报告摘要：

Food adulteration poses a serious threat topublic health. This paper develops a modeling framework to examine whethersupply chain traceability and government inspection can effectively deteradulteration. We study the adulteration behavior of farmers in two competingsupply chains, one is traceable and the other is not, each consisting of onefarm and one retailer. The farmers in each supply chain have incentive toengage in adulteration to increase the perceived quality of the output. Thegovernment, who conducts sampling tests on products sold by the retailers, willimpose a penalty if adulteration is caught. For the traceable supply chain, theadulteration farm can be precisely targeted and will be penalized; while forthe untraceable supply chain, the penalty can only be imposed on the retailer.We fully characterize the equilibrium adulteration behavior for farms in bothtypes of supply chains and analyze how traceability cost, initial qualitydifference and government penalty jointly impact the equilibrium adulterationbehavior. Our results show that supply chain traceability may inadvertentlyinduce the farmer to adulterate when the traceable supply chain has acompetitive advantage over the untraceable one. Under this circumstance, thetraceable farmer adulterates to intensify the competitive advantage, and getextra profit even the government penalty will be posed on him directly. Theresults highlight the limitation of relying on traceability and retailer-endinspection to deter adulteration in a competitive environment. Our empiricalanalysis with sample testing data on Chinese agricultural market further validatesthe results of our theoretical model.
