This paper uses supermarket scanner data to estimate brand- and packaging-specific own- and cross-price elasticities for beer. We find that brand- and packaging-specific beer sales are highly price elastic. Cross-price elasticity estimates suggest that individuals are more likely to buy a higher-volume package of the same brand of beer than they are to switch brands. Policy simulations suggest that regulation of volume-based price discounts is potentially more effective than a tax increase at reducing beer consumption. Our results suggest that volume-based price discounting induces people to buy larger-volume packages of beer and may lead to an increased overall beer consumption.
本文利用超市扫描数据来估计啤酒品牌和包装特定的自价格弹性和交叉价格弹性。我们发现，品牌和包装特定的啤酒销售具有很高的价格弹性。交叉价格弹性估计表明，个人更有可能购买同一品牌啤酒的大容量包装，而不是更换品牌。政策模拟表明，基于容量的价格折扣监管在减少啤酒消费方面可能比提高税收更有效。我们的结果表明，基于容量的价格折扣会诱使人们购买大容量包装的啤酒，并可能导致啤酒总消费量增加。
