How Bottle Deposit Return Schemes Affect Retail Prices and Lead Consumers to Larger Package Sizes
Guyt and Keller aimed to understand how bottle deposit return schemes influence retail prices and consumer purchasing habits. With the EU mandating deposit return systems by 2029, the researchers were curious about the broader effects of these environmental policies.
The study revealed that retailers increased the prices of deposit-covered bottles by an average of 4%, with smaller bottles seeing price hikes up to 13%. Consequently, sales of these smaller bottles dropped by 6%, while sales of larger bottles (1 liter) rose by 10%. Retailers facing higher operational costs for processing returns were more likely to raise prices. Additionally, consumers skeptical of government regulations tended to avoid deposit-covered bottles, opting for larger formats instead.
Bottle deposit schemes do more than boost recycling; they reshape consumer buying habits and retailer pricing strategies. While these schemes help reduce plastic waste, they also lead to unintended effects, such as increased prices and shifts towards larger package sizes. For policymakers and marketers, this study highlights the importance of considering convenience, costs, and consumer values when implementing regulatory changes.
