Unhealthy food, regulations, and consumer welfare: The US microwaveable popcorn market
利用尼尔森家庭扫描数据估计微波爆米花市场的供需模型，比较禁令和从价税对反式脂肪摄入和消费者福利的影响，发现10%的税能大幅减少反式脂肪且福利损失较小。
Abstract Due to significant health concerns, governments across the world have taken measures to regulate dietary trans fat, for example, through bans and ad‐valorem taxes. We assess the effectiveness of these two strategies and measure their ensuing welfare implications. We estimate a structural demand and supply model for the microwavable popcorn market using NielsenIQ Homescan data. Applying the recovered consumer preferences and marginal costs, we find a ban and a 35% tax result in similar levels of welfare loss and trans fat reduction. A 10% tax can still significantly reduce trans fat consumption (around 48%), while the associated consumer welfare loss is substantially smaller.
