ENDNOTES 1. Due to uncertainties in the data regarding total population the average per capital income cannot be estimated with more precision. 2. An important aspect of quality is sanitation. U.S. produce is widely regarded as being safe to eat in fresh form. 3. The recent unrest in the State of Chiapas, as well as recurrent problems throughout other regions of Mexico, are in large part reflections of these divisions. 4. Sigma Alimentos commands about a 32 percent share of Mexico's processed meat market. The five largest firms, Sigma Alimentos, Kir, Zwam, Parma, and Donfer account for over 90 percent of the market. The balance of the market is shared among approximately 5,000 small firms. 5. Some supermarkets combat this image by creating shop-like areas, such as fresh tortilla making areas and delis, within the store. 6. There is a partially complete grain elevator. However, construction has stopped and the facility is for sale. 7. These are located at: Hermosillo, Chihuahua, Topolobampo, San Luis Potosi, Torre6n, Monterrey, Saltillo, Altamira/Tampico, Guadalajara, Manzanillo, Lazaro CAardenas, Mexico City, Veracruz, Coatzalcoalcos, Salina Cruz, and Progreso. 8. U.S. railroads customarily allow FNM to hold their equipment for 10-to-15 days before charging per diem fees. 9. Opinions of those interviewed differed widely. Some expressed conviction that the facilities would be built and would greatly improve on and off loading of cargos. Others expressed concerns regarding the ability of Ferropuertos, S.A. de C.V. to raise sufficient capital and that the facilities, as currently designed, will create congestion. 10. Remarks in a speech to the North American Road Transport Conference, Monterrey, Nuevo Le6n, September 28, 1993. 11. The gross vehicle weights allowed in each country differs according to the configuration of the rig (i.e., number of axles and, in the U.S., distance between axles) and the type of roadway. 12. In large part, the cessation of enforcement was due to widespread use of bribery by carriers to circumvent the regulations and extortion by law officials.
