Abstract

The structure of U.S. agricultural production changed dramatically during the 20th Century. Major technological innovations transformed the relationship between agricultural inputs and outputs, and contributed to rapid increases in agricultural productivity. However, evidence is mounting that suggests we have entered a new era, with substantially lower rates of productivity growth. In this article, we examine trends and spatial patterns in agricultural input use, production of outputs, and productivity. We focus on productivity growth over the period 1949–2002, and find a statistically significant slowdown in productivity growth after 1990.

The analysis presented here is based on the book by Alston, et al (2010), which provides complete details on the data, sources, and analysis. The InSTePP (International Science and Technology Practice and Policy Center, University of Minnesota) production accounts that underpin this analysis consist of state-specific measures of the prices and quantities of 74 outputs and 58 inputs for the 48 contiguous U.S. states. In developing the InSTePP data, special attention was given to accounting for variation in the composition of input and output aggregates, with particular reference to the quality of inputs and outputs and the spatial dimensions.
