英文文献：An Economic Analysis of Fresh Fruit and Vegetable Consumption: Implications for Overweight and Obesity among Higher- and Lower-Income Consumers
英文文献作者：Jones, Eugene
英文文献摘要：
This paper examines the purchasing behavior of higher- and lower-income consumers for fresh fruit and vegetables. Lower-income consumers are shown to have higher own-price elasticities for most sub-categories of produce and to pay lower per unit prices for all but two sub-categories. Results suggest that lower-income consumers are purchasing lower-quality commodities and their incomes constrain their ability to increase consumption to reach a more healthy and nutritious diet.
