 In spite of being a staple in the Mexican diet, Mexico's comparative advantage in agriculture is not in corn, but in horticulture, tropical fruits, and vegetables.Negotiators of NAFTA expected that through liberalization and mechanization of agriculture two-thirds of Mexican corn producers would naturally shift from corn production to horticultural and other labor-intensive crops such as fruits, nuts, vegetables, coffee and sugar cane.While horticultural trade has drastically increased due to NAFTA, it has not absorbed displaced workers from corn production (estimated at around 600,000).
