The productivity gap between Mexico and the United States continues to widen. As mentioned above, in 1994, agricultural productivity in the United States was 10 times higher than Mexico; in 2010, the factor increased to 15.5. Competing with the United States is becoming harder as time passes and as the United States consolidates its lead as an agricultural exporter, increasing its own competitiveness with generous policy instruments, such as the Farm Bill, which affect international prices.
