Product Entry Effects of Singapore’s High-Sugar Beverage Advertising Restrictions

Abstract

This paper examines how firms adjust product design and innovation in response to a comprehensive regulatory intervention targeting high-sugar beverages in Singapore. In 2019, Singapore announced a nationwide policy combining mandatory front-of-package nutrition labeling with a ban on advertising for sugar-sweetened beverages (SSBs) exceeding a specified sugar threshold. While prior research has largely focused on demand-side responses to soda taxes and labeling policies, less is known about how firms alter product portfolios in response to advertising restrictions.

The central research question is: how do advertising bans and labeling requirements affect firms’ product launch strategies and sugar content decisions? To address this, we use detailed product-level data covering SSB markets from 2016 to 2023. The empirical strategy combines synthetic control methods with a difference-in-differences framework to identify causal effects of the policy announcement on newly introduced products across major beverage categories.

The results show substantial supply-side adjustments following the policy. The average sugar content of newly launched products declines significantly in four of six major categories: by 38 percent in instant coffee, 24 percent in soft drinks, 21 percent in iced coffee, and 18 percent in juice. These reductions are not concentrated near the regulatory threshold, but instead reflect a broad shift toward low- and zero-sugar product introductions. This pattern is consistent with firms responding to advertising restrictions rather than narrowly reformulating products to avoid labeling penalties.

We also find that the response is widespread across both domestic and multinational firms, though the magnitude varies by category and market presence. In addition, evidence suggests that reformulation extends beyond new product launches to existing branded products, indicating a broader strategic adjustment rather than isolated niche responses.

These findings highlight an important supply-side channel through which public health policies operate. By restricting advertising, the policy alters firms’ incentives to market high-sugar products, encouraging structural changes in product composition. The results suggest that advertising bans can serve as a powerful complement to sugar taxes and labeling policies in reducing population-level sugar exposure. More broadly, this study contributes to policy discussions by demonstrating how regulatory design influences firm behavior, product innovation, and long-run health outcomes.
