Consequences of Bottle Bills: How Bottle Deposit Return Schemes Affect Retail Prices and Lead Consumers to Larger Package Sizes

Abstract:

Plastic waste has doubled in the past two decades, and less than 10% of plastic waste is recycled. “Bottle bills” are legislation to combat plastic waste by increasing recycling rates, by adding a per-bottle deposit that gets refunded to consumers who return empty containers. Industry experts are divided over the retail sales and price implications of such measures. To clarify the implications of such legislation, the current study uses a synthetic difference-in-differences approach to investigate how New York’s 2009 law, targeting pure bottled water in containers < 128 fl. oz., affected consumers and retailers in terms of whether (1) prices of bottled beverages changed, (2) the bottle bill affected sales of bottled beverages, and (3) to what extent do the answers depend on the package size. The results reveal that retailers increased prices of items covered by the bottle bill by 5% while keeping prices of other items, outside the bottle bill’s scope, constant. Volume sales in the water category decreased by 2.3%. This study finds substantial differences in these effects across package sizes and establishes three key drivers of the price and sales changes following a bottle bill introduction.
