Taxation of tobacco, alcohol, and sugar-sweetened beverages: reviewing the evidence and dispelling the myths.

The article reviews the large body of evidence on how taxation affects the consumption of tobacco, alcohol, and sugar-sweetened beverages (SSB). There is abundant evidence that demand for tobacco, alcohol, and SSB is price-responsive and that tax changes are quickly passed on to consumers. This suggests that taxes can be highly effective in changing consumption and reducing the burden of diseases associated with consuming these products. Tobacco, alcohol, and SSB industries oppose taxation on similar grounds, mostly on the regressivity of taxes since regressive taxes take a larger percentage of income from low income earners than from middle and high income earners; but also on the effects taxes might have on employment and economic activity; and, in the case of tobacco, the effects taxation has on illicit trade.Contrary to industry arguments, evidence shows that taxation may have short-term negative financial consequences for low-income households. However, medium and long-term financial benefits from reduced healthcare costs, better health, and welfare largely compensate for such consequences. Moreover, taxation does not negatively affect aggregate economic activity or employment, as consumers switch demand to other products that generate employment and may compensate for any employment loss in taxed sectors. Evidence also shows the revenues generated are generally spent on labour-intensive services. In the case of illicit trade in tobacco, evidence shows that illicit trade has not increased globally (rather the opposite) despite increases in tobacco taxes. Profit-maximising smugglers increase illicit cigarette prices along with the increases in licit cigarette prices. This implies that even when increased taxes divert some demand to the illicit market, they push prices up in the illicit market, discouraging consumption.

Prices, alcohol use initiation and heavy episodic drinking among Chilean youth.

AIMS: To examine the association between alcohol prices and age of initiation of alcohol use and the association between age of alcohol use initiation and heavy episodic drinking (HED) among adolescents in Chile. DESIGN: We estimated discrete-time hazard models using retrospective data and generalized ordered probit models with repeated cross-sectional data. SETTING: Chile. PARTICIPANTS: A total of 248 336 urban youth who attended secondary school between 2003 and 2015 and self-reported ever having tried alcohol. MEASUREMENTS: We created drinking histories from self-reported responses of age, age of alcohol use initiation and year/month of survey. From two self-reported responses, we created a four-category ordinal variable of heavy episodic drinking: none, one to two, three to nine and more than 10 HED episodes in the past 30 days. We constructed a monthly measure of real alcohol prices using the all-items and alcohol component of the Consumer Price Index compiled by Chile's statistical agency, the Instituto Nacional de Estadísticas. FINDINGS: First, we found negative, statistically significant and policy-meaningful associations between alcohol prices and the age of alcohol use initiation. The estimated price elasticity of delay was -0.99 [95% confidence interval (CI) = -1.30, -0.69]. A 10% increase in real alcohol prices was associated with delayed alcohol use initiation of approximately 6.6 months. Secondly, we found that youth who had started drinking alcohol at a later age had statistically significant and substantially lower probabilities of having reported HED during the previous month. For example, youth who started drinking at 16 were 4.9 (95% CI = 4.2-5.6) percentage points more likely to have reported no HED in the previous month relative to youth who started drinking alcohol when aged 12 years or younger. CONCLUSIONS: Increasing the price of alcohol products may delay alcohol initiation among young people in Chile. Chilean youth who start drinking alcohol later may engage in less harmful drinking practices.

Association of Tobacco Control Policies With Youth Smoking Onset in Chile.

IMPORTANCE: Tobacco smoking is still responsible for more than 6 million preventable deaths annually, most of which occur in low- and middle-income countries. South American countries, Chile in particular, endure some of the highest cigarette smoking prevalence rates globally. Despite the lack of any meaningful increases in cigarette taxes (the most effective tobacco control measure) between 1999 and 2014, cigarette prices in Chile increased sharply almost entirely driven by British American Tobacco (BAT). OBJECTIVE: To examine the associations between cigarette prices and nonprice tobacco control policies targeted at youth introduced in 2006 (Law 20105) and smoking onset among Chilean youths. DESIGN, SETTING, AND PARTICIPANTS: This study used data from 8 waves of a large national school survey of urban communities in Chile conducted between October and December in 2001, 2003, 2015, 2007, 2009, 2011, 2013, and 2015 and discrete-time hazard models. Data analysis was performed from May 2017 to January 2019. EXPOSURES: Prices, advertising, and retail restrictions. MAIN OUTCOMES AND MEASURES: Smoking onset (the transition between never smoking and smoking) in youth. RESULTS: In this study of 181 624 survey respondents in 8751 Chilean secondary schools, higher prices (own-price elasticity [percentage change in quantity demanded in response to a 1% change in price], -0.40; 95% CI, -0.45 to -0.36) and the tobacco control policies enacted in 2006 (hazard ratio, 0.83; 95% CI, 0.81-0.85) were associated with lower hazards of starting smoking. The study found that an increase in real prices of 58.6% and the introduction of Law 20105 were associated with similar lower hazards of starting smoking (hazard ratio, 0.83; 95% CI, 0.81-0.85); in comparison, between 1999 and 2017, inflation-adjusted cigarette prices increased by 206%. CONCLUSIONS AND RELEVANCE: The findings suggest that higher prices initiated by BAT and the tobacco control policies enacted by the Ministry of Health in 2006 were associated with lower hazards of starting smoking in Chilean youth. Large cigarette tax increases may be a strategy that can be used to help reduce smoking among youths in Chile.

[The Impact of Prices and Taxes on the Use of Tobacco Products in Latin America and the Caribbean]. / El impacto de los precios e impuestos sobre el consumo de productos de tabaco en América Latina y el Caribe.

We examined the impact of tobacco prices or taxes on tobacco use in Latin America and Caribbean countries. We searched MEDLINE, EconLit, LILACS, unpublished literature, 6 specialty journals, and reviewed references. We calculated pooled price elasticities using random-effects models. The 32 studies we examined found that cigarette prices have a negative and statistically significant effect on cigarette consumption. A change in price is associated with a less than proportional change in the quantity of cigarettes demanded. In most Latin American countries, own-price elasticity for cigarettes is likely below -0.5 (pooled elasticities, shortrun: -0.31; 95% confidence interval = -0.39, -0.24; longrun: -0.43; 95% CI = -0.51, -0.35). Tax increases effectively reduce cigarette use. Lack of studies using household- or individual-level data limits research's policy relevance.

Examinamos la repercusión de los precios del tabaco o los impuestos sobre el consumo de tabaco en países de América Latina y el Caribe. Efectuamos búsquedas en MEDLINE, EconLit, LILACS, bibliografía inédita, seis revistas especializadas y referencias de revisiones. Calculamos las elasticidades combinadas de los precios usando modelos de efectos aleatorios. En los 32 estudios que examinamos se observó que los precios de los cigarrillos tienen un efecto negativo y estadísticamente significativo sobre el consumo. Un cambio en el precio está asociado con un cambio menos que proporcional en la magnitud de la cantidad demandada de cigarrillos. En la mayoría de los países latinoamericanos, la elasticidad-precio para los cigarrillos probablemente sea inferior a –0,5 (elasticidades combinadas, a corto plazo: –0,31; intervalo de confianza de 95% = –0,39 a –0,24; a largo plazo: –0,43; IC de 95% = –0,51 a –0,35). Los aumentos de impuestos reducen eficazmente el consumo de cigarrillos. La falta de estudios que usen datos de hogares o de individuos limita la pertinencia de las políticas de investigación.
