Price Elasticities of Food Demand: Compensated vs Uncompensated
提出一种方法，从食物消费的价格弹性中剔除收入效应，得到补偿性弹性，并发现不同收入群体的补偿性弹性存在差异，对政策评估有参考价值。
Two recent studies have provided a comprehensive review/summary of a large number of estimates of the price elasticity of food consumption using a meta-regression approach. In this letter, we introduce a way of removing the income effect from these elasticities to recover the compensated elasticities. Although the income effect is small, the compensated elasticities vary by income group. Both types of elasticity should possibly be considered when assessing the impact of policy changes on food consumption. Copyright © 2015 John Wiley & Sons, Ltd.
