

 2007 Johns Hopkins Bloomberg School of Public Health 19 Price and Tobacco Use in High-Income Countries Well over 100 studies from high-income countries consistently find that:  A 10% increase in price reduces overall consumption of tobacco products by 2.5–5%  Consensus estimate: 10% price increase reduces consumption by 4%  Estimated impact on sales higher in presence of significant tax avoidance and smuggling  Long-run impact larger as addicted users respond over time to permanent increases in taxes and prices

 2007 Johns Hopkins Bloomberg School of Public Health 29 Price Sensitivity and Age Growing evidence that tobacco use among younger persons is two to three times more responsive to price than tobacco use among older persons  Largely based on studies from the United States, but there is growing evidence from other countries  Consistent with economic theory, given:  Lower incomes of youth  Greater importance of peer influences on youth  Influence of addiction  Greater preference for the present among youth

 2007 Johns Hopkins Bloomberg School of Public Health 30 Price Sensitivity and Age Growing evidence that tobacco use among younger persons is two to three times more responsive to price than tobacco use among older persons  Changes in youth prevalence largely result from reductions in initiation of tobacco use  Evidence suggests that higher taxes and prices are most effective in preventing youth from moving beyond experimentation and into regular tobacco use and addiction

 2007 Johns Hopkins Bloomberg School of Public Health 32 Price Sensitivity and Income/Education A growing number of studies find that tobacco use among less- educated and/or lower-income persons is more responsive to price  Economic theory implies that lower-income persons are generally more responsive to changes in prices for goods or services they consume than are higher-income persons  U.K.: lowest socioeconomic group is very responsive to price, while highest socioeconomic group virtually unresponsive to price* * Source: Townsend, J. (1994).

 2007 Johns Hopkins Bloomberg School of Public Health 33 Price Sensitivity and Income/Education A growing number of studies find that tobacco use among less- educated and/or lower-income persons is more responsive to price  U.S.: smoking in households below median income level are about four times more sensitive to price than smoking in households above median*  Similar evidence emerging from low- and middle-income countries * Source: Farrelly, M. (2001).

 2007 Johns Hopkins Bloomberg School of Public Health 34 Dedicated Tobacco Taxes A growing number of governments are using dedicated tobacco taxes (also called hypothecated or earmarked tobacco taxes) to support tobacco control activities  Include “health promotion foundations” and “comprehensive tobacco control programs” Research evidence, largely from high-income countries, shows that funding for tobacco control programs:  Reduces overall tobacco consumption  Increases adult cessation and prevents youth initiation  Reduces tobacco use in other high-risk populations

 2007 Johns Hopkins Bloomberg School of Public Health 35 Tobacco Taxes and Deaths Caused by Tobacco Given the evidence on the impact of tobacco taxes and prices on tobacco use, large increases in taxes globally would significantly reduce premature deaths caused by tobacco use  Short-run reductions in deaths result from increased cessation  Significant health benefits of cessation  Long-run reductions result from preventing initiation

 2007 Johns Hopkins Bloomberg School of Public Health 41 What Is the “Right” Level of Tobacco Taxes? This is a complex question that depends on a variety of factors, including the following:  Motives for tobacco taxation  Improving public health vs. generating revenue? (taxes can accomplish both)  Tax rates in neighboring countries  Potential for tax avoidance and smuggling World Bank suggests that a useful yardstick is two-thirds to four- fifths of the price accounted for by tax in countries that have taken a comprehensive approach to reducing tobacco use

 2007 Johns Hopkins Bloomberg School of Public Health 42 Summary Higher tobacco taxes will lead to higher tobacco product prices Increases in tobacco taxes and prices will reduce tobacco use and the disease and death it causes  Increase cessation among current users  Prevent relapse among former users  Prevent initiation of regular tobacco use  Reduce consumption among those who continue to use Higher tobacco taxes raise revenues  New revenues can be used to support comprehensive tobacco- control efforts that would further reduce tobacco use
