各国的粮食采购情况大不相同。我们使用来自美国、法国和英国的详细的家庭层面数据来（i）记录这些差异;（ii）估计食物和营养素的需求系统;（iii）如果家庭面临来自其他国家的价格和营养特征，则模拟反事实选择。我们发现，价格和特性的差异是重要的，可以解释一些差异（如。例如，在一个实施例中，美国和法国在热量摄入方面的差异），但通常不能解释许多成分模式本身。相反，似乎需要经济环境和偏好差异之间的相互作用来解释跨国差异。
Food purchases differ substantially across countries. We use detailed household-level data from the United States, France, and the United Kingdom to (i) document these differences; (ii) estimate a demand system for food and nutrients; and (iii) simulate counterfactual choices if households faced prices and nutritional characteristics from other countries. We find that differences in prices and characteristics are important and can explain some difference (e. g., United States-France difference in caloric intake) but generally cannot explain many of the compositional patterns by themselves. Instead, it seems an interaction between the economic environment and differences in preferences is needed to explain cross-country differences.
