Market Intervention Policies for Increasing the Consumption of Nutrients by Low Income Households
用市场均衡模型比较食品补贴、收入转移和农业投入补贴对低收入人群营养素摄入的影响，发现对特定谷物的消费者补贴成本最低，但黑市可能使其成本与收入补贴相当。
Abstract This study employs a market equilibrium displacement approach to examine the nutrient consumption effects of market intervention programs such as food subsidies, income transfers, and agricultural input subsidies. The results permit comparison of the direct treasury costs of achieving marginal increases in nutrient intake with alternative programs. When applied to a case study of the food markets and population of Cali, Colombia, it was found that a marginal increase in caloric intake among the poor could be achieved at lowest cost with a consumer subsidy of certain cereals, although black market activity might raise this cost to that of an income subsidy.
