Retail price discrimination and food waste
研究了零售商如何通过最低质量标准实施基于质量的价格歧视策略，并利用美国大型零售商数据发现，这种策略导致约7.5%的零售食物浪费。
Abstract We examine a food retailer’s incentive to use a minimum quality standard as part of a quality-based price-discrimination strategy and show how price discrimination can result in a substantial level of retail food waste. Using data from a major US food retailer, we estimate a structural model of retail price discrimination and conduct a series of counter-factual experiments to demonstrate that observed retail prices are consistent with quality-based price discrimination in the retail market. Our findings indicate that quality standards on fresh produce can explain a substantial proportion ($7.5\%$) of food waste by retailers in the US.
