Résumé
Retail prices of illicit drugs have fallen despite rising supply disruption. This article presents and empirically tests a model which may explain the price puzzle. Supply disruption increases the cost of purity. Illicit drugs are experience goods, with demand depending on the seller’s purity reputation. There is an equilibrium in which seizures decrease purity, reducing future demand and prices. These predictions are tested using monthly data for crack cocaine in Washington DC. Persistence of the series is exploited to handle endogeneity resulting from seizures mirroring supply. A 10% increase in seizures reduces purity by 4.7% and future prices by 2.3%.
