Summary of the Mexican Experience with Taxes on Sugar-Sweetened Beverages and Energy-Dense Foods of Low Nutritional Value

Core Content

This document presents a discussion paper analyzing the Mexican experience with implementing taxes on sugar-sweetened beverages (SSBs) and energy-dense foods of low nutritional value as part of a broader strategy to combat obesity, overweight, and diabetes. The paper outlines the context, design, and impact of these taxes, and proposes a monitoring framework for future evaluation.

Main Objectives

1. To understand the context in which the fiscal policy was enacted, including the reasons behind the Mexican Government's decision to implement these taxes.
2. To describe the main features of the taxes on SSBs and energy-dense foods of low nutritional value.
3. To evaluate the design and implementation process of the policy.
4. To assess the impact of these taxes on fiscal revenue, prices, and consumption among different population groups.
5. To provide options for regular monitoring of the reform using publicly available data.

Key Findings

• Health Burden: Mexico faces a significant health and economic burden due to the high prevalence of obesity and overweight. Over 2/3 of adults are overweight or obese, with at least 1/3 being obese. The country has the second-highest adult obesity rate among OECD nations.
• Non-Communicable Diseases (NCDs): Obesity is a major risk factor for NCDs such as diabetes and cardiovascular diseases, which are the leading causes of healthy life years lost in Mexico.
• Policy Context: The Mexican Government implemented these taxes as part of a comprehensive strategy to prevent and control obesity, overweight, and diabetes. This strategy includes fiscal policy, regulation, health promotion, and improved access to healthcare services.
• Tax Design: The tax on SSBs is a fixed one-peso-per-liter tax, which is equivalent to a 10% price increase on drinks with added sugar. The tax on energy-dense foods is an 8% ad valorem tax on products with 275 kcal or more per 100 grams. Some basic foods, like corn and wheat tortillas, are exempt.
• Impact on Consumption and Prices: The taxes have led to increased prices and reduced consumption, particularly of SSBs. The reduction in consumption was more pronounced among the poorest income groups.
• Monitoring Framework: The study proposes the use of price and volume indicators based on publicly available data to monitor the impact of the tax reform continuously.

Tax Implementation and Outcomes

• Fiscal Revenue: The taxes have successfully increased government revenue and the prices of taxed products.
• Consumption Trends: Post-tax consumption of SSBs decreased by 6% in the first year, while consumption of untaxed beverages, such as bottled water, increased by 4%. The largest impact was observed in the poorest households.
• Substitution Effects: There is some evidence of substitution towards cheaper or lower-priced versions of taxed products, particularly within the same brand or product category.
• Elasticity Analysis: The demand for SSBs is inelastic, but more elastic when focusing on specific products like sodas. The elasticity decreases with higher income levels.
• Comparison with Other Countries: Despite the tax, SSB prices in Mexico remain relatively low compared to countries like Argentina and Brazil, suggesting potential for further price increases.

Challenges and Considerations

• Controversy: The use of fiscal policy for health promotion is still a controversial topic. There are concerns about potential resistance from businesses and consumers.
• Data Limitations: While the study uses household surveys and public data, there are limitations in fully capturing the impact of the taxes on health outcomes.
• Need for Continued Monitoring: The study emphasizes the importance of ongoing monitoring through the development of indicators to assess the effectiveness of the reform.

Conclusion

The Mexican tax on SSBs and energy-dense foods of low nutritional value has had a measurable impact on consumption and prices, with the greatest effect seen in lower-income groups. However, the debate continues regarding its impact on health outcomes. Continued monitoring using available data is essential to assess the long-term effectiveness of the policy and to guide future public health interventions.
