分析了1975年加州农药导致蜜蜂死亡对养蜂人和杏仁种植者的经济损失,并计算了蜂群的边际收益产品,发现设立蜜蜂保护区能带来净收益。

Abstract

Abstract Pesticide‐induced beekills cost California beekeepers almost $@@‐@@1 million in 1975. California almond growers depend on bees for crop pollination and thus lost approximately $@@‐@@200,000 from beekills during this same year. A partial equilibrium framework is employed to calculate the marginal revenue product of a bee colony to the beekeeper and the marginal value product of a bee colony employed by an almond grower. The issue of bee protection is addressed in the context of the Tulare County citrus nectary. It is found that substantial net gains in total income were realized from the establishment ofa bee protection area.
