本文探讨了毒品价格中的数量折扣和质量（纯度）溢价。它研究了药品价格如何取决于交易规模的几个模型。国内销售网络树形模型所暗示的一种简单关系与西方国家信息网提供的1984-1991年各种非法药物的数据十分吻合。质量溢价解释得不太清楚。据观察，价格不仅仅是纯数量的函数;顾客在给定纯度下为2克支付的价格比在两倍于该纯度的情况下为1克支付的价格高。尽管如此，白色海洛因、棕色海洛因和可卡因粉末的纯度仍有一定的溢价，而甲基苯丙胺、快克或海洛因焦油的纯度则没有溢价。估计的系数反映了已知的现象，如可卡因和黑焦油海洛因价格暴跌;直观上合理但没有记录的现象，如墨西哥边境附近棕色海洛因的折扣;以及一些意想不到的结果，如sinsemilla和其他大麻产品的销售之间的明显差异。
This article explores quantity discounts and quality (purity) premia in the prices of illicit drugs. It examines several models of how drug prices might depend on transaction size. A simple relation implied by a tree model of the domestic distribution network fits data provided by the Western States Information Network for 1984-1991 quite well for various illicit drugs. Quality premia are less well explained. It is observed that price is not a function of pure quantity alone; customers pay more for 2 grams at a given purity than they do for 1 gram at double that purity. Nevertheless, some purity premia are observed for white heroin, brown heroin, and powder cocaine, although not for methamphetamines, crack, or heroin tar. The estimated coefficients reflect known phenomena such as the collapses in the prices of cocaine and black tar heroin; intuitively reasonable but undocumented phenomena, such as discounts for brown heroin near the Mexican border; and some unexpected results, such as an apparent difference between the distribution of sinsemilla and that of other cannabis products.
