Food Policy and Household Food Waste
研究了旨在提高家庭食物利用率和调整市场价格的食品政策如何影响均衡状态下的家庭食物浪费，发现降低边际利用成本和提高生鲜食品价格的政策会加剧浪费，而提高加工食品价格的政策则可能减少浪费。
Abstract Reducing household food waste is an important policy objective. In this paper we examine how equilibrium food waste among households is influenced by food policies designed to increase household food utilization and to alter household food purchasing behavior by adjusting market prices. We demonstrate that policies that reduce the marginal cost of household food utilization and that raise fresh food prices result in greater food waste for households with sufficiently price‐elastic demand for fresh food. Policies that raise the processed food prices increase fresh food consumption, but nevertheless reduce food waste, provided that fresh and processed foods are substitutes in utility and the equilibrium food utilization rate in a household is sufficiently high.
