Tainted food, low-quality products and trade

This paper examines international trade in tainted food and other low-quality products. Wefirst find that for a large class of environments, free trade is the trading system that conveysthe highest incentives to produce non-tainted high-quality goods by foreign exporters.However, free trade cannot prevent the export of tainted products, and the condition fortainting to arise becomes more easily satisfied, if the marginal cost of high-quality productionincreases or if errors of testing product quality matter. We also examine cases of imagebuildinginvestments and sabotage of rivals, and find that a tariff in either case reduces theforeign firm’s incentives to produce high quality, which in turn tends to increase importtainting.
