In part to make exports easier for the exporting firm, in part in response to the once unreliable Mexican telephone system, and in part to manage the assorted trade and transportation barriers, a system of intermediaries has developed along the U.S.-Mexican border, commonly referred to as 'brokers.' The scope of their activities can vary widely. Virtually all such firms maintain refrigerated warehouse facilities and handle the transfer from Mexican to U.S. transport equipment. The majority act strictly as brokers, not taking title to the product, while others also are wholesalers, purchasing and reselling the product. It is most common for 'brokers' to accept product at their facilities on the U.S. side and have no involvement, other than telephone communications and occasional visits to assess product availabilities and qualities, with the Mexican exporters. However, some will send representatives, known as coyotes, into Mexico to forward contract product. They may even provide financial and technical support during the planting season and assume responsibility for haulage to the border. Even the largest exporters have a 'broker' on the border. However, with many of these, the brokerage firm is owned by the exporter and often the firm is run by a member of the family. For an exporter whose English is not strong or who is unfamiliar with U.S. business practices and the characteristics of the U.S. market, these 'brokers' at the border serve an essential service. They allow access to the U.S. market to a firm that would otherwise not have it. Unfortunately the informational advantages which give 'brokers' their value in the market, also create the potential for abuses. For example, the Mexican exporter rarely, if ever, receives direct confirmation regarding the price actually paid by the final receiver for product consigned to a 'broker' and normally knows little or nothing about the receiver. As such, an unscrupulous 'broker' could: (a) claim consigned product was sold for a lower price than actually occurred;
