Agricultural Productivity Growth in the United States: Measurement, Trends, and Drivers

This report details the major factors in the U.S.'s agricultural growth over the past several decades. Between 1948 and 2011 agricultural output more than doubled, which the report attributes to increases in total factor productivity (output per unit of aggregate input). The study finds no significant statistical evidence that long-term agricultural productivity is slowing, but that increases in research and development investments may slow total factor productivity growth over time. It suggests private-sector investment in productivity-related science to continue encouraging agricultural growth.
