英文文献摘要：
Some studies have estimated a slowdown on agricultural productivity growth in the U.S and in some European countries. This article uses parametric and nonparametric methods to estimate (TFP) agricultural productivity growth in 10 South American countries in 1972-2006 with the objective of checking for a potential slowdown in these countries.
