Agricultural Productivity Revisited

Abstract This paper describes production accounts for agriculture. Output is defined as gross production leaving the farm as opposed to real value added. Inputs are not limited to capital and labor but include intermediate inputs as well. We derive index numbers of gross output, capital, labor, and intermediate inputs. These data are used to construct indexes of total factor productivity. We then compare the contributions of input growth and productivity growth to economic growth. The important role of productivity growth in agriculture becomes immediately apparent.
